* The default mode for C++ is now -std=gnu++14 instead of -std=gnu++98.
# ARM
Support for revisions of the ARM architecture prior to ARMv4t has been
deprecated and will be removed in a future GCC release. The -mcpu and
-mtune values that are deprecated are: arm2, arm250, arm3, arm6,
arm60, arm600, arm610, arm620, arm7, arm7d, arm7di, arm70, arm700,
arm700i, arm710, arm720, arm710c, arm7100, arm7500, arm7500fe, arm7m,
arm7dm, arm7dmi, arm8, arm810, strongarm, strongarm110, strongarm1100,
strongarm1110, fa526, fa626. The value arm7tdmi is still
supported. The values of -march that are deprecated are:
armv2,armv2a,armv3,armv3m,armv4.
The ARM port now supports target attributes and pragmas. Please refer
to the documentation for details of available attributes and pragmas
as well as usage instructions.
Support has been added for the following processors (GCC identifiers
in parentheses): ARM Cortex-A32 (cortex-a32), ARM Cortex-A35
(cortex-a35) and ARM Cortex-R8 (cortex-r8). The GCC identifiers can be
used as arguments to the -mcpu or -mtune options, for example:
-mcpu=cortex-a32 or -mtune=cortex-a35.
Significantly reduces build time and dependencies. doc option is
enabled by default so there's no change without explicit
configuration.
From i3enedek on Freenode.
Splitting this into a separate doc package is left as an exercise for
the reader.

Target Specific Changes
IA-32/x86-64
GCC now supports the Intel CPU named Skylake with AVX-512 extensions
through -march=skylake-avx512. The switch enables the following ISA
extensions: AVX-512F, AVX512VL, AVX-512CD, AVX-512BW, AVX-512DQ.
The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.
Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden). Existing SHA1
digests retained for now as an audit trail.
Object file converter
This utility can be used for converting object files between COFF/PE,
OMF, ELF and Mach-O formats for all 32-bit and 64-bit x86 platforms.
Can modify symbol names in object files. Can build, modify and
convert function libraries across platforms. Can dump object files
and executable files. Also includes a very good disassembler
supporting the SSE4, AVX, AVX2, AVX512, FMA3, FMA4, XOP and Knights
Corner instruction sets. Source code included (GPL).
This release is a bug-fix release, containing fixes for regressions in
GCC 4.9.1 and 4.9.0 relative to previous releases of GCC.
6 changes and 8 documentation fixes.
- to make pkglint clean, change directory organization, using BUILD_DIR= src etc.
- Add LICENSE= gnu-gpl-v2
- Use SUBST instead of ${SED} at do-install: target
- Newly installs example files
- (invocation without argument gives error as
Pass 1: Error: Cannot open file: 'test.m65'
but it is the same as prev. version and user should give input)
(upstream) Update 1.04 to 1.06
------------------------------
October 10, 2003
version 1.05 - added new directives .BANK, .SET 6, and .OPT LIST/NO LIST;
Preliminary support for .ATR disk images and the Atari++
emulator memory snapshots;
March 17, 2009
version 1.06 - allow negative offsets with .SET 6 directives; allow arithmentic
expressions in REPEAT blocks; Better detection of resized labels;
Fixed a buffer overflow problem; Added -l option to allow label output;
Compiling Windows executable with mingw
(pkgsrc)
- Instead of
"very evil hack to override CC, doing it via CONFIGURE_ENV doesn't work",
use CONFIGURE_ARGS

Bump version 7.6 to 7.6.1
-------
GDB 7.6.1 provides the following fixes and improvements to GDB 7.6:
* PR tdep/15420 (Cannot debug threaded programs on newer versions
of x86-solaris - Solaris 10, Update 10 or later)
* PR remote/15455 (QTro remote packet broken)
* PR build/15476 (Build failure due to incomplete enum type in utils.h)
* PR server/15594 (tls support in 64x32 x86 gdbserver doesn't extend
address to 64 bit)
* PR server/15075 (dprintf inteferes with "next")
* PR server/15434 (dprintf uses a synchronous 'continue' even in
non-stop mode)
* PR tui/14880 (in split register layouts, up results in assertion
failure in value.c)
* PR c++/15519 (GDB 7.6 is 94x slower than GDB 7.5.1 using a certain
core file)
* PR gdb/15837 (GDB prints entry values for local variables)
* PR gdb/15415 (gdb resolves symbolic links when passing argv[0])
* PR cli/15603 (CTRL-C can no longer interrupt inferior)
* PR gdb/15604 (gdbserver socket leak 7.5 regression)
different from the PR (When submitting patch to pkgsrc with
adding more patches, submitter should do cvs add
patches/patch-hoge, before creating the pkgsrc patch, thanks).
I belive both simulavr and avr-libc will be packaged fine with this.

4.7.3 to 4.8.3 -- From grepping 'avr' from NEWS file:
--------------
On AVR, the configure option --with-avrlibc supported since GCC 4.7.2
is turned on per default for all non-RTEMS configurations. This option
arranges for a better integration of [3]AVR Libc with avr-gcc. For
technical details, see [4]PR54461. To turn off the option in non-RTEMS
configurations, use --with-avrlibc=no. If the compiler is configured
for RTEMS, the option is always turned off.
* Support has been added for the AVR-specific configure option
--with-avrlibc=yes in order to arrange for better integration of
[3]AVR-Libc. This configure option is supported in avr-gcc 4.7.2
and newer and will only take effect in non-RTEMS configurations. If
avr-gcc is configured for RTEMS, the option will be ignored which
is the same as specifying --with-avrlibc=no. See [4]PR54461 for
more technical details.

--------------
For the changes for 4.7, see following page.
http://gcc.gnu.org/gcc-4.7/changes.html
(Picking up AVR related topic from above info):
The AVR port's libgcc has been improved and its multilib
structure has been enhanced. As a result, all objects
contributing to an application must either be compiled with
GCC versions up to 4.6.x or with GCC versions 4.7.1 or
later. If the compiler is used with AVR Libc, you need a
version that supports the new layout, i.e. implements #35407.
The AVR port's -mshort-calls command-line option has been
deprecated. It will be removed in the GCC 4.8 release. See
-mrelax for a replacement.
The AVR port only references startup code that clears .bss and
the common section resp. initializes the .data and .rodata
section provided respective sections (or subsections thereof)
are not empty, see PR18145.
Applications that put all static storage objects into
non-standard sections and / or define all static storage
objects in assembler modules, must reference __do_clear_bss
resp. __do_copy_data by hand or undefine the symbol(s) by
means of -Wl,-u,__do_clear_bss resp. -Wl,-u,__do_copy_data.
