Hi I just had some code which filtered via isa<UnaryInstruction>. Strangely enough not only the instructions which inherited UnaryInstructions but also: GetElemPtrInst, SwitchInst , xor, shl where true on isa<UnaryInstruction>. While the first two seem to be at least semantically ok the latter seem somehow wrong? I didn't find the place where the isa_impl templates where resolved to the real thing, so i didn't dare to fi...

Hi folk, I get the following stack trace and do have any clue how to fix the problem. 0 opt 0x087ecc99 1 opt 0x087ed265 2 0xb7f6a400 __kernel_sigreturn + 0 3 opt 0x086d4198 llvm::LeakDetector::addGarbageObject(llvm::Value const*) + 29 4 opt 0x0872945f llvm::Instruction::Instruction(llvm::Type const*, unsigned int,

Hello, I have a problem of generating a load instruction. The LLVM bytecode is: ------------------------ entry: ... %2 = call i32 (...)* @atoi(i8*%1) nounwind /*<- Insertpos*/ ... -- bb1: .. %5 = icmp sgt i32 %2, %i.0 ... ----------------- Now I have pb: pointer to the Value object of *%2* of bb1. Here, I want to generate a load instruction and I did it as: new LoadInst(pb,

Hi all, I'm having a bit of trouble with the online doxygen documentation. As far is I know, it should reflect current svn trunk. However, it seems out of date. For example, the ExtractValueInst [1] is not a UnaryInstruction yet and still takes Value* as indices. To add to the confusing, the mainpage [2] says it is documentation version "2.1svn" which seems even more weird. What

Hi all, I am having some some trouble with LLVM 3.8... I built it with GCC 4.8.2 with cmake and no special CXX/C flags. That means in case of GCC that RTTI is switched on, I believe. However, building my MCJIT application against the just built LLVM and linking results in: libqdp.a(qdp_llvm.o):(.rodata._ZTIN4llvm8FCmpInstE[_ZTIN4llvm8FCmpInstE]+0x10): undefined reference to `typeinfo for

Hi, I am trying to figure out the best way to add some extra metadata to the store and load llvm-ir instructions: The metadata content is a 'Value*' expression representing a side channel, containing dependency information that is used to help the Scoped Alias Analysis. Optimizations that don't know about this side channel can safely drop it, where the only effect would be on the

Hi Dan, Unfortunately, no. I can feed you with some speculation, though, see below. The reason why I cannot do measurements (at the moment) is that - I have no experience with
