Lua Lanes is a Lua extension library providing the possibility to run multiple
Lua states in parallel. It is intended to be used for optimizing performance
on multicore CPUs and to study ways to make Lua programs naturally parallel
to begin with.
Remove local function pr_open and use it from libmaa library.
So, now paexec requires libmaa.
"mkcmake help" shows configuring variables and descriptions for
targets.
Use mkc's feature "getdelim" instead of local implementation.
So, we need at least mk-configure 0.33.0
Optimization flags defaults to "-O2 -g"
3.6.1:
- Logging max memory reached at INFO rather than WARNING
- Pass arguments when wrapping sys.exit
- Remove win32/py2k special
- Ensure READY messages sent out by exiting worker are consumed prior to it actually existing.
- Pass max_memory_per_child to child worker process
- Fix compatibility with Python 2.7 on Windows
Fix use of uninitialized array.
As a rsult paexec generates incorrect shell command to run
on nodes. Seen with "clang-7.0.1" with -O2 and -D_FORTIFY_SOURCE=2
Add one line description to projects.
So, one can run "mkcmake help"
paexec -x:
* fix handling tasks with leading spaces
* fix handling tasks with backslashes
paargs:
* on SunOS-5.10 use /usr/xpg4/bin/sh
instead of horribly broken /bin/sh
Fix build failure on SunOS-5.10 (getdelim(3) is absent)
Introduce PAEXEC_SH environment variable
for fixing /bin/sh on SunOS-5.10
Introduce PAEXEC_FIND variable for regression tests (required on
SunOS-5.10)
Both files don't exist. If corrected, the first file would end up in
share/examples, and mk/check/check-interpreter.mk allows /usr/bin/env is
those files.
pkglint -r --network --only "migrate"
As a side-effect of migrating the homepages, pkglint also fixed a few
indentations in unrelated lines. These and the new homepages have been
checked manually.
pkglint --only "https instead of http" -r -F
With manual adjustments afterwards since pkglint 19.4.4 fixed a few
indentations in unrelated lines.
This mainly affects projects hosted at SourceForce, as well as
freedesktop.org, CTAN and GNU.
9.0.0:
Non-comprehensive list of changes in this release
ELF Improvements
ld.lld now has typo suggestions for flags: $ ld.lld --call-shared now prints unknown argument '--call-shared', did you mean '--call_shared'.
--allow-shlib-undefined and --no-allow-shlib-undefined options are added. --no-allow-shlib-undefined is the default for executables.
-nmagic and -omagic options are fully supported.
Segment layout has changed. PT_GNU_RELRO, which was previously placed in the middle of readable/writable PT_LOAD segments, is now placed at the beginning of them. This change permits lld-produced ELF files to be read correctly by GNU strip older than 2.31, which has a bug to discard a PT_GNU_RELRO in the former layout.
-z common-page-size is supported.
Diagnostics messages have improved. A new flag --vs-diagnostics alters the format of diagnostic output to enable source hyperlinks in Microsoft Visual Studio IDE.
Linker script compatibility with GNU BFD linker has generally improved.
The clang --dependent-library form of autolinking is supported.
This feature is added to implement the Windows-style autolinking for Unix. On Unix, in order to use a library, you usually have to include a header file provided by the library and then explicitly link the library with the linker -l option. On Windows, header files usually contain pragmas that list needed libraries. Compilers copy that information to object files, so that linkers can automatically link needed libraries. --dependent-library is added for implementing that Windows semantics on Unix.
AArch64 BTI and PAC are supported.
lld now supports replacing JAL with JALX instructions in case of MIPS-microMIPS cross-mode jumps.
lld now creates LA25 thunks for MIPS R6 code.
Put MIPS-specific .reginfo, .MIPS.options, and .MIPS.abiflags sections into corresponding PT_MIPS_REGINFO, PT_MIPS_OPTIONS, and PT_MIPS_ABIFLAGS segments.
The quality of RISC-V and PowerPC ports have greatly improved. Many applications can now be linked by lld. PowerPC64 is now almost production ready.
The Linux kernel for arm32_7, arm64, ppc64le and x86_64 can now be linked by lld.
x86-64 TLSDESC is supported.
DF_STATIC_TLS flag is set for i386 and x86-64 when needed.
The experimental partitioning feature is added to allow a program to be split into multiple pieces.
The feature allows you to semi-automatically split a single program into multiple ELF files called “partitions”. Since all partitions share the same memory address space and don’t use PLT/GOT, split programs run as fast as regular programs.
With the mechanism, you can start a program only with a “main” partition and load remaining partitions on-demand. For example, you can split a web browser into a main partition and a PDF reader sub-partition and load the PDF reader partition only when a user tries to open a PDF file.
See the documentation for more information.
If “-” is given as an output filename, lld writes the final result to the standard output. Previously, it created a file “-” in the current directory.
-z ifunc-noplt option is added to reduce IFunc function call overhead in a freestanding environment such as the OS kernel.
