toolchain: Add GCC 9.1.0 release
Most of the patches are copied over from GCC 8.3.
The following patches are backported from the GCC 9.X development branch:
toolchain/gcc/patches/9.1.0/970-recompute-dom-fast-queries-before-vn.patch
toolchain/gcc/patches/9.1.0/975-g++-ICE-with-generic-lambda.patch
The specs file changed with gcc 9, now it contains "%@{L*}" instead of
"%{L*}" in older GCC versions.

Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
|
||||||
|
|
||||||
|
SVN-Revision: 8256
|
||||||
|
|
||||||
|
This patch brings over a feature from MirBSD:
|
||||||
|
* -fhonour-copts
|
||||||
|
If this option is not given, it's warned (depending
|
||||||
|
on environment variables). This is to catch errors
|
||||||
|
of misbuilt packages which override CFLAGS themselves.
|
||||||
|
|
||||||
|
This patch was authored by Thorsten Glaser <tg at mirbsd.de>
|
||||||
|
with copyright assignment to the FSF in effect.

I talked to Andrew about what files he changed in GCC and created and
|
||||||
|
tested this new patch. Andrew also mentioned changing some assembly
|
||||||
|
files in glibc but I don't see any use of '.section .note.GNU-stack' in
|
||||||
|
any assembly files in glibc (for any platform) so I wasn't planning on
|
||||||
|
creating a glibc to add them to mips glibc assembly language files.
|
||||||
|
|
||||||
|
OK to check in this patch?

Subject: [PATCH] gotools: fix compilation when making cross compiler
|
||||||
|
|
||||||
|
libgo is "the runtime support library for the Go programming language.
|
||||||
|
This library is intended for use with the Go frontend."
|
||||||
|
|
||||||
|
gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
|
||||||
|
the linker will complain that it cannot find it. That's because shared libgcc
|
||||||
|
is not present in the install directory yet. libgo.so was made without problem
|
||||||
|
because gcc will emit -lgcc_s when compiled with -shared option. When gotools
|
||||||
|
were being made, it was supplied with -static-libgcc thus no link option was
|
||||||
|
provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
|
||||||
|
for linking with libgo.so
|
||||||
|
|
||||||
|
- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
|
||||||
|
- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
|
||||||
|
|
||||||
|
When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
|
||||||
|
available after gcc pass2 completed and will meet the gotools link requirement
|
||||||
|
at gcc pass3
