[PATCH] D141074: Avoid converting 64-bit integers to floating point using x87 on Windows

[icedrocket via Phabricator via llvm-commits]

icedrocket updated this revision to Diff 486923.
icedrocket added a comment.

Add the `pc80` option. There may be other suitable candidate names for this option, but I used the name from Intel ICC. The current implementation only applies to conversions from 64-bit integers to floating point.
