For some target like target=amdgcn-amdhsa, we need to take care of
vector bool types prior to general vector mode types. Or we may have
the asm check failure as below.
gcc.target/gcn/cond_smax_1.c scan-assembler-times \\tv_cmp_gt_i32\\tvcc,
s[0-9]+, v[0-9]+ 80
gcc.target/gcn/cond_smin_1.c scan-assembler-times \\tv_cmp_gt_i32\\tvcc,
s[0-9]+, v[0-9]+ 80
gcc.target/gcn/cond_umax_1.c scan-assembler-times \\tv_cmp_gt_i32\\tvcc,
s[0-9]+, v[0-9]+ 56
gcc.target/gcn/cond_umin_1.c scan-assembler-times \\tv_cmp_gt_i32\\tvcc,
s[0-9]+, v[0-9]+ 56
gcc.dg/tree-ssa/loop-bound-2.c scan-tree-dump-not ivopts "zero if "
The below test suites are passed for this patch.
1. The rv64gcv fully regression tests.
2. The x86 bootstrap tests.
3. The x86 fully regression tests.
4. The amdgcn test case as above.
gcc/ChangeLog:
* internal-fn.cc (type_strictly_matches_mode_p): Add handling
for vector bool type.
