I'm building a StructType without a body using StructType *StructType::create(LLVMContext &Context, StringRef Name); and then later adding a body to with setBody(). It starts of isOpaque() == true, and isSized() == false, and after I add the body, isOpaque() == false, but isSized() is still false. If I create a StructType using StructType * StructType ::create(LLVMContext &Context, ArrayRef<Type*> Elements, StringRef Name,...

Dear all I am trying to get the size of an LLVM pointer type. getPrimitiveSizeInBits() returns 0 for it and the documentation for isSized() suggest to use TargetData. I figured out from Kaleidoscope example that one can get a pointer to TagetData object through the execution engine but it seems to be an overkill. What is the right way to do it?

It starts of isOpaque() == true, and isSized() == false, and after I add the body, isOpaque() == false, but isSized() is still false. this is the standard way of making a struct type, so I suspect you made a mistake such as adding an opaque field to the struct (this will stop it from having a size).

...ions ( and Values at the same time). I can do this by extracting type of the Values, but if I have still some unused instructions , I can't keep track on them. I try to convert them to Value and get the type or simply get the type of instruction, but have the following error: Assertion `Ty->isSized() && "Cannot getTypeInfo() on a type that is unsized!"' failed. This is second or instruction: %1 = or i32 10, 20 %2 = or i32 %1, 10 ret i32 %1 What can be done in this case? -------------- next part -------------- An HTML attachment was scrubbed...

TargetData is an LLVM pass. If you're writing an LLVM pass, jus...

I think I found it. In InstCombiner::ComputeMaskedBits we have the following lines: if (GlobalValue *GV = dyn_cast<GlobalValue>(V)) { unsigned Align = GV->getAlignment(); if (Align == 0 && TD && GV->getType()->getElementType()->isSized()) Align = TD->getPrefTypeAlignment(GV->getType()->getElementType()); It assumes that global values are always optimally aligned. I think this is incorrect and the bottom two lines should be removed. However, I do think it's useful to specify the alignment at the time o...

Hi Chandler, > void > foo () { > float x __attribute__ ((mode (XF))); > } nice reduction. I don't see any problem on x86-32, and I don't have access to an x86-64 box right now. Can you please open a PR for this, and also run in the debugger. When you hit the abort, use "up" to go up a stack frame or two or three, and print out the gcc types [use: call

Hi all, The InstructionCombining pass causes alignment of globals to be ignored. I've attached a replacement of Fibonacci.cpp which reproduces this (I used 2.3 release). Here's the x86 code it produces: 03C20019 movaps xmm0,xmmword ptr ds:[164E799h] 03C20020 mulps xmm0,xmmword ptr ds:[164E79Ah] 03C20027 movaps xmmword ptr ds:[164E799h],xmm0 03C2002E

...to get the size of a global variable. That is, if the C source looks like: int a[3]; then printing the description of the type of this global looks like: [3 x i32]* Is there some nice way to get "3 words" or "12 bytes" from the above example? Let's assume I do some "isSized" check. It looks like there is a getPrimitiveSizeInBits, but nothing for composite types. Maybe I am missing something. Thanks, Scott
