In general, the whole windows64 support is missed mainly due to crazy calling convetion invented by Microsoft. So, all calls from code being JITed to external functions will be clearly broken (if they

Well, anyway stubs are definitely wrong from windows64 and this should be fixed, otherwise funny stuff can happen from time to

Hello, Chuck > Would my life be made fantastically simpler if I were using a different > calling convention for my callback functions on x64 running on Windows? Yes, surely. You can still use 'normal' x86-64 CC if you don't want to call any external functions from code being JITed. Also note a Win64 fixme in the X86CompilationCallback2 function, this can be your case. I think

Well, as currently we don't have windows64 support in FE correct (non-windows) CC will be set automatically. -- WBR, Anton Korobeynikov

Hey Evan, At the point of the instructions you suggested I step through, X86ISelLowering has this state: - this 0x00000000005fe728 {VarArgsFrameIndex=-842150451 RegSaveFrameIndex=-842150451 VarArgsGPOffset=3452816845 ...} llvm::X86TargetLowering * const + llvm::TargetLowering {TM={...} TD=0x00000000008edac0

Hola LLVMers, I'm debugging through some strangeness that I'm seeing on X64 on windows with LLVM2.2. I had to change the code so that it would engage the x64 target machine on windows builds, but I've otherwise left LLVM 2.2 alone. The basic idea is that I've got a function bar which is compiled by VStudio and I'm creating another function foo via LLVM JIT which is going

This is pretty ugly, but the names of this functions differs

Hi Thanks for the info, it led to the source of the error I was having. I was using llvm-gcc binaries (built with mingw I guess) to compile a .c file that is my language runtime, llvm-link'ing that with my frontend's .ll, and using an vcpp-built lli to run the resulting bytecode. This caused the special case in X86RegisterInfo::emitPrologue for "main" to try to align the stack

The alloca hook is in lib\System\Win32\DynamicLibrary.inc all the way at the bottom. You'll see a __MING32__ #ifdef around the definition. You just have to implement those methods and it'll work just fine.

Hello, Everyone. Now I have some spare time and I've decided to build LLVM on Mingw. I've grab the latest 1.7 release (not CVS snapshot). Here are some issues fixed during the build. Now I'm preparing gcc build. So, I think, there will some other "parts" 1. Prerequisites 1.1 GCC 3.4.5 from mingw.org site. $ gcc --version gcc.exe (GCC) 3.4.5 (mingw special) Copyright (C)

Hi Evan > It looks fine to me. Anton, does it look ok to you? This looks ok for me modulo win64+vcpp issues, which I mentioned in the PR (external .asm files). The anonymous namespace thing should be guarded by define (either _M_AMD64 or X86_64_JIT && _MSC_VER, I'd prefer the latter). -- With best regards, Anton Korobeynikov.

It looks fine to me. Anton, does it look ok to you?

This is only the tip of the iceberg, unfortunately. There are others more severe ABI incompatibilities. -- WBR, Anton Korobeynikov

Hello, Chuck. > "Error, Program used external function _alloca which could not be resolved!" I think the problem is the same. But... Cygwin is handled separately, because it's really more unix-like, that e.g. mingw32. Even more, it uses "unix" variant of libSystem. Probably you have to introduce the same hook (as for mingw32 / vcpp) there. -- With best regards, Anton

Hi everybody, We have FLAC supported for input/output in REAPER (http://www.reaper.fm), and the problem is that when writing 24 bit FLAC files, the data isn't compressed (i.e. the FLAC is slightly larger than if it was writing to .WAV). The files play back fine, however, and 16 bit mode works great. We're using flac-1.1.2, built on win32 with MSVC6 w/ SP5 + VCPP, and NASM version 0.98.39

Hi, Nicholas > Anyway, my questions are as follows: Is x64 JIT on Windows supposed to work currently?

Yes. > And if so, is there a time-line or roadmap for achieving such a goal? Not yet, this will require some huge changes in generic CC handling code. I hope,
