You still need to use lang/gcc5 to build lang/gcc6 on Power if = you are using the default /usr/bin/cc -> GCC 4.2.1 as the system compiler becau= se you need >=3D 4.9 to build version 5. USE_GCC=3D5 is only unnecessary/harmful when you used an external compiler = to build world that is C++11 capable and therefore builds /usr/bin/cc -> LLVM/Clang as the system compiler which is not capable of building lang/gcc= 5 as this bug states (see /usr/src/share/mk/src.opts.mk:489-498). As for tree-vect-loop.c, Mark is the expert on that one: https://lists.freebsd.org/pipermail/freebsd-toolchain/2017-October/003328.h= tml My patch is just a work-around. --=20 You are receiving this mail because: You are on the CC list for the bug.=
