llvm-mirror/test/CodeGen/Mips/largefr1.ll
Reed Kotler 434681ac07 When Mips16 frames grow large, the immediate field may exceed the maximum
allowed size for the instruction. This code uses RegScavenger to fix this.
We sometimes need 2 registers for Mips16 so we must handle things
differently than how register scavenger is normally used.
