[PATCH] D78977: [X86] Add x, t and g modifiers for inline asm

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

Amanieu added a comment.

They are not mentioned in the GCC documentation, but are documented in this <https://github.com/gcc-mirror/gcc/blob/f5edc76acac7bbadd8d1b00c4cc5994b2a088542/gcc/config/i386/i386.c#L12310> comment in the GCC code:

  If CODE is 'x', pretend the mode is V4SFmode.
  If CODE is 't', pretend the mode is V8SFmode.
  If CODE is 'g', pretend the mode is V16SFmode.

We need these modifiers for the new inline assembly support <https://github.com/Amanieu/rfcs/blob/inline-asm/text/0000-inline-asm.md#template-modifiers> in Rust.
