[LLVMdev] building llvm on Windows

[Razvan Aciu]

I tried to compile on Windows ( using the win32/llvm.sln in MSVC Express 
2008 ) the new 2.3 branch and here are the results:

1. I needed to copy the file Configure.exe.embed.manifest to 
Configure.exe.intermediate.manifest . This is a bug from the previous llvm 
release (2.2)

2. I copied the file SimplifyLibCalls.cpp from lib/Transforms/Scalar to 
lib/Transforms/IPO. I think the position of this file was updated but the 
MSVC project wasn't.

3. I put a "return SDOperand();" on X86ISelLowering.cpp, on function 
"SDOperand X86TargetLowering::LowerVAARG(SDOperand Op, SelectionDAG &DAG)" 
after "abort()", to make compiler happy to compile it.

4. I needed to give "Build Solution" more times, because there are some 
incorrect dependencies between projects and some of them expect results from 
the future builded ones.

After over 4500 warnings, I think most of them because of the automatically 
generated code, I succeded to compile almost all the projects, except opt 
and bugpoint. At these two I had an error:

error LNK2019: unresolved external symbol "class llvm::FunctionPass * 
__cdecl llvm::createLibCallAliasAnalysisPass(class llvm::LibCallInfo *)" 
(?createLibCallAliasAnalysisPass at llvm@@YAPAVFunctionPass at 1@PAVLibCallInfo at 1@@Z) 
referenced in function "public: __thiscall `anonymous 
namespace'::ForcePassLinking::ForcePassLinking(void)" 
(??0ForcePassLinking@?A0xd1580448@@QAE at XZ)

which I wasn't able to fix it.

I hope these will be fixed on the final 2.3 release so it can be compiled 
out of the box on MSVC Express 2008.

Now I'm checking on some Windows assemblers and other tools which can 
complete llvm to make it a full backend (with the final result an exe or dll 
file).

PS: I also tried to compile llvm 2.3 in MSYS using the latest MinGW with gcc 
4.3.0. This wasn't able to compile llvm at all because some errors like:
