Changes in 2.2.5 (since 2.2.4):
* Notable improvements
** Greatly improved performance of bidirectional pipes.
The performance of bidirectional pipes, as created using 'open-pipe' or
'open-pipe*' in OPEN_BOTH mode, has been greatly improved. When reading
large blocks of binary data from a bidirectional pipe, the maximum
bandwidth has been increased by a factor of ~10^3 in some cases.
** New 'get-bytevector-some!' I/O primitive.
This new I/O primitive is similar to 'get-bytevector-some' from the
R6RS, except that it writes its data to a user-specified range of
indices in an existing bytevector. As a corollary, it is also now
possible to specify a maximum number of bytes to read. Note that
'get-bytevector-some', and now 'get-bytevector-some!', are unique among
Guile's I/O primitives in their support of efficient binary reads of
potentially large blocks while also allowing for short reads, to avoid
undesired blocking. Now these operations can be performed while also
avoiding heap-allocation.
'get-bytevector-some!' is needed to efficiently implement the new
bidirectional pipes, which are built upon R6RS custom binary
input/output ports.
** get-bytevector-{n!,some,some!} now support suspendable I/O.
Scheme implementations of 'get-bytevector-n!', 'get-bytevector-some',
and 'get-bytevector-some!' have been added to (ice-9 suspendable-ports).
As a result, these I/O operations now support suspendable I/O.
* Compiler improvements
** guild compile: Add -Wshadowed-toplevel.
Top-level definitions that shadow previous top-level definitions from
the same compilation unit will now trigger a compile-time warning, if
-Wshadowed-toplevel is enabled. It is enabled by default.
** guild compile: Add '-x' flag.
Passing "-x EXT" to 'guild compile' will now cause EXT to be recognized
as a valid source file name extension. For example, to compile R6RS
code, you might want to pass "-x .sls" so that files ending in ".sls"
can be found.
* Miscellaneous improvements
** Bootstrap optimization
eval.go and psyntax-pp.go are now built before the rest of the .go files
so that they are processed by a fast macro expander. This saves time
when using parallel builds.
** put-u8 now always writes a single byte, regardless of the port encoding.
Previously, (put-u8 PORT OCTET) worked as expected only when writing to
binary ports, i.e. those with port encoding "ISO-8859-1" a.k.a. Latin-1.
Strictly speaking, this meets the requirements of the R6RS 'put-u8',
which need only support binary ports. However, Guile in fact allows
binary I/O to be performed on any port, and yet 'put-u8' behaved in a
surprising way with other port encodings: it would perform a _textual_
I/O operation, writing the character with Unicode scalar value OCTET.
Now, 'put-u8' always writes a single byte with value OCTET, regardless
of the port encoding.
** Optimize fixnum exact integer square roots.
'exact-integer-sqrt' now avoids heap allocation when applied to a
fixnum. 'sqrt' now avoids heap allocation when applied to a fixnum
that's a perfect square. Fewer heap allocations are now required when
applying 'sqrt' to a square of an exact rational whose numerator or
denominator are fixnums.
** scm_mkstrport: Optimize the POS -> BYTE_POS conversion.
scm_mkstrport now avoids an unnecessary heap allocation and conversion
to UTF-8, when STR is provided and POS is non-zero.
** SRFI-19: Support ~N in string->date.
Support for the ~N escape, which allows fractions of a second to be
parsed, is now supported in SRFI-19 'string->date'.
** SRFI-19: Update the leap second table.
The leap on 1 January 2017 was added to SRFI-19's leap second table.
** stexi->shtml: Add support for @i, @math, @tie and @dots.
stexi->shtml is now able to convert @i, @math, @tie and @dots to HTML.
** Define AT_SYMLINK_NOFOLLOW, AT_NO_AUTOMOUNT, and AT_EMPTY_PATH.
AT_SYMLINK_FOLLOW, AT_NO_AUTOMOUNT, and AT_EMPTY_PATH are now available
from Scheme, if supported on the platform.
** Improvements to the 'time' macro from (ice-9 time).
The 'time' macro now supports expressions that return multiple values.
It has also been rewritten as a hygienic 'syntax-rules' macro.
Previously, it was built using 'define-macro', and was therefore
unhygienic. This is not merely an internal implementation detail, but
is potentially relevant to any user of the 'time' macro, since it could
lead to unintended variable capture and other problems.
