For example, LLVM 3.4 generates very complicated code for the following IR. I am running on a Haswell processor. Is it because there is no alternative AVX/2 instructions for int64? The same thing

Sorry, I should ask the following: finds all the instructions of a function where a particular variable is defined? Lets consider the following code snippet: 1. void foo(){ 2. int a, b; 3. if(a > 10) 4. b = 10; 5. if(a<10) 6. b = 5; 7. cout << b; 8. } I would like to know the instructions where variable b can be be defined, i.e, in this case, the instructions 4 and 6.

Hi all, I am trying to use LLVM's AliasAnalysis pass, but from a standalone tool that uses llvm libraries. The following is the code snippet I am currently using. PassBuilder PB; auto mod_manager = ModuleAnalysisManager { }; PB.registerModuleAnalyses(mod_manager); AAResults& AAR = mod_manager.getResult<AAManager>(*M); But the code fails at .getResult with the following error:

Hello, I am building the SPEC 2006 Benchmark with Clang as the compiler. I have written a function pass in LLVM and I am trying to run that for SPEC by invoking the pass in the build options of SPEC. The build options of SPEC are in a *.cfg config file, which allows us to specify the choice of compiler while building SPEC. (https://www.spec.org/cpu2006/Docs/install-guide-unix.html) The pass