Functions resolved by the IFunc mechanism are usually dispatched via PLT and thus slower than regular functions because of the cost of indirection. With -z ifunc-noplt, you can eliminate it by doing text relocations at load-time. You need a special loader to utilize this feature. This feature is added for the FreeBSD kernel but can be used by any operating systems.
--undefined-glob option is added. The new option is an extension to --undefined to take a glob pattern instead of a single symbol name.
COFF Improvements
Like the ELF driver, lld-link now has typo suggestions for flags.
lld-link now correctly reports duplicate symbol errors for object files that were compiled with /Gy.
lld-link now correctly reports duplicate symbol errors when several resource (.res) input files define resources with the same type, name and language. This can be demoted to a warning using /force:multipleres.
lld-link now rejects more than one resource object input files, matching link.exe. Previously, lld-link would silently ignore all but one. If you hit this: Don’t pass resource object files to the linker, instead pass res files to the linker directly. Don’t put resource files in static libraries, pass them on the command line.
Having more than two /natvis: now works correctly; it used to not work for larger binaries before.
Undefined symbols are now printed only in demangled form. Pass /demangle:no to see raw symbol names instead.
Several speed and memory usage improvements.
lld-link now supports resource object files created by GNU windres and MS cvtres, not only llvm-cvtres.
The generated thunks for delayimports now share the majority of code among thunks, significantly reducing the overhead of using delayimport.
IMAGE_REL_ARM{,64}_REL32 relocations are supported.
Range extension thunks for AArch64 are now supported, so lld can create large executables for Windows/ARM64.
The following flags have been added: /functionpadmin
WebAssembly Improvements
Imports from custom module names are supported.
Symbols that are in llvm.used are now exported by default.
Initial support for PIC and dynamic linking has landed.
wasm-ld now add __start_/__stop_ symbols for data sections.
wasm-ld now doesn’t report an error on archives without a symbol index.
The following flags have been added: --emit-relocs
MinGW Improvements
lld now correctly links crtend.o as the last object file, handling terminators for the sections such as .eh_frame properly, fixing DWARF exception handling with libgcc and gcc’s crtend.o.
lld now also handles DWARF unwind info generated by GCC, when linking with libgcc.
PDB output can be requested without manually specifying the PDB file name, with the new option -pdb= with an empty value to the option. (The old existing syntax -pdb <filename> was more cumbersome to use with an empty parameter value.)
--no-insert-timestamp option is added as an alias to /timestamp:0.
Many more GNU ld options are now supported, which e.g. allows the lld MinGW frontend to be called by GCC.
The following options are added: --exclude-all-symbols, --appcontainer, --undefined
hwloc (Hardware Locality) 1.11.13
The most important change is support for upcoming Intel processors with
multiple Dies per CPU. hwloc release 2.1 will add a new "Die" object.
In the meantime 1.11.13 and 2.0.4 represent those Dies as "Die" groups.
Summary of the changes since 1.11.12:
* Add support for Linux 5.3 new sysfs cpu topology files with Die information.
* Add support for Intel v2 Extended Topology Enumeration in the x86 backend.
* Tiles, Modules and Dies are exposed as Groups for now.
+ HWLOC_DONT_MERGE_DIE_GROUPS=1 may be set in the environment to prevent
Die groups from being automatically merged with identical parent or
children.
* Ignore NUMA node information from AMD topoext in the x86 backend,
unless HWLOC_X86_TOPOEXT_NUMANODES=1 is set in the environment.
* Group objects have a new "dont_merge" attribute to prevent them from
being automatically merged with identical parent or children.
Provides fundamental abstractions for doing asynchronous programming
in R using promises. Asynchronous programming is useful for allowing a
single R process to orchestrate multiple tasks in the background while
also attending to something else. Semantics are similar to
'JavaScript' promises, but with a syntax that is idiomatic R.
LLVM 8.0.1 is now available! Download it now, or read the release notes.
This release contains bug-fixes for the LLVM 8.0.0 release. This
release is API and ABI compatible with 8.0.0.
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.
3.6.0.0:
- Add support of sending parent process death signal.
- Previous fix for handling timeouts caused a problem in warm shutdowns due
to use of deepcopy.
We now use a shallow copy of the cache and do so only when it is needed.
- Cleanup old checks and workarounds for Python versions we no longer support.
Version 1.11.12
* Fix a corner case of hwloc_topology_restrict() where children would
become out-of-order.
* Fix the return length of export_xmlbuffer() functions to always
include the ending \0.
Version 1.11.11
* Add support for Hygon Dhyana processors in the x86 backend,
thanks to Pu Wen for the patch.
* Fix symbol renaming to also rename internal components,
thanks to Evan Ramos for the patch.
* Fix build on HP-UX, thanks to Richard Lloyd for reporting the issues.
* Detect PCI link speed without being root on Linux >= 4.13.