** Clarify the documentation for 'nil?'.
See commit b44f505f1571fc9c42e58982f161a9cfc81fb7f4.
** Clarify the manual's "Processes" section.
See commit 8cdd3a0773930ca872a13aada7a1344f03bb382b.
** Avoid 'with-latin1-locale' in binary I/O tests.
See commit 162a031e5f2c64cd23fcf069fb7b5071196f9527.
** Update user-visible copyright years.
* Bug fixes
** Avoid regexp ranges in HTTP inter-protocol exploitation check.
The regular expression used to check for HTTP inter-protocol
exploitation attacks previously used a character range '0-9', whose
meaning depends on the current locale. This has now been fixed.
** Fixes to the SRFI-19 time/date library.
*** TAI-to-UTC conversion leaps at the wrong time.
<https://bugs.gnu.org/21911>
*** time-utc->date shows bogus zone-dependent leap second.
<https://bugs.gnu.org/22034>
*** Manual incorrectly describes Julian Date.
<https://bugs.gnu.org/21902>
*** date->string duff ISO 8601 negative years.
<https://bugs.gnu.org/21903>
*** date->string duff ISO 8601 format for non-4-digit years.
<https://bugs.gnu.org/21904>
*** julian-day->date negative input breakage.
<https://bugs.gnu.org/21906>
*** time-duration screws up negative durations.
<https://bugs.gnu.org/26162>
*** time-difference doesn't detect error of differing time types.
<https://bugs.gnu.org/26163>
** Improve overflow checks in bytevector, string, and I/O operations.
Several numerical computations, performed using primitive C arithmetic
in Guile's core bytevector, string, and I/O operations, have been
rewritten to avoid overflows.
** Fix type inferencing for 'nil?' and 'null?' predicates.
Previously, the compiler would sometimes miscompile certain combinations
of 'nil?' and 'null?' predicates present within the same top-level form.
See <https://bugs.gnu.org/33036>.
** Fix 'atomic-box-compare-and-swap!'.
Previously, 'atomic-box-compare-and-swap!' would sometimes spuriously
fail on architectures based on Load-Linked/Store-Conditional (LL/SC)
synchronication primitives (e.g. ARM, PowerPC, and MIPS) in a way that
was undetectable by the caller. See <https://bugs.gnu.org/32786>.
** Make URI handling locale independent.
Previously, procedures in (web uri) would misbehave in some locales
including sv_SE. See <https://bugs.gnu.org/35785>.
** Strings, i18n: Limit the use of alloca to approximately 8 kilobytes.
Previously, 'string-locale-ci=?', 'string-locale-ci<?',
'string-locale<?', 'string-locale-{downcase,upcase,titlecase}' and
'string-normalize-{nfd,nfc,nfkd,nfkc}' would overflow the C stack when
applied to very large strings.
** Fix documentation of R6RS 'binary-port?' to reflect reality.
Previously, the documentation incorrectly stated that 'binary-port?'
always returns #t. In fact, it returns #t if and only if the port
encoding is "ISO-8859-1". The documentation for 'binary-port?' and
'textual-port?' has been rewritten to reflect the current reality, and
also to leave open the possibility of changing the behavior of these
predicates in a future version of Guile.
** Avoid passing NULL to 'memcpy' and 'memcmp'.
Previously, NULL was sometimes passed to 'memcpy' or 'memcmp' when the
size argument was 0.
** Save and restore errno in the signal handler.
Previously, Guile's synchronous C signal handler failed to save and
restore 'errno', although it might change its value. This could
potentially lead to spurious corruptions of 'errno' within threads
interrupted by signals.
** scm_to_stringn: Avoid passing NULL to c_strcasecmp.
<https://lists.gnu.org/archive/html/guile-user/2019-05/msg00070.html>
** r6rs-ports: Accept 'port-position' values greater than 2^32.
<https://bugs.gnu.org/32161>
** r6rs-ports: 'put-bytevector' accepts 64-bit integers.
Fixed in commit 741c45458da0831a12a4f8d729814bf9f2cb6571.

The OpenMP subproject of LLVM contains the components required to build an
executable OpenMP program that are outside the compiler itself.
Here you can find the code for the runtime library against which code compiled
by clang -fopenmp must be linked before it can run.
