saiislam updated this revision to Diff 398897.
saiislam added a comment.
1. Used a common diagnostic warning `warn_unknown_declare_variant_isa_trait`
for ParseOpenMP and SemaOpenMP for decalre variant and metadirectives.
2. Split lit codegen tests into two files, one requiring amdgpu-registered
target and another for host only.
3. Added warning message lit test at an appropriate place.
