Hi RamShankar, On top of Rafael mentioned ,Please check with lib/CodeGen/StrongPHIElimination.cpp and the papers like Budimlic, et al. Fast copy coalescing and live-range identification. // In Proceedings of the ACM SIGPLAN 2002 Conference on Programming Language // Design and Implementation (Berlin, Ge...

Hi, I am a newbie to llvm. I am wondering what approach is used when coming out of SSA form. I also appreciate pointers on where to look in the source code for this phase.

...for newest x86-64 there is an option -mprefer-avx128 for gcc, which helps over 256AVX for several cases.

I am wondering how O4 vs O3 do inlining. With O4 it looks like inlining is done first on each file and then at linking phase. Wouldn't it be a better alternative to delay inlining decisions until the link stage? Ram -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I have a test-case for which I seem to be getting incorrect information from basic-aa alias-analysis. Here it is: #include <stdio.h> #define ARR_SIZE 4 char c[ARR_SIZE]; char *pc[ARR_SIZE]; char **ppc = pc; int main() { pc[0] = &c[0]; pc[1] = &c[1]; pc[2] = &c[2]; pc[3] = &c[3]; printf(" ppc: %p\n" " pc : %p\n" " c :

Hi there! Greetings! I am wondering how I may be able get these annotations !noalias and !alias.scope to show up- I have a function with restrict added to the arguments but I do not see these intrinsics with clang -emit-llvm. Which pass inserts them? Best, Ram -------------- next part -------------- An HTML attachment was scrubbed... URL:

Perhaps we can parameterize the size of the vector while vectorizing @ llvm and fix up the loop iterators in a target specific pass. -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Hal Finkel Sent: Friday, October 05, 2012 8:30 PM To: Das, Dibyendu Cc: llvmdev at cs.uiuc.edu Mailing List Subject: Re: [LLVMdev] LLVM Loop

Hi, Anyone working to incorporate "real" profiles to lib/CodeGen/MachineBranchProbabilityInfo.cpp using profile-metadata-loader? We could use something similar to llvm's BranchProbabilityInfo.