Changelog:
Changes affecting backwards compatibility
shr is now sign preserving. Use -d:nimOldShiftRight to enable the old behavior globally.
The isLower, isUpper family of procs in strutils/unicode operating on strings have been deprecated since it was unclear what these do. Note that the much more useful procs that operate on char or Rune are not affected.
strutils.editDistance has been deprecated, use editdistance.editDistance or editdistance.editDistanceAscii instead.
The OpenMP parallel iterator `||` now supports any #pragma omp directive and not just #pragma omp parallel for. See OpenMP documentation.
The default annotation is parallel for, if you used OpenMP without annotation the change is transparent, if you used annotations you will have to prefix your previous annotations with parallel for.
Furthermore, an overload with positive stepping is available.
The unchecked pragma was removed, instead use system.UncheckedArray.
The undocumented #? strongSpaces parsing mode has been removed.
The not operator is now always a unary operator, this means that code like assert not isFalse(3) compiles.
getImpl on a var or let symbol will now return the full IdentDefs tree from the symbol declaration instead of just the initializer portion.
Methods are now ordinary “single” methods, only the first parameter is used to select the variant at runtime. For backwards compatibility use the new --multimethods:on switch.
Generic methods are now deprecated; they never worked well.
Compile time checks for integer and float conversions are now stricter. For example, const x = uint32(-1) now gives a compile time error instead of being equivalent to const x = 0xFFFFFFFF'u32.
Using typed as the result type in templates/macros now means “expression with a type”. The old meaning of typed is preserved as void or no result type at all.
A bug allowed macro foo(): int = 123 to compile even though a macro has to return a NimNode. This has been fixed.
With the exception of uint and uint64, conversion to unsigned types are now range checked during runtime.
Macro arguments of type typedesc are now passed to the macro as NimNode like every other type except static. Use typed for a behavior that is identical in new and old Nim. See the RFC Pass typedesc as NimNode to macros for more details.
Breaking changes in the standard library
osproc.execProcess now also takes a workingDir parameter.
std/sha1.secureHash now accepts openArray[char], not string. (Former successful matches should keep working, though former failures will not.)
options.UnpackError is no longer a ref type and inherits from system.Defect instead of system.ValueError.
system.ValueError now inherits from system.CatchableError instead of system.Defect.
The procs parseutils.parseBiggestInt, parseutils.parseInt, parseutils.parseBiggestUInt and parseutils.parseUInt now raise a ValueError when the parsed integer is outside of the valid range. Previously they sometimes raised an OverflowError and sometimes they returned 0.
The procs parseutils.parseBin, parseutils.parseOct and parseutils.parseHex were not clearing their var parameter number and used to push its value to the left when storing the parsed string into it. Now they always set the value of the parameter to 0 before storing the result of the parsing, unless the string to parse is not valid (then the value of number is not changed).
streams.StreamObject now restricts its fields to only raise system.Defect, system.IOError and system.OSError. This change only affects custom stream implementations.
nre’s RegexMatch.{captureBounds,captures}[] no longer return Option or nil/"", respectively. Use the newly added n in p.captures method to check if a group is captured, otherwise you’ll receive an exception.
nre’s RegexMatch.{captureBounds,captures}.toTable no longer accept a default parameter. Instead uncaptured entries are left empty. Use Table.getOrDefault() if you need defaults.
nre’s RegexMatch.captures.{items,toSeq} now returns an Option[string] instead of a string. With the removal of nil strings, this is the only way to indicate a missing match. Inside your loops, instead of capture == "" or capture == nil, use capture.isSome to check if a capture is present, and capture.get to get its value.
nre’s replace() no longer throws ValueError when the replacement string has missing captures. It instead throws KeyError for named captures, and IndexError for unnamed captures. This is consistent with RegexMatch.{captureBounds,captures}[].
splitFile now correctly handles edge cases, see #10047.
isNil is no longer false for undefined in the JavaScript backend: now it’s true for both nil and undefined. Use isNull or isUndefined if you need exact equality: isNil is consistent with ===, isNull and isUndefined with ==.
several deprecated modules were removed: ssl, matchers, httpserver, unsigned, actors, parseurl
two poorly documented and not used modules (subexes, scgi) were moved to graveyard (they are available as Nimble packages)
procs string.add(int) and string.add(float) which implicitly convert ints and floats to string have been deprecated. Use string.addInt(int) and string.addFloat(float) instead.
case object branch transitions via system.reset are deprecated. Compile your code with -d:nimOldCaseObjects for a transition period.
base64 module: The default parameter newLine for the encode procs was changed from "\13\10" to the empty string "".
