similar to: [LLVMdev] alloca on Win32

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.

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

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

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

Hello, Scott. > Thanks for the help Jake and Anton. > Attached is a patch for DynamicLibrary.inc to fix alloca resolving. Thanks! I've slightly modified it not to break the things and have just commited. Could you please verify, that everything is ok? -- With best regards, Anton Korobeynikov.

Hello, I have a bytecode doing 64 bits division and on Mingw32/x86, lli complains it cannot resolve __udivdi3 when running it. Those symbols are all part of libgcc and all present in lli, but they cannot be found by SearchForAddressOfSymbol (not in any DLL). To workaround that, I explicitely define them in Win32/DynamicLibrary.inc if the current target is Mingw32 (patch attached). Anybody had

Hi When using lli on Win32 (vs.net-built), on any non-trivial code, I get the following abort ERROR: Program used external function '_alloca' which could not be resolved! Checking the assembly from llc, the first alloca call is to allocate local vars in _main. Is this just the state of the code at 2.0 when built with vs.net, or is there something that I've managed to mis-build

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.

We tested on 3.4.2 and 3.5.1. Later versions are slightly problematic to test since they don't compile with VS2010. Do you happen to know if it's fixed in one of the released versions, or if there is a workaround (chkstk?) or a bug report online? Thanks!

Hi @ll, compiler-rt implements (for example) the MSVC (really Windows) specific routines compiler-rt/lib/builtins/i386/chkstk.S and compiler-rt/lib/builtins/x86_64/chkstk.S as __chkstk_ms() See <http://msdn.microsoft.com/en-us/library/ms648426.aspx> Is there any special reason why compiler-rt doesn't implement other MSVC specific functions (alias builtins or "compiler

It also includes malloc.h, which is where mingw-w64 defines the alloca() macro, mapping it to gcc __builtin_alloca() or to msvcrt _alloca(). - -- O< ascii ribbon - stop html email! - www.asciiribbon.org -----BEGIN PGP SIGNATURE----- Version:

Hi All, we have an issue with our LLVM-based JIT compiler - executing the compiled code corrupts memory (and subsequently crashes) if we alloca more than 4k of variables (more than 511 8-byte ints). The same code works on Windows 7 (32 and 64 bit), Linux, MacOS. We compile LLVM and our program with Microsoft's Visual Studio 2010. Both debug and release builds are affected. The variables
