[PATCH] D134717: [Clang][AArch64] Fix va_arg with -mgeneral-regs-only

[Amanieu d'Antras via Phabricator via cfe-commits]

Amanieu added a comment.

Currently using Clang with -mgeneral-regs-only generates perfectly fine soft-float AArch64, with the except of the va_arg() implementation which is fixed here. In fact Rust even has a aarch64-unknown-none-softfloat which relies on this behavior in LLVM. I believe this behavior is *more* useful than GCC's which simply rejects float/double types, and it makes sense to keep it and fix it.