Breaking changes in the compiler
The compiler now implements the “generic symbol prepass” for when statements in generics, see bug #8603. This means that code like this does not compile anymore:
proc enumToString*(enums: openArray[enum]): string =
# typo: 'e' instead 'enums'
when e.low.ord >= 0 and e.high.ord < 256:
result = newString(enums.len)
else:
result = newString(enums.len * 2)
discard x is now illegal when x is a function symbol.
Implicit imports via --import: module in a config file are now restricted to the main package.
Library additions
There is a new stdlib module std/editdistance as a replacement for the deprecated strutils.editDistance.
There is a new stdlib module std/wordwrap as a replacement for the deprecated strutils.wordwrap.
Added split, splitWhitespace, size, alignLeft, align, strip, repeat procs and iterators to unicode.nim.
Added or for NimNode in macros.
Added system.typeof for more control over how type expressions can be deduced.
Added macros.isInstantiationOf for checking if the proc symbol is instantiation of generic proc symbol.
Added the parameter isSorted for the sequtils.deduplicate proc.
Added os.relativePath.
Added parseopt.remainingArgs.
Added os.getCurrentCompilerExe (implemented as getAppFilename at CT), can be used to retrieve the currently executing compiler.
Added xmltree.toXmlAttributes.
Added std/sums module for fast summation functions.
Added Rusage, getrusage, wait4 to the posix interface.
Added the posix_utils module.
Added system.default.
Added sequtils.items for closure iterators, allows closure iterators to be used by the mapIt, filterIt, allIt, anyIt, etc.
Library changes
The string output of macros.lispRepr proc has been tweaked slightly. The dumpLisp macro in this module now outputs an indented proper Lisp, devoid of commas.
Added macros.signatureHash that returns a stable identifier derived from the signature of a symbol.
In strutils empty strings now no longer match as substrings.
The Complex type is now a generic object and not a tuple anymore.
The ospaths module is now deprecated, use os instead. Note that os is available in a NimScript environment but unsupported operations produce a compile-time error.
The parseopt module now supports a new flag allowWhitespaceAfterColon (default value: true) that can be set to false for better Posix interoperability. (Bug #9619.)
os.joinPath and os.normalizePath handle edge cases like "a/b/../../.." differently.
securehash was moved to lib/deprecated.
The switch -d:useWinAnsi is not supported anymore.
In times module, procs format and parse accept a new optional DateTimeLocale argument for formatting/parsing dates in other languages.
Language additions
Vm support for float32<->int32 and float64<->int64 casts was added.
There is a new pragma block noSideEffect that works like the gcsafe pragma block.
added os.getCurrentProcessId.
User defined pragmas are now allowed in the pragma blocks.
Pragma blocks are no longer eliminated from the typed AST tree to preserve pragmas for further analysis by macros.
Custom pragmas are now supported for var and let symbols.
Tuple unpacking is now supported for constants and for loop variables.
Case object branches can be initialized with a runtime discriminator if possible discriminator values are constrained within a case statement.
Language changes
The standard extension for SCF (source code filters) files was changed from .tmpl to .nimf, it’s more recognizable and allows tools like Github to recognize it as Nim, see #9647. The previous extension will continue to work.
Pragma syntax is now consistent. Previous syntax where type pragmas did not follow the type name is now deprecated. Also pragma before generic parameter list is deprecated to be consistent with how pragmas are used with a proc. See #8514 and #1872 for further details.
Hash sets and tables are initialized by default. The explicit initHashSet, initTable, etc. are not needed anymore.
Tool changes
jsondoc now includes a moduleDescription field with the module description. jsondoc0 shows comments as its own objects as shown in the documentation.
nimpretty: –backup now defaults to off instead of on and the flag was undocumented; use git instead of relying on backup files.
koch now defaults to build the latest stable Nimble version unless you explicitly ask for the latest master version via --latest.
Compiler changes
The deprecated fmod proc is now unavailable on the VM.
A new --outdir option was added.
The compiled JavaScript file for the project produced by executing nim js will no longer be placed in the nimcache directory.
