Subject: CodeGen: add sensible defaults for the ISD::FROUND operation
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=483b0e996c4d7b72cffd3ceacc0636758749940e;p=oota-llvm.git

CodeGen: add sensible defaults for the ISD::FROUND operation

Some exotic types didn't know how to handle FROUND, which ARM64 uses.
