Subject: [mips] Fix floating point branch, comparison, and conditional move instructions
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=9955cb931b287bec91313a4b185fa965fb71f559;p=oota-llvm.git

[mips] Fix floating point branch, comparison, and conditional move instructions
to have register FCC0 (the first floating point condition code register) in
their Uses/Defs list.

No intended functionality change.
