Hi, I would like to run the -O1 pass sequence followed by -reg2mem from an out of tree project which uses llvm. I am using the following code snippet to do so but in some cases, my method is also vectorising the code, which doesn't happen when running the same sequence(-S -O1 -reg2mem) through opt. Can someone please help me find what I am missing? Thanks, Akash. *

Talked to Eric Fri and he suggested that this might be the first of several places where we want behavior of LTO compiles to diverge from normal -O2 compiles. So for now I have implemented this such that we pass down -flto to the -cc1 job, and that gets propagated as a code gen option and into the PassManagerBuilder. I have left the current logic translating -flto to the -emit-llvm-bc option,

Simplifycfg doesn't get run by default even with -O3, but 'opt -simplifycfg' can do it. I'm looking to add this functionality to an optimizer program that uses the llvm libraries. What's the best way to do this? I don't really mind whether it becomes available as a command line option as in opt, or I need to hardcode it as always on. To make it available as a command line

Okay, as far as I can see looking through the output of that, the empty block isn't created near the end, it exists at the start and never goes away.

Hi All, I have centos 7. Apache and php are installed. CGI runs fine - php does not seem to run. I have the /etc/httpd/conf.d/php.conf file php.conf # # Cause the PHP interpreter to handle files with a .php extension. # <FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch> # # Allow php to handle Multiviews # AddType text/html .php # # Add index.php to the list of

Hi, In my work applying -flto to Chrome, I need to set some names to be skipped by the InternalizePass; otherwise, the linking stage fails (i.e., when building the chrome binary). In the past, I had a tiny patch that I hadn't submitted to LLVM: it was something like: Index: Internalize.cpp =================================================================== --- Internalize.cpp (revision

Yes, that is what I was thinking. Should I report it as a bug?

Hi, This is Ariel from the Rust team again. I am having another pass ordering issue. Looking at the pass manager at https://github.com/llvm-mirror/llvm/blob/7034870f30320d6fbc74effff539d946018cd00a/lib/Transforms/IPO/PassManagerBuilder.cpp (the early SimplifyCfg now doesn't sink stores anymore! I can't wait until I can get to use that in rustc!) I find that the loop optimization group

Hi, If we add multiple loop passes to the pass manager in PassManagerBuilder.cpp consecutively without any func/module pass in between, I used to think they would belong to the same loop pass manager. But it does not seem to be the case. For example for this code snippet PM.add(createIndVarSimplifyPass()); // Canonicalize indvars MPM.add(createLoopIdiomPass()); //
