There was a problem hiding this comment.
Okay so this seemed slightly sus, but it was added in #44066 and looks right. Original comment was
For struct FloatOne { double x; }, it appears that MSVC passes the parameter in RCX and returns in RAX, but mingw-gcc passes the parameter and return value both in XMM0. Mingw-clang does the same as MSVC, so I think this is a GCC bug.
reported to gcc in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82028 marked as dupe of https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85667.

Feel free to r=me unless u want to adjust the comment. |
While it shares more than zero code with the SysV x86-32 ABI impl, there is no particular reason to organize wildly different ABIs using if-else in the same function.
