[LLVMdev] Building LLVM under Mingw. Part I: tools-only

[Anton Korobeynikov]

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)

1.2. Binutils 2.16.91 20060119 from mingw.org site.
$ ld --version
GNU ld version 2.16.91 20060119

1.3. GNU Make 3.79.1 taken from msys distribution.

$ make --version

1.4. Bison 1.875 from GNUWin32 project

$ bison --version
bison (GNU Bison) 1.875

1.5 Flex 2.5.4 from GNUWin32 project.


2. Patching.

2.1. Libraries
Add "LIBS+= -lpsapi -limagehlp" to each makefile (AFTER
Makefile.common inclusion) building some tool (burg, tablegen, ll*),
since gcc doesn't support vcpp style #pragma's of form:
 #pragma comment(lib, "dbghelp.lib")

2.2 CopyFile
Patch lib/System/Win32/Path.inc in such way, that declaration of
CopyFile will look like:

void
CopyFile(const sys::Path &Dest, const sys::Path &Src) {

2.3 X86 stuff
Patch lib/Target/X86/X86SubTarget.cpp & X86JITInfo.cpp in such way:

X86SubTarget.cpp:
#if defined(__CYGWIN__) || defined(__MINGW32__)
    TargetType = isCygwin;
#elif defined(__APPLE__)
    TargetType = isDarwin;
#elif defined(_WIN32)
    TargetType = isWindows;
#endif

X86JITInfo.cpp:
#if defined(__CYGWIN__) || defined(__APPLE__) || defined(__MINGW32__)
    ".globl _X86CompilationCallback\n"
  "_X86CompilationCallback:\n"
#else
...
#if defined(__CYGWIN__) || defined(__APPLE__) || defined(__MINGW32__)
    "call _X86CompilationCallback2\n"
#else

2.4 alarm()'s in Sparc backend

Remove from lib/Target/SparcV9/ModuloScheduling/ModuloScheduling.cpp
all calls to alarm().

3. That's all

This should be enough to configure and build LLVM in tools-only mode.
Unfortunately, ld crashed while building llc, I'm currently
investigating this problem. Also, I'm working on building gcc backend.
The results will follow.
