lang/gcc9: deprecate

gcc9 is now EOL'd and shouldn't be used anymore.
Since this is the last release that builds on powerpc64 elfv1 (with GCC 4.2),
set the expiration date to FreeBSD 12.x EOL date.

lang/gcc9: update to 9.5.0

lang/gcc9: Relinquish maintainership

After working on (and largely maintaining) our GCC ports for more than
19 years, time has come to hand over the baton.

Sadly despite multiple requests nobody stepped up (even having waited
another 3+ months after relinquishing maintainership of gcc9-devel),
so pass maintainership to toolchain@.

Fix CONFLICTS entries of multiple ports

There have been lots of missing CONFLICTS_INSTALL entries, either
because conflicting ports were added without updating existing ports,
due to name changes of generated packages, due to mis-understanding
the format and semantics of the conflicts entries, or just due to
typoes in package names.

This patch is the result of a comparison of all files contained in
the official packages with each other. This comparison was based on
packages built with default options and may therefore have missed
further conflicts with optionally installed files.

Where possible, version numbers in conflicts entries have been
generalized, some times taking advantage of the fact that a port

lang/gcc9: fix build on powerpc64le

Backport patch from gcc9-devel to fix build.

lang/gcc9: Update to the GCC 9.4 release

This fixes more than 190 bugs compared to GCC 9.3.

files/patch-gcc_dumpfile.c has made it upstream in the meantime, so
remove it on our end.

Remove # $FreeBSD$ from Makefiles.

Update to MPC version 1.2.0 with the following changes:
 - New functions:
   . mpc_sum
   . mpc_dot
 - Several functions are more robust with a reduced exponent range
   (for example corresponding to IEEE 754 binary formats).
 - New mpcheck tool for comparison with the native C library (which
   is not installed by default).

Bump all directly dependent ports. Do not bump those indirectly
dependent via the lang/gcc* family since their run-time dependencies
and code generated should not be affected.

Back port part of r566885 | gerald | 2021-03-01 from lang/gcc9-devel:

  Remove the GRAPHITE option. Graphite still is a largely experimental

Align some formatting with the gcc9-devel port, removing unnecessary

  Also remove SSP_UNSAFE which was added by r327697 in 2013 to the
  pre-pre-...-predecessor of this port and does not appear necessary
  any longer.

Back port part of r555542 | gerald | 2020-11-17 from lang/gcc9-devel:

  Fold the PLUGINS option, which has been on by default, into standard

  since we enabled it 11 months ago, nor measurable overhead.

Improve upon revision 532950 by passing GCC optimization options via

lower priority and required files/patch-Makefile.in which we can now

lang/gcc9: build with base GCC on powerpc64 elfv1

Instead of using lang/gcc8 for bootstrapping gcc9 on powerpc64 elfv1, use
directly base gcc.
Necessary changes:
- CFLAGS_FOR_TARGET="-O0" CXXFLAGS_FOR_TARGET="-O0" BOOT_CFLAGS="-O0" in
CONFIGURE_ENV and MAKE_ENV. Otherwise bootstrapped compiler fails later in the
build with segfault.
- CRTSTUFF_T_CFLAGS has changed optimizations to -O0, instead of -O2. -O2 worked
in gcc8, because there was no -fno-asynchronous-unwind-tables flag added to
CRTSTUFF_T_CFLAGS. Since this works when building with clang on powerpc64 elfv2,
this patch is added to EXTRA_PATCHES, only on powerpc64 elfv1,
- BOOT_CFLAGS has added ? before =. This is to allow overriding BOOT_CFLAGS in
CONFIGURE_ENV and MAKE_ENV.
- A patch by Gustavo Romero to gcc/dumpfile.c is necessary to allow compiling
with base GCC, otherwise base GCC hits ICE. Incidentally, this patch alone also
fixes build for powerpc (32 bits) with base GCC.

Bump PORTREVISION for dependency change.

Update to the GCC 9.3 release, which fixes some 157 further bugs.

This remains the default version of GCC in the Ports Collection, and
this update mostly addresses regressions.

files/patch-powerpc32 was a backport from this release branch to begin
with and has now become obsolete. [1]

Temporarily apply a patch from upstream that addresses a build failure
on powerpc ("error: integer constant is too large for 'long' type").

This is already part of lang/gcc9-devel after r518494 and the 20191123
snapshot of GCC 9.2.1; it will be part of the GCC 9.3 release at which
point we can remove this local patch again.

Properly push down lang/gcc9/patch-clang-vec_step into the files/
subdirectory.

clang on rs6000/powerpc* unfortunately poisons user namespace by default
(without any special options or include files being required).

Until that changes (or GCC changes) we need to avoid using vec_step as a
variable name.

Update to GCC 9.2 release, the second in the GCC 9 series, which fixes
some 68 bugs.

This is the default version of GCC in the Ports Collection, and it just
got a bit more polish and stability.

Both files/patch-amd64-gcc-multilib-support and
files/patch-powerpc64-no-_GNU_SOURCE [1] have been integrated upstream
(and also been part of lang/gcc9-devel already), so remove them here.

PR:		239648 [1]

Ensure _GNU_SOURCE is now longer defined on powerpc64 (which was a
regression from the GCC 8 series).

The technical background is that a consolidation in upstream GCC made
non-GNU platforms include gnu-user.h and then undefined some macros
in rs6000/freebsd.h, but missed doing the same in rs6000/freebsd64.h.

The has now been included upstream and the current snapshot that the
lang/gcc9-devel port tracks; carrying files/patch-powerpc64-no-_GNU_SOURCE
in this port should become obsolete with the GCC 9.2 release.

(As this should be a very short-lived measure, bump PORTREVISION only
for powerpc64 to avoid all other users having to rebuild, too.)

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

lang/gcc*: Hide pkg-message during upgrades

PR:		239419
Approved by:	gerald (maintainer)

Welcome GCC 9.1, the first release of the GCC 9 series!

https://gcc.gnu.org/gcc-9/changes.html has a comprehensive overview of
many improvements and changes and https://gcc.gnu.org/gcc-8/porting_to.html
addresses issues you may encounter porting to this new version, though
this release series should have fewer of those than previous ones.

To provide a brief overview of some of the more noticable changes:

GCC's diagnostics now print source code with a left margin showing line
numbers.  This is configurable via -fno-diagnostics-show-line-numbers.
Plus there have been lots of further improvements around diagnostic
messages in general as -fopt-info.

As usual a large number of improvements to code generation, including