The --hotCodeReloading has been implemented for the native targets. The compiler also provides a new more flexible API for handling the hot code reloading events in the code.
The compiler now supports a --expandMacro:macroNameHere switch for easy introspection into what a macro expands into.
The -d:release switch now does not disable runtime checks anymore. For a release build that also disables runtime checks use -d:release -d:danger or simply -d:danger.

Major work was done by x0ret to correct function signatures and include annotation types
Handle Python 3.6 STORE_ANNOTATION
Friendlier assembly output
LOAD_CONST replaced by LOAD_STR where appropriate to simplify parsing and improve clarity
remove unneeded parenthesis in a generator expression when it is the single argument to the function
Bug in noting an async function
Handle unicode docstrings and fix docstring bugs
Add uncompyle6 command-line short option -T as an alternate for --tree+
Some grammar cleanup
Built-in Python modules are built from extracted Python sources and
therefere bound to that specific Python version. For example, trying to
build a module from Python 2.7.16 against an installed Python 2.7.13 is
likely to cause errors.
This commit makes built-in Python modules depend on the full current
Python version.
What’s New in Libc++ 8.0.0?
API Changes
Building libc++ for Mac OSX 10.6 is not supported anymore.
Starting with LLVM 8.0.0, users that wish to link together translation units built with different versions of libc++’s headers into the same final linked image MUST define the _LIBCPP_HIDE_FROM_ABI_PER_TU macro to 1 when building those translation units. Not defining _LIBCPP_HIDE_FROM_ABI_PER_TU to 1 and linking translation units built with different versions of libc++’s headers together may lead to ODR violations and ABI issues. On the flipside, code size improvements should be expected for everyone not defining the macro.
Starting with LLVM 8.0.0, std::dynarray has been removed from the library. std::dynarray was a feature proposed for C++14 that was pulled from the Standard at the last minute and was never standardized. Since there are no plans to standardize this facility it is being removed.
Starting with LLVM 8.0.0, std::bad_array_length has been removed from the library. std::bad_array_length was a feature proposed for C++14 alongside std::dynarray, but it never actually made it into the C++ Standard. There are no plans to standardize this feature at this time. Formally speaking, this removal constitutes an ABI break because the symbols were shipped in the shared library. However, on macOS systems, the feature was not usable because it was hidden behind availability annotations. We do not expect any actual breakage to happen from this change.
Clang Tools 8.0.0:
Improvements to clangd
clangd now adds namespace qualifiers in code completion, for example, if you type “vec”, the list of completions will include “std::vector”.
When a global index is available, clangd will use it to augment the results of “go to definition” and “find references” queries. Global index also enables global code completion, which suggests symbols that are not imported in the current file and automatically inserts the missing #include directives.
clangd stores the symbol index on disk in a new compact binary serialization format. It is 10x more compact than YAML and 40% more compact than gzipped YAML.
clangd has a new efficient symbol index suitable for complex and fuzzy queries and large code bases (e.g., LLVM, Chromium). This index is used for code completion, go to definition, and cross-references. The architecture of the index allows for complex and fuzzy retrieval criteria and sophisticated scoring.
clangd has a new LSP extension that communicates information about activity on clangd’s per-file worker thread. This information can be displayed to users to let them know that the language server is busy with something. For example, in clangd, building the AST blocks many other operations.
clangd has a new LSP extension that allows the client to supply the compilation commands over LSP, instead of finding compile_commands.json on disk.
clangd has a new LSP extension that allows the client to request fixes to be sent together with diagnostics, instead of asynchronously.
clangd has a new LSP extension that allows the client to resolve a symbol in a light-weight manner, without retrieving further information (like definition location, which may require consulting an index).
Improvements to clang-query
A new command line parameter --preload was added to run commands from a file and then start the interactive interpreter.
The command q can was added as an alias for quit to exit the clang-query interpreter.
It is now possible to bind to named values (the result of let expressions).
It is now possible to write comments in clang-query code. This is primarily useful when using script-mode. Comments are all content following the # character on a line.
The new set print-matcher true command now causes clang-query to print the evaluated matcher together with the resulting bindings.
A new output mode detailed-ast was added to clang-query. The existing dump output mode is now a deprecated alias for detailed-ast
Output modes can now be enabled or disabled non-exclusively.
