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

Hi For .LL like: define void @Func() { %var1 = alloca double store double 0x40bb580000000000, double* %var1 ret void } ppc32 output is: ... lis 3, 16571 ori 3, 3, 22528 li 4, 0 stw 3, 8(1) stw 4, 12(1) ... I'm using the PPC backend's output as the "bytecode" for an interpreter that I would like to be able to run

Hello, Scott. > Is that generally dangerous, or should it be OK? Well, in general, it's dangerous, because you should probe the stack on windows, if you'll allocate more than 4k. This is needed to let guard pages be allocated in proper order. So, you can see random crashes here and there now :) For example: try to allocate big array (>4k of size) and touch its last element (this

Hi Our front end is written in a CLR language, and we're currently interacting with the middle/back-end by writing out .ll files. This was convenient to get started with, but they're getting to a "huge and unwieldy" stage now. I was wondering if anyone's attempted writing proxy/wrapper C++/CLI classes so that the IR API can be used directly from managed languages. Any

Hi I'm working on switching from generating textual .ll files in my front end to using the llvm-c IR builder API instead. One thing that I really miss is that when I dump() to a .ll file for debugging, the type names are worse than useless, because many types have been merged with unrelated types that happen to have the same shape. This becomes very confusing when trying to map back to the

Hi I'm using the llvm-c wrapper, and trying to build some recursive types (using released 2.3). I get an assert on trying to create a second opaque pointer type after refining a first. The first time through creating an opaque pointer type, a new type is created and returned from PointerType::get, but the second time, ValueType (the opaque type) is found in the PointerTypes map, which seems

Take a look at this page.

Hi Is there any rationale written down for why integer types don't carry (perhaps optional) signs somewhere? I feel like I might have read it somewhere before (and I see that it used to exist pre 2.0), but I can't find anything now. Relatedly, is there a reasonable way to attach user-data to a type or something? It feels very cumbersome to have to wrap all values and types in my front

I run into this problem as well. However, given the way LLVM represents types and their names, there is not an easy solution to this problem. I don't know of any real workaround that will not change the semantics of the code. - Daniel On Mon, Oct 27, 2008 at 4:42 PM, Scott Graham <scott.llvm at h4ck3r.net> wrote: > Hi > > I'm working on switching from generating textual

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

Your install dir has a whitespace.

I replaced all instances of "$(Platform)" with "x64" for the x64 .props file and it still fails, so it looks like that guess was wrong as well.

Open the file toolset-vs2013.props and you'll understand what's happening and where the path is set. It tries to fetch the LLVM installation path from the Windows registry. Just fix this (maybe editing your registry or editing the .props file, whatever suits you best).

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().
