...m goal is definitely to go to aapcs. My question is more about bridging the gap until that is done and also providing compatibility with older binaries. Problem is that today Clang compiles FreeBSD code as apcs-gnu which is in my understanding wrong. Also clang fails to compile some C++ code as SizeType is defined as UnsignedLong for apcs-gnu (should be UnsignedInt).

Hi, Both NetBSD and FreeBSD seems to use older ATPCS ABI standard. As I can see it is not supported in LLVM. Seems that ATPCS is predecessor of AAPCS so I wonder how easy is to implement it in LLVM/Clang... Is it worth efforts? Any thoughts? Thanks, Damjan

We inject a typedef for size_t here: http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Sema/Sema.cpp?revision=218230&view=markup#l206 The typedef type is determined by calling getSizeType(). SizeType is (relevantly) calculated in two places: X86_64 http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Basic/Targets.cpp?revision=218666&view=markup#l3512 X86_32 http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Basic/Targets.cpp?revision=218666&view=markup#l3157 I don't see a...

Thx again Evan for the review. Here's a new patch for the JIT in itself. The major changes are: 1) A JITMemoryManager now has a flag saying "I require to know the size of what you want to emit" 2) DwarfJITEmitter is augmented with GetSize* functions 3) JITEmitter::startFunction checks if the JITMemoryManager requires to know the size. If so, it computes it and gives it through the

Dear all, Here's a new patch with Evan's comments (thx Evan!) and some cleanups. Now the (duplicated) exception handling code is in a new file: lib/ExecutionEngine/JIT/JITDwarfEmitter. This patch should work on linux/x86 and linux/ppc (tested). Nicolas -------------- next part -------------- An embedded and charset-unspecified text was scrubbed... Name: jit-exceptions.patch URL:

Hi, I'm working on bringing up complete coverage for a Gentoo x32 "desktop" system. I've been cooking up quite a few patches for various packages to push upstream, but right now, the biggest blocker is the lack of support for building with/codegen targeting x32 in llvm/clang. Since the x32 patches were sent last year, I see support code has landed in LLVM, and basic handling of

I believe that we provide a definition of size_t inside the compiler itself when clang is in MSVC compatibility mode.

Hi everyone, Here's a patch that enables exception handling when jitting. I've copy/pasted _many_code from lib/Codegen/DwarfWriter.cpp, so we may need to factorize it, but the functionality is there and I'm very happy with it :) lli should now be able to execute the output from llvm-gcc when using exceptions (the UnwindInst instruction is not involved in this patch). Just add the
