Subject: [X86][FMA4] Remove isCommutable from FMA4 scalar intrinsics. They aren't commutable... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=1230bb045af12f8af42857c74937f59aa97b9c7f;p=llvm

[X86][FMA4] Remove isCommutable from FMA4 scalar intrinsics. They aren't commutable as operand 0 should pass its upper bits through to the output.
