[PATCH] D57735: [X86] Add FPCW as a register and start using it as an implicit use on floating point instructions.

[Dimitry Andric via Phabricator via llvm-commits]

dim added a comment.

For what it's worth, this builds and tests correctly for me, and also appears to solve the test cases from bug 40206.



================
Comment at: lib/Target/X86/X86RegisterInfo.td:290
 // Floating-point status word
 def FPSW : X86Reg<"fpsw", 0>;
 
----------------
It looks like you recently renamed this to `fpsr`, so this must be rebased.
