It seems the scenario you pointed out are driver invocation use case. But when users invoke clang -cc1 not driver with -mabi=ext-abi/default, should we also check if the user specify `-target-feature +altivec` as well? For now, based on my observation, if invoking cc1 without `-target-feature +altivec` but with `-mabi=ext-abi` only like `// RUN: %clang_cc1 -mabi=vec-extabi -triple powerpc64-unknown-aix -emit-llvm %s -o - | FileCheck %s`, the error is `error: unknown type name 'vector'`. Should we explicitly say `-target-feature +altivec` is required as what we do for driver? ================ Comment at: clang/test/Driver/aix-vec-extabi.c:2 +// RUN: %clang -### -target powerpc-unknown-aix -S -maltivec -mabi=vec-extabi %s 2>&1 | \ +// RUN: FileCheck %s --check-prefix=CHECK + ---------------- minor: We can omit `--check-prefix=CHECK` ================ Comment at: llvm/include/llvm/Target/TargetOptions.h:179 + /// AIXExtendedAltivecABI - This flag returns true when -vec-extabi is + /// specified.
