[Bug tree-optimization/42893] [4.3/4.4/4.5 Regression] Missed conditionally dead store elimination



------- Comment #6 from steven at gcc dot gnu dot org  2010-01-29 20:17 -------
I think the issue here is more that we should look for a way to optimize this
early on. I'm guessing it's one of the ce[123] passes that cleans this up for
you on your RISCy machine? IMHO it would be better even in your case to nuke
dumb code like this in GIMPLE (enabling other optimizations, etc.).
