Herald added a project: clang.

This is a small - but signifcant - update to the original changeset.

What's new in this update:

${top_srcdir}/lib/Frontend/CompilerInvocation.cpp:

When -fveclib=SLEEF was passed on compile-line, neither clang nor LLVM emit any warnings if SLEEF is not supported on the Target architecture. SLEEF is currently supported only on AArch64. So, for other ISA's, -fveclib=SLEEF would be quietly ignored, without any hints.

This new version of the changeset adds a diagnostic if -fveclib=SLEEF is called on an ISA that doesn't (yet) support SLEEF.
