LIR misses WL in CONDFUN
|Created on||Aug 31, 2012 23:04|
Created an attachment (id=929) source code to reproduce fault Recently, I loosened up the rules for WLPROP, in the hope of making a number of benchmarks run better, as well as making WLPROP work on CONDFUNs. However, I see today that some benchmarks, e.g., apex/ipbb/ipbb.sac, run a LOT slower, and the cause is a WL that is being WLPROP'd into a CONDFUN, but is not being LIR'd back out when AWLF/WLF fail to gobble up that WL. I tried tightening up the WLPROP rules to their previous state, with no luck. Running with -nowlprop avoids the problem, but that takes all the fun out of things. It may be that LIR never dealt with CONDFUNs. If so, that would certainly explain the problem. The failure definitely happens with Build #18200. I'll look into the problem over the weekend. After all, it IS Labor Day here, so I may as well be laboring.
