libgcc is newer than the one about to be installed. If so, don't install
the libgcc.
Having an older libgcc appear in the lookup may result in binaries not
running, as they need symbols from the newer libgcc.
Such a case is PR pkg/54506.
Leaves SunOS unchanged, by request from jperkin.
this might be the cause of weird missing -lz on the latest SmartOS bulk
build, which appears to use this package (e.g. graphics/glitz).
Bump PKGREVISION.
for ansi.h on netbsd.
gcc{7,8}: document same patch that already existed was upstreamed.
This patch is necessary to build GCC on NetBSD >= 9.0, since changes
to ansi.h resulted in not using the same include guards.
Fixes PR toolchain/54362
works and cabs*() handling is correct.
also:
- extract using bsdtar. saves about 4 minutes during extract for me.
- remove duplicated part of gcc/config/netbsd.h -- it's already
upstream by this version.
sun was added as joyent is patching for the same.
this code is only reached if compiling for i386 (or some variation of ppc)
netbsd's stack_chk_fail_local won't work for this.

add netbsd/arm EABI target. recognise dwarf2 unwinding in the common arm code.
switch convoluted stddef.h logic from relying on include guards having certain
names to only applying for netbsd, which should be the sole remaining user.
(necessary for netbsd/arm, which uses different include guards for ansi.h)

Bump PKGREVISION. bump gcc7-libs PKGREVISION above this one.
SPARC
Support for the SPARC M8 processor has been added.
The switches -mfix-ut700 and -mfix-gr712rc have been added to work around an erratum in LEON3FT processors.
Use of the Floating-point Multiply Single to Double (FsMULd) instruction can now be controlled by the -mfsmuld and -fno-fsmuld options.
RTEMS
The Ada run-time support uses now thread-local storage (TLS).
Support for RISC-V has been added.
Support for 64-bit PowerPC using the ELFv2 ABI with 64-bit long double has been added.

(NetBSD/mips64 progress further with gsed)
Adding gsed as a tool creates circular dependencies if pkgsrc gcc is used
as the bootstrap compiler.
Pointed out by jperkin, sorry.
This is a somewhat blind commit. I've long had issues on various platforms
with libgcc getting misconfigured (on netbsd/mips,arm,powerpc), for example
build failures see:
http://mail-index.netbsd.org/port-mips/2017/06/21/msg000832.html
testing GCC 7.1 with netbsd/mips64el I got a lot further using it, but
still didn't complete the build. It took hours to reach this failure,
so I'd rather blindly commit the same change in the hopes it might help
other architectures.
GCC Java removed, package now uses ISL 0.16.1
Release notes:
We are proud to announce the next, major release of the
GNU Compiler Collection, 7.1. This year we celebrated the 30th
anniversary of the first GCC beta release and this month
we will celebrate 30 years since the GCC 1.0 release.
GCC 7.1 is a major release containing substantial new
functionality not available in GCC 6.x or previous GCC releases.
The C++ frontend now has experimental support for all of the current C++17
draft, with the -std=c++1z and -std=gnu++1z options, and the libstdc++
library has most of the C++17 draft library features implemented too.
This releases features various improvements in the emitted diagnostics,
including improved locations, location ranges, suggestions for misspelled
identifiers, option names, fix-it hints and various new warnings
have been added.
The optimizers have been improved, with improvements appearing in all of
intra- and inter-procedural optimizations, link time optimizations and
various target backends, including, but not limited to, additions of store
merging pass, code hoisting optimization, loop splitting, and
shrink wrapping improvements.
The Address Sanitizer can now report uses of variables after leaving their
scope. GCC now can be configured for OpenMP 4.5 offloading to NVidia PTX
GPGPUs.
Some code that compiled successfully with older GCC versions might require
some code adjustments, see http://gcc.gnu.org/gcc-7/porting_to.html for
details.
See
https://gcc.gnu.org/gcc-7/changes.html
for more information about changes in GCC 7.1.
