Subject: Big bug fix: getUsableUniRegAtMI needed to return values in arguments
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=705f95e0b7cb36b9f3786d4e8397f5226e4acd05;p=oota-llvm.git

Big bug fix: getUsableUniRegAtMI needed to return values in arguments
but did not pass the arguments by reference!
Also added a function to get a register class by ID.
