--- Comment #4 from Andi Kleen <andi-gcc at firstfloor dot org> ---
It seems sparc doesn't support comparisons in vectorization?
/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/vect-switch-ifcvt-1.c:13:7:
missed: not vectorized: relevant stmt not supported: _13 = _1 == 124;
the target check for vect_int is already just hard coded targets, so I don't
hink we can do much better than a architecture skip. otherwise have to put
probes for everything into the target tests.
proc check_effective_target_vect_int { } {
return [check_cached_effective_target_indexed vect_int {
expr {
[istarget i?86-*-*] || [istarget x86_64-*-*]
|| [istarget powerpc*-*-*]
|| [istarget amdgcn-*-*]
|| [istarget sparc*-*-*]
|| [istarget alpha*-*-*]
|| [istarget ia64-*-*]
|| [istarget aarch64*-*-*]
|| [is-effective-target arm_neon]
|| ([istarget mips*-*-*]
&& ([et-is-effective-target mips_loongson_mmi]
|| [et-is-effective-target mips_msa]))

|| ([istarget riscv*-*-*]
&& [check_effective_target_riscv_v])

}}]
}
