toolchain/gcc: switch to version 7 by default 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: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83496 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84790 Signed-off-by: Felix Fietkau <nbd@nbd.name>

toolchain/gcc: use version 7.x for x86 by default This is needed for retpoline support, which mitigates the spectre attacks. Signed-off-by: Felix Fietkau <nbd@nbd.name>

toolchain/gcc: switch to version 8 by default Main motivation for this commit is the introduction of `-ffile-prefix-map=` which alows reproducible build path. Compile tested on Linux and macOS without errors on the following targets: * ath79 * imx6 * brcm2708 * brcm63xx * ixp4xx * ramips * sunxi * x86 Thanks to Andre for the iremap fixup.

toolchain/gcc: add GCC 8.1.0 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: https://github.com/gcc-mirror/gcc/commit/3fa2798aa887d141d86985240f03e2f3809e7e62 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: https://github.com/gcc-mirror/gcc/commit/87b2d547f8ac9778d66909b8726fe967d1efbc74 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: https://github.com/gcc-mirror/gcc/commit/859b51f83662d01e4f158ea9327db9ca37fe70b3 -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.

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.