Improvements to clang-tidy
New abseil-duration-comparison check.
Checks for comparisons which should be done in the absl::Duration domain instead of the float of integer domains.
New abseil-duration-division check.
Checks for uses of absl::Duration division that is done in a floating-point context, and recommends the use of a function that returns a floating-point value.
New abseil-duration-factory-float check.
Checks for cases where the floating-point overloads of various absl::Duration factory functions are called when the more-efficient integer versions could be used instead.
New abseil-duration-factory-scale check.
Checks for cases where arguments to absl::Duration factory functions are scaled internally and could be changed to a different factory function.
New abseil-duration-subtraction check.
Checks for cases where subtraction should be performed in the absl::Duration domain.
New abseil-faster-strsplit-delimiter check.
Finds instances of absl::StrSplit() or absl::MaxSplits() where the delimiter is a single character string literal and replaces with a character.
New abseil-no-internal-dependencies check.
Gives a warning if code using Abseil depends on internal details.
New abseil-no-namespace check.
Ensures code does not open namespace absl as that violates Abseil’s compatibility guidelines.
New abseil-redundant-strcat-calls check.
Suggests removal of unnecessary calls to absl::StrCat when the result is being passed to another absl::StrCat or absl::StrAppend.
New abseil-str-cat-append check.
Flags uses of absl::StrCat() to append to a std::string. Suggests absl::StrAppend() should be used instead.
New abseil-upgrade-duration-conversions check.
Finds calls to absl::Duration arithmetic operators and factories whose argument needs an explicit cast to continue compiling after upcoming API changes.
New bugprone-too-small-loop-variable check.
Detects those for loops that have a loop variable with a “too small” type which means this type can’t represent all values which are part of the iteration range.
New cppcoreguidelines-macro-usage check.
Finds macro usage that is considered problematic because better language constructs exist for the task.
New google-objc-function-naming check.
Checks that function names in function declarations comply with the naming conventions described in the Google Objective-C Style Guide.
New misc-non-private-member-variables-in-classes check.
Finds classes that not only contain the data (non-static member variables), but also have logic (non-static member functions), and diagnoses all member variables that have any other scope other than private.
New modernize-avoid-c-arrays check.
Finds C-style array types and recommend to use std::array<> / std::vector<>.
New modernize-concat-nested-namespaces check.
Checks for uses of nested namespaces in the form of namespace a { namespace b { ... }} and offers change to syntax introduced in C++17 standard: namespace a::b { ... }.
New modernize-deprecated-ios-base-aliases check.
Detects usage of the deprecated member types of std::ios_base and replaces those that have a non-deprecated equivalent.
New modernize-use-nodiscard check.
Adds [[nodiscard]] attributes (introduced in C++17) to member functions to highlight at compile time which return values should not be ignored.
New readability-const-return-type check.
Checks for functions with a const-qualified return type and recommends removal of the const keyword.
New readability-isolate-decl check.
Detects local variable declarations declaring more than one variable and tries to refactor the code to one statement per declaration.
New readability-magic-numbers check.
Detects usage of magic numbers, numbers that are used as literals instead of introduced via constants or symbols.
New readability-redundant-preprocessor check.
Finds potentially redundant preprocessor directives.
New readability-uppercase-literal-suffix check.
Detects when the integral literal or floating point literal has non-uppercase suffix, and suggests to make the suffix uppercase. The list of destination suffixes can be optionally provided.
New alias cert-dcl16-c to readability-uppercase-literal-suffix added.
New alias cppcoreguidelines-avoid-c-arrays to modernize-avoid-c-arrays added.
New alias cppcoreguidelines-non-private-member-variables-in-classes to misc-non-private-member-variables-in-classes added.
New alias hicpp-avoid-c-arrays to modernize-avoid-c-arrays added.
New alias hicpp-uppercase-literal-suffix to readability-uppercase-literal-suffix added.
The cppcoreguidelines-narrowing-conversions check now detects more narrowing conversions: - integer to narrower signed integer (this is compiler implementation defined), - integer - floating point narrowing conversions, - floating point - integer narrowing conversions, - constants with narrowing conversions (even in ternary operator).
The objc-property-declaration check now ignores the Acronyms and IncludeDefaultAcronyms options.
The readability-redundant-smartptr-get check does not warn about calls inside macros anymore by default.
