...we can easily retrieve an LLVM instruction ID that uniquely identifies the instruction. In my case, I need to avoid using llvm::Instruction* directly. Given an 'inst' of type llvm::instruction*, is there some readily usable method as simple as "int id = inst->id( )"? Thanks.

...htly different from that of the source llvm/include/llvm/IR/BasicBlock.h In particular, llvm:: getModule(..) is included in the latter BasicBlock.h but not in the former BasicBlock.h. Am I misunderstanding something or is it an inconsistency LLVM developers will fix? Thanks in advance. Zhoulai -------------- next part -------------- An HTML attachment was scrubbed...

Hi Zhoulai, I am trying to modify "LoopUnrollPass" in llvm which produces multiple copies of loop equal to the loop unroll factor.Currently, using multicore architecture, say 3 for example and the execution goes like: for 3 cores if there are 9 iterations of loop core instruction 1...
