Dear llvm-ers, I am trying to attach a customized metadata to llvm instructions. Let's say, I want to attach some number to each instruction. I am trying to use void Instruction::setMetadata(unsigned KindID, MDNode* Node) but I am not sure how to create a brand new instance of an MDNode. Do you have any code samples demonstrating how to do that? Due to some tool dependencies, I am using

...ng the instrument. Say, void HowManyTimeThisFunctionGetCalled(); Then you can insert a call to the function above while creating a LLVM function [1]. In that way, every time that LLVM function get called the function doing the instrument will be called. You might need to take a look on ${LLVM_SOURCE}/example/HowToUseJIT to get a feel on how to create a LLVM module, function and basic block.

Sorry to have to ask... I'm catching too much noise from dumps. I'm building LLVM 7.0 using release tarballs on OS X 10.5 PowerPC. I'm building out-of-tree mostly following https://llvm.org/docs/GettingStarted.html#getting-started-quickly-a-summary . Cmake gets this far and hangs: -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Looking

Hi, I am new to LLVM. I want to use LLVM to instrument codes, such as function calls and basic blocks. But I don't know where to start. I wonder if there are any example codes to show how to instrument codes in the IR level? Thanks. -- zhouxu -------------- next part -------------- An HTML attachment was scrubbed... URL:

I'm trying to build LLVM, CFE and RT from sources on an old PowerMac with OS X 10.5.
