Hi all, Is there a way to specify an attribute in a .ll file so that it will disable fp elim as if llc has been invoked with -disable-fp-elim on command line ?

I just enabled a new algorithm for computing live intervals that doesn't depend on LiveVariables. The goal is to get rid of the LiveVariables analysis completely, but unfortunately PHI elimination and the two-address pass still use LiveVariables for some optimizations. They don't require it, they work just fine without it at -O0. They use it to generate better code in some cases. The current pass order in the optimizing pipeline is: Live Variable Analysis Eliminate P...

How much of the work is done here? I'd be happy to do the phi elimination part, since I basically did that for StrongPhiElimination (RIP). IIRC you run into a lot of problems with NEON subregister defs, which might be fixed by your new direct LiveIntervals implementation.

(Sometime they are repeated three or four times). Clearly there is some make magic I don't understand here. Does anyone know what is going on?

Hi, everyone. I am new to llvm and I want to use C function “malloc" and “free" to do heap allocation, but It seems it is not a built-in function like ‘’printf” so I got an error “Unknown extern function”. I use ExecutionEngineer to run my main function and how should I do to make EE link the C library I want. Thanks.

I have this problem: google-perftools fails to detect stack for the code run under JIT called through C++ api from my program. It shows in profile like all program is one block with the name _init. I clearly do set the option NoFramePointerElim and I do see how it makes a difference in stack frame under gdb. When running some code in JIT in lli (with option -disable-fp-elim) google perftools is able to detect stack and build the correct profile. Problem only exists in linux/i386. On FreeBSD/amd64 google perftools detects stack fine f...
