Not 100% if this is an LLVM question or a CLang question, though I expect LLVM. On Linux, if I pass '-fsave-optimization-record' to 'clang', then it produces a '*.opt.yaml' file. However, the same thing run on Windows using 'clang' built with VS2015 silently ignores this option. Is this a bug or is it intentional? And if it is intentional, how can I configure and build on W...

Is there any way to find if a optimization pass has passed in opt? In clang -fsave-optimzization-record would tell if particular optimization pass has applied or failed. Is there similar functionality in opt? Regards, Nethish. -------------- next part -------------- An HTML attachment was scrubbed...

I want to know all the optimization applied by the passes. I found two options in clang 1. -fsave-optimization-record 2. -Rpass-analysis=... However, they have nothing to do with the interaction btw IR files(.ll) Is there any tool that records all optimizations on IR file? -------------- next part -------------- An HTML attachment was scrubbed...

Hi, I'm new to llvm and am trying to run benchmarks from the test-suite using lnt to check loop-vectorization for various benchmarks. Test are compiling and executing fine, but I am not getting optimization remarks while using flags like -Rpass-missed=loop-vectorize and -Rpass-analysis=loop-vectorize I've tried running it like this: lnt runtest test-suite --sandbox SANDBOX --cc

Dear everyone, We're a couple of release candidates into the process, and the release notes are not in very good shape: http://prereleases.llvm.org/5.0.0/#rc2 If you committed anything noteworthy in the last six months, or saw someone else do it, please consider adding it to the release notes. People do read them. If you're responsible for a specific CPU target, please help give those

I would like to be able to emit a list of functions by name and their fixed stack reservation size information, so that a programmer can gauge how much stack they are likely to need in tightly constrained embedded systems. Despite the rich number of options, the only option I can find that is even relatively close is: -warn-stack-size=<uint> Is there some existing way of getting this

Hello all, During the compilation process, LLVM automatically derives various attributes about functions and values (for example that a pointer is nonnull, a function is constant, etc) that are used within a translation unit. I propose adding a pass to LLVM that allows front-ends to output derived attributes. Such a pass would be useful both for developers and end users to debug programs,

Hi, This series integrate the processor.h header. There are a lot of things that are deeply architectural differences between architectures, but I've done my best to come to a settlement. With this series, I am very close to have selectable paravirt for x86_64, It applies ontop of today's x86 git, mm branch.

Dear LLVM community, How to find out which optimization passes have been performed and which passes have failed?
