https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245511 --- Comment #2 from commit-hook@freebsd.org --- A commit references this bug: Author: pkubaj Date: Sat Apr 25 12:26:35 UTC 2020 New revision: 532950 URL: https://svnweb.freebsd.org/changeset/ports/532950 Log: 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.
