From 139f99c05880508b19308eed366d8fbf5804fbf9 Mon Sep 17 00:00:00 2001 From: Syrone Wong Date: Thu, 21 Jun 2018 23:08:10 +0800 Subject: 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.
