I've pushed an updated patch to "wip-gcc7" based on the latest 'core-updates'. The cross-compiler toolchain is still broken: it fails to build the very last GCC. For armhf, the build system tries to include "gnu/stubs-soft.h" during "./configure" and fails, even though it gets "--with-float=hard" as a flag. When building the AArch64 cross-compiler, GCC segfaults later in the process: build/genmatch --gimple ../../gcc-7.4.0/gcc/match.pd > tmp-gimple-match.c /gnu/store/vfqvdfdnd8fi9gcx710mpfaf0x4dfd37-bash-minimal-5.0/bin/bash: line 1: 1789 Segmentation fault build/genmatch --gimple ../../gcc-7.4.0/gcc/match.pd > tmp-gimple-match.c make[2]: *** [Makefile:2460: s-match] Error 139
