...e no other Analysis/Transforms which require this type of information? I looked at AESOP (http://aesop.ece.umd.edu/doc/aesop-white-paper.pdf) which implements an autoparallelization framework and it seems they would need to do similar checks, the page hosting the code is currently offline.

Hi Snehasish, thanks for writing up the proposal. As it stands today, path profiling still has serious scalability issue that prevents it from being usable by any optimization passes that may benefit from it. On the other hand, sampling based approach can still be promising. For instance, LBR can potentially...

...llelizationforllvm/building-the-dependence-graph Is there any existing implementation I can take a look at? It seems that the only the DependenceAnalysis::depends is only called in the dumpExampleDependence() function (checked using cscope). Is there no other module which uses this class?

The version we use internally is not performance oriented and will require refactoring. Here is a link to the draft document [1].

Hello, I'm trying to get the pointer to the first element of a string (so that I can pass it to a function). The string itself is a constant kept in a global variable. My end goal is to generate the IR for something like "puts("Hello World")"; I'm stuck on the parameter part of the call instruction. So far I have something like this: const std::string& str =

...p, early program termination, noreturn calls > How do you handle indirect calls? No special handling of indirect calls as path profiles are intra-procedural and control returns to same basic block after call in the general case. For the above mentioned cases, control may not return. Regards, Snehasish

I'm trying to link a program with LLVM on Linux. I've managed to take out the test files from 'llvm-config --libs' but now it's getting errors with missing symbols. The same program successfully links with the same version of LLVM (3.8) on Windows, so it's not a problem with the code per se, it's some kind of configuration issue. Any ideas? g++ -std=c++11
