Subject: * Coalesce the handy CALL* alias opcodes with the standard ones
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c661c3001ce27bd6c6a2035a3ad68d0530f00269;p=oota-llvm.git

* Coalesce the handy CALL* alias opcodes with the standard ones
* Congregate more branch-and-link opcodes together
* Mark FP, CPR, and special registers as volatile across calls
