Hey guys, Whys are there like 5 variants of CreateCall in IRBuilder<> with numbers appended to them? The only difference I can see is the number of arguments. Aren't C++ function overloads be suited for this? Félix

The only difference I can see is the number of arguments. Aren't C++ function overloads be suited for this? An overload could work, but this sort of API makes it more obvious which one you're trying to call and

I didn't it like the following: Value* str = builder.CreateGlobalStringPtr("str", ""); Value* data = builder.CreateLoad(a); //load a, b, or c Value* buf = builder.CreateLoad(buffer); builder.CreateCall3((value*)sprintf, buf, str, data); I want to test the sprintf function before adding the offset, but it didn't work.

...and all instructions in the function. When it sees a binary operator ("isa<BinaryOperator>(Instruction)") it needs to first insert a call just in front of the instruction (see an IRBuilder to do this; use "SetInsertPoint(Instruction)" to tell it where to add the call; use CreateCall3 to create the call). Then use replaceAllUsesWith to replace every use of the binary operator with the call you just created. Finally, delete the original instruction (eraseFromParent).

Hi, I am planning to extract every operation as function. eg. z=x+y; ==> z=func(x,y,op); I wish to write a custom definition of op. Which I would like to define in func. It would be really helpful if someone could suggest passes already available in llvm to look for or point some references how should one proceed on it. Is codeExtractor.cpp useful for this. I was also thinking of going like

I've built chromium with " -fprofile-instr-generate -fsanitize=address" -- the performance looks good! The file format from r198638 is indeed rudimentary. Do you already know how the real output format will look like? Just to summarize what I think is important: - minimal size on disk, minimal amount of files - minimal i/o while writing to disk, no lockf or some such -

Hi! Attached patches split init.trampoline into adjust.trampoline and init.trampoline, like in gcc. As mentioned in the previous mail, I've not made a documentation patch, since I'm not sure about what the documented semantics of llvm.adjust.trampoline should be.
