Changes in directory llvm/lib/Target/PowerPC:
PPC32ISelPattern.cpp updated: 1.161 -> 1.162
---
Log message:
Remove some dead cases.
Emit the indcall sequence as:
mtctr inreg
mr R12, inreg
btctr
If inreg and R12 aren't coallesced, this reduces the odds of having the mtctr
and btctr in the same dispatch group. :)
