Subject: x86_64 ABI: Make sure to pass vectors that we want to pass in memory
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=775e43b3bd47d9388608a57f7489982d3024fdc5;p=clang

x86_64 ABI: Make sure to pass vectors that we want to pass in memory
as byval. Otherwise LLVM will have its own opinion about where to put
things.

We now pass all gcc dg.compat tests on x86_64.
