similar to: [LLVMdev] Implementing optimization levels -03

Hi, I want to see any warning that are produced when I build llvm (in particular, those in code I'm writing). Before I do something quick and dirty with tee and grep, I was wondering if there was already something available to, for example, reprint warnings after a build completes? Thanks, --Paul

I have a whole slew of questions about optimization passes. Answers to any or all would be extremely helpful: How important are doInitialization/doFinalization? I can't detect any difference if I use them or not. Why does the function pass manager have doInitialization/doFinalization, but the global pass manager doesn't? If I am applying the function passes to many functions, do I

Hi Paul, That should be easy enough, because the LLVM build has no warnings in it! Some of us build with -Werror, and even with those of us that don't warnings are not tolerated. You're already seeing all the warnings that are coming out of the build :) Cheers, James ________________________________________ From: llvmdev-bounces at cs.uiuc.edu [llvmdev-bounces at cs.uiuc.edu] On Behalf

The only two examples of pass sets I can find are the Kaleidoscope tutorial and StandardPasses.h (corresponding, I assume, to what llvm-gcc does). Just looking at the two of these, some

Good point. The same argument seems to apply to copy() too so I suppose it depends how strict we want to be about it.

Transforming this to an fsub could change the value stored on platforms that implement negates using arithmetic instead of with bitmath (such as ours) I think it's probably safe for IEEE754-2008 conformant platforms because negation was clarified to be a non-arithmetic bit flip that cannot cause exceptions in that specification. However, I'm sure

Look I have written a PRE pass. opt is running that pass. I have included my pass name there in include/llvm/Support/StandardPasses.h file. To do that, I have got some error. Because it also requires the definition of the pass in some other file also. I observed how gvn pre pass is added to the pass list. I had followed the same way, but failed. Cna you kindly tell what needs to be done in this

Hi all, we're working on compile-time instrumentation for ThreadSanitizer (a data race detector, see http://code.google.com/p/data-race-test and http://code.google.com/p/data-race-test/wiki/CompileTimeInstrumentation), which is implemented as an opt plugin that is ran for each client C/C++ module we compile. To build a binary consisting of several modules the following steps are performed:

Summary: We need to find a reviewer for our implementation of Ball-Laurus path profiling. It is well known that path profiling generates more precise information about a program's behaviour than edge profiling. We are conducting a research project with the goal of developing a methodology to make feedback-directed optimization (FDO) more sound. We are developing combined profiles that enable
