I tried to build devel/freebsd-gcc9@powerpc on a powerpc64 (in an
ELFv1 clang environment) and it reported (listing just one of the
examples that pointed to vec_step):
/wrkdirs/usr/ports/devel/freebsd-gcc9/work-powerpc/gcc-9.2.0/gcc/tree-vect-loop.c:4595:12:
error: expected unqualified-id
tree vec_step = build_vector_from_val (cr_index_vector_type, step);
^
(Unsure if white handling will still end up with ^
pointing to vec_step.)
clang reserves a name that the gcc source code uses:
vec_step . (I'll not get into the long, messy history
of this name and multiple standards built on top of
C/C++, not necessarily in a language appropriate
way.)
It turns out that:

I do not know if other differences in the patch
lists might be important to other aspects (in
either direction).
