The test looks much better now and makes a lot more sense to me. I still think we are missing out on opportunities to strengthen our testing. The two RUN lines are checking the cases where we have native 16-bit types or not. There are many CHECKS here that are only being validated when 16-bit types are enabled, but are fully valid when 16-bit types are not enabled. For example, ``` // CHECK: %dx.dot = mul i32 %0, %1 // CHECK: ret i32 %dx.dot int test_dot_int ( int p0, int p1 ) { return dot ( p0, p1 ); } ``` is equally valid whether 16-bit types are enabled or not, but we only check it when 16-bit types are enabled. If we used 3 different check prefixes (`CHECK`, `NO_HALF`, `NATIVE_HALF`) then it would give better coverage and make it clearer where we expect the differences to be. https://github.com/llvm/llvm-project/pull/81190 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
