[PATCH] D105067: [SystemZ] Emit .gnu_attribute for an externally visible vector abi.

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa added a comment.

I tried to move the handling of functions into computeInfo(), but found that it is not possible to know from a CGFunctionInfo if the function is externally visible or not. It does however seem like all vararg calls go through here (for normal functions only the declaration/definition is processed), which is fortunate as it happens that even a local vararg call should be regarded (the va_list could be passed to another global function potentially). I could therefore remove the new target hook I had added for the purpose of checking varargs.
