Hi all. In the beginning of this method I see the next: for (unsigned i = 0, e = AttrGrps.size(); i != e; ++i) { AttributeSet AS = AttrGrps[i]; for (unsigned i = 0, e = AS.getNumSlots(); i != e; ++i) { AttributeSet A = AS.getSlotAttributes(i); Record.push_back(VE.getAttributeGroupID(A)); Record.push_back(AS.getSlotIndex(i)); for (AttributeSet::iterator I = AS.begin(0), E = AS.end(0); ... Why 'begin(0)'? Shouldn't it be 'AS.b...

I fell over this issue yesterday myself with lots of asserts being thrown. I think the issue is in lib/IR/AsmWriter.cpp:1618 in the function AssemblyWriter::printFunction(const Function *F) Looking at the code I think the 2nd for loop should be preceded by the test ... if (Idx < AS.getNumSlots()) Not sure why it doesn't fail on other platforms as it looks like it should be a genuine issue on all platform. That change significantly reduced the failures on my Windows build. Keith -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu...

In a debug build you should get a stack trace by default, which would be helpful here. I can try to repro later today, but I'm not surprised there are issues because most people I know stick with 32-bit builds even on 64-bit Windows.

LLVM's Attribute APIs need an overhaul. Current problems ================ First, testing for an attribute on an Argument is slow. llvm::AttributeSet::getAttributes(int) consumed 2% of cycles while optimizing llc during LTO. Our mid-level optimizations are constantly asking if a given argument has some attribute (nonnull, dereferencable, etc), and this is currently linear in the size of the
