Subject: Implement SPselectfcc for i64 operands.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=89db6732fbd987a33751f4aff01b8e4b0a630d91;p=oota-llvm.git

Implement SPselectfcc for i64 operands.

Also clean up the arguments to all the MOVCC instructions so the
operands always are (true-val, false-val, cond-code).

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182221 91177308-0d34-0410-b5e6-96231b3b80d8
