Hi, Because of this "return true" not every block was visited and only one ExitBB was found (instead of two). Thus, loop was optimized as a trivial one, which was wrong. -Jakub On Nov 24, 2009, at 2:28 PM, Dan Gohman wrote: > Hello, > > I haven't studied this in detail, but at a first look this makes the > code inconsistent with the associated comments.

Hello, Simply removing that "return true" causes the code to search blocks outside of loops for side effects. That's not what the code is supposed to do.

Hello, Yeah, sorry, you are right. My new idea is that only one ExitBB is found because Header ("for.body") is already marked as visited. I'm pretty sure that someone had a good reason to do this that way, but I can't find it out :) Dan, can you look at this patch? Thanks -Jakub -------------- next part -------------- A non-text attachment was scrubbed... Name:

Analyzing a compilers behavior and timings is an important tool to track code size and compile time regressions. One of the tools we would like to use are Statistic variable (llvm/include/ADT/Statistic.h). However today I cannot enable them in release builds without a performance hits because the lazy initialisation present forces a memory fence on every single increment of the statistic variable.

Hello, I haven't studied this in detail, but at a first look this makes the code inconsistent with the associated comments. Why should the code continue recursing past a loop exit?

I have written a function to emulate minitab's QQ plotting output (with SW test and AD test results on the graph): mtab.norm<-function(x) { library(nortest) library(lattice) x<-as.numeric(x) x<-as.vector(x) plot.ht<-4.6 plot.wd<-4.6 pt.ht=plot.ht/5 txt.sz<-(plot.ht/7.5) X11(width=plot.wd, height=plot.ht, bg='gray96') qqplot(x, pch=16, cex=pt.ht,

Given that LLVM has so many auto-registration systems (cl::opt, target registry, pass registry, statistics, I'm sure there's more), maybe we should spend the time to build an auto-registration system that doesn't involve static constructors? It needs custom code for every supported object file format, and is hard to get right when DSOs are involved, but in the long run it's

Hello, This patch fixes PR4174. Two test-cases included: original one from bugzilla and a little bit complicated made be myself. It seems that LoopIndexSplit doesn't handle some cases, I'll try to send some patch this week. Regards -- Jakub Staszak -------------- next part -------------- A non-text attachment was scrubbed...

Looks good. Pl. apply.

Hello, I was wondering about the case below. I tried to find any information in C standard, but I found nothing. In this case, variable "i" is uninitialized, but it is the _same_ value passed as an argument, so only of "a" or "b" should be printed. What I found is that with -O2: LLVM (trunk) prints both "a" and "b" GCC (4.2) prints both

Hi Kuba, Thanks for your feedback. I have made some improvements on the proposal according to your feedback and clarify something on the time availability. I left comments on the questions you asked in the doc. Please check it out.

Is there any reason that we don't have isLoopSimplifyForm method in LoopBase? Can I move it there? -Kuba -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20110728/95b007e3/attachment.html>
