[llvm-commits] CVS: llvm/test/Regression/CodeGen/Alpha/ctlz_e.ll

[Andrew Lenharth]

Changes in directory llvm/test/Regression/CodeGen/Alpha:

ctlz_e.ll added (r1.1)
---
Log message:

Legalize for CTLZ generates a ctpop, but this ctpop is not expanded.
This is bad.  It is generated if you are ctlz a type that is not 
legal for the arch (aka ctlz of bytes on alpha legalize fine).