The readability-uppercase-literal-suffix check does not warn about literal suffixes inside macros anymore by default.
Clang 8.0.0:
Major New Features
* Clang supports use of a profile remapping file, which permits profile data captured for one version of a program to be applied when building another version where symbols have changed (for example, due to renaming a class or namespace). See the UsersManual for details.
* Clang has new options to initialize automatic variables with a pattern. The default is still that automatic variables are uninitialized. This isn’t meant to change the semantics of C and C++. Rather, it’s meant to be a last resort when programmers inadvertently have some undefined behavior in their code. These options aim to make undefined behavior hurt less, which security-minded people will be very happy about.
* Improvements to Clang’s diagnostics
Non-comprehensive list of changes in this release
* The experimental feature Pretokenized Headers (PTH) was removed in its entirely from Clang. The feature did not properly work with about 1/3 of the possible tokens available and was unmaintained.
* The internals of libc++ include directory detection on MacOS have changed. Instead of running a search based on the -resource-dir flag, the search is now based on the path of the compiler in the filesystem. The default behaviour should not change. However, if you override -resource-dir manually and rely on the old behaviour you will need to add appropriate compiler flags for finding the corresponding libc++ include directory.
* The integrated assembler is used now by default for all MIPS targets.
* Improved support for MIPS N32 ABI and MIPS R6 target triples.
* Clang now includes builtin functions for bitwise rotation of common value sizes, such as: __builtin_rotateleft32
* Improved optimization for the corresponding MSVC compatibility builtins such as _rotl().
8.0.0:
Non-comprehensive list of changes in this release
* The llvm-cov tool can now export lcov trace files using the -format=lcov option of the export command.
* The add_llvm_loadable_module CMake macro has been removed. The add_llvm_library macro with the MODULE argument now provides the same functionality. See Writing an LLVM Pass.
* For MinGW, references to data variables that might need to be imported from a dll are accessed via a stub, to allow the linker to convert it to a dllimport if needed.
* Added support for labels as offsets in .reloc directive.
* Support for precise identification of X86 instructions with memory operands, by using debug information. This supports profile-driven cache prefetching. It is enabled with the -x86-discriminate-memops LLVM Flag.
* Support for profile-driven software cache prefetching on X86. This is part of a larger system, consisting of: an offline cache prefetches recommender, AutoFDO tooling, and LLVM. In this system, a binary compiled with -x86-discriminate-memops is run under the observation of the recommender. The recommender identifies certain memory access instructions by their binary file address, and recommends a prefetch of a specific type (NTA, T0, etc) be performed at a specified fixed offset from such an instruction’s memory operand. Next, this information needs to be converted to the AutoFDO syntax and the resulting profile may be passed back to the compiler with the LLVM flag -prefetch-hints-file, together with the exact same set of compilation parameters used for the original binary. More information is available in the RFC.
* Windows support for libFuzzer (x86_64).

Windows
https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=8.3
A C++ Microsoft ABI bitfield layout bug, PR87137 has been fixed. A non-field declaration could cause the current bitfield allocation unit to be completed, incorrectly placing a following bitfield into a new allocation unit. The Microsoft ABI is selected for:
Mingw targets
PowerPC, IA-32 or x86-64 targets when the -mms-bitfields option is specified, or __attribute__((ms_struct)) is used
SuperH targets when the -mhitachi option is specified, or __attribute__((renesas)) is used
GCC 8 introduced additional cases of this defect, but rather than resolve only those regressions, we decided to resolve all the cases of this defect in single change.
This release includes fixes to the compiler, the linker, the go command,
the runtime, and the os package.
Same as for go111, remove the pkg/bootstrap tree from the package.
This release includes fixes to the compiler, the linker, the go command, the
runtime, and the os package.
While here, remove pkg/bootstrap from the package, as it is only used
for bootstrapping.
configure forced to pass `-g' to CFLAGS and did not strip resulting binaries and
libraries. Pass `--disable-debug-symbols' and `--enable-strip' to respectively
address that.
Fix PR pkg/54228 reported by matt farnsworth.
While here, avoid to pass `-Wl,-z,wxneeded' to LDFLAGS on NetBSD.
Main changes:
* some quality-of-life bug fixes,
* many improvements to the documentation,
* a critical bug fix related to primitive projections and native_compute,
* several additional Coq libraries shipped with the Windows installer.
