Author: Timo Teräs <timo.teras@iki.fi> Alpine musl package provides libssp_nonshared.a. We link to it unconditionally, as otherwise we get link failures if some objects are -fstack-protector built and final link happens with -fno-stack-protector. This seems to be the common case when bootstrapping gcc, the piepatches do not seem to fully fix the crosstoolchain and bootstrap sequence wrt. stack-protector flag usage. --- gcc-6.1.0/gcc/gcc.c.orig +++ gcc-6.1.0/gcc/gcc.c @@ -870,8 +870,7 @@ #ifndef LINK_SSP_SPEC #ifdef TARGET_LIBC_PROVIDES_SSP -#define LINK_SSP_SPEC "%{fstack-protector|fstack-protector-all" \ - "|fstack-protector-strong|fstack-protector-explicit:}" +#define LINK_SSP_SPEC "-lssp_nonshared" #else #define LINK_SSP_SPEC "%{fstack-protector|fstack-protector-all" \ "|fstack-protector-strong|fstack-protector-explicit" \
