Changes compared to GCC 7.x
001-revert_register_mode_search.patch dropped
The underlying issue is described at the end of
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58139
It is fixed by the upstream commit:
3fa2798aa8
020-PR-libstdc-81797-Add-.NOTPARALLEL-to-include-Makefil.patch dropped due to already upstream
100-PR-rtl-optimization-83496.patch dropped due to already upstream
910-mbsd_multi.patch
modified to fix ambiguous overloaded inform() call error
gcc/input.h
header: define UNKNOWN_LOCATION ((source_location) 0)
- inform (0, "someone does not honour COPTS correctly, passed %d times",
- honour_copts);
+ inform (UNKNOWN_LOCATION, "someone does not honour COPTS correctly, passed %d times",
+ honour_copts);
940-no-clobber-stamp-bits.patch dropped due to fixed upstream by another way
upstream commit: 87b2d547f8
950-cpp_file_path_translation.patch dropped, Both -fmacro-prefix-map and -ffile-prefix-map are added
to gcc 8.1.0, if I understand it correctly, we should use -fmacro-prefix-map
usage: -fmacro-prefix-map=@var{old}=@var{new}
upstream commit: 859b51f836
-iremap exists as a flag for a long time, for backward compatibility, I think we should keep the
variable name unchanged but change its value in rules.mk for gcc 8.x and higher.

The recent build failures on various platforms were apparently caused by
the fact that LTO build support in the configure script does not check
if it has a suitable version of gcc and simply assumes that gcc-ar is
available and can be used for intermediate files.
Since we really don't need to build nasm with LTO, simply disable it and
keep the whole build more portable

On Debian 9 nasm does not build when we force it to use ranlib, for
macOSX this is needed. Only force this on macOSX and not on any other
OS, this should fix the build of nasm on Linux systems. On my Debian
system the nasm configure script selects gcc-ranlib and gcc-ar instead.

Packages libx264 and ffmpeg are built with ASM options on x86 platforms.
The current libx264 version no longer builds with YASM and requires NASM.
ffmpeg 3.x can be built with either YASM or NASM however, furture 4.x versions
will require NASM.

uClibc-ng 1.0.28 does not provide PF_VSOCK/AF_VSOCK definitions,
which causes iproute2 v4.16.0 compile errors.
In commit 57f2f80383b5 ("bits/socket.h: add missing defines")
necessary defines were included and iproute2 builds fine.
This commit now is part of uClibc-ng 1.0.30.
Lets update uClibc-ng to latest 1.0.30 version.

Newer GCC versions are reported to improve code size on various ARM
devices, which is why newer u-boot versions require them now.
There have also been user reports of data corruption issues fixed on
MIPS by updating from GCC 5 to GCC 7.
This update was previously held up by these two MIPS compile issues,
which have since been fixed:

With forced PIE and SSP support I ran into this assertion failure.

Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh,
avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain
and depends it means 'build gcc with libssp'.
Musl no longer uses libssp (1877bc9d8f), it has internal support, so
SSP_SUPPORT was disabled leading some package to not use SSP.
No information why Glibc and uClibc use libssp, but they may also provide
their own SSP support. uClibc used it own with commit 933b588e25 but it was
reverted in f3cacb9e84 without details.
Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT
if either USE_MUSL or GCC_LIBSSP.
