llvm dev - Jul 2015 - [LLVMdev] is it impossible to use the external llvm custom pass on windows?

Hello all,

Still, is it impossible to use the external llvm custom pass on windows?

I can build the 'mypass.dll' on windows using LLVM libraries. And, I use
these 2 way to use my pass.
clang.exe -Xclang -load -Xclang mypass.dll -c test.c
opt.exe -load -Xclang mypass.dll -mypass test.bc -o optimized_test.bc


But, Clang and opt didn't working well with my pass.


This mean, my pass can dump the llvm::Module in compilation time. and my
pass can dump that on Linux. but, my pass didn't print anything on Windows.

Additionally, i already built the LLVM and Clang on Windows using CMake.

To avoid confusing, i'm writing my source code.

#include <iostream>
using namespace std;

#include <llvm/Pass.h>
#include <llvm/IR/Module.h>
using namespace llvm;

class SampleIRModule : public llvm::ModulePass {
  public:
    static char ID;
    SampleIRModule() : llvm::ModulePass(ID) {}

    bool runOnModule(llvm::Module &M);
};

bool SampleIRModule::runOnModule(llvm::Module &M) {
    M.dump();
    return false;
}

char SampleIRModule::ID = 0;
static RegisterPass<SampleIRModule> X("SampleIRModule",
"SampleIRModule
Pass");


And,here is my build command on windows.
cl /EHsc -ID:\LLVM\llvm-3.4.2\build_nmake\output/include
-D_CRT_SECURE_NO_DEPRECATE -D_CRT_SECURE_NO_WARNINGS
-D_CRT_NONSTDC_NO_DEPRECATE -D_CRT_NONSTDC_NO_WARNINGS
-D_SCL_SECURE_NO_DEPRECATE -D_SCL_SECURE_NO_WARNINGS -wd4146 -wd4180
-wd4244 -wd4267 -wd4345 -wd4351 -wd4355 -wd4503 -wd4624 -wd4800 -wd4291
-w14062 -we4238 -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS
-D__STDC_LIMIT_MACROS -c testpass.cpp

cl /D_USRDLL /D_WINDLL testpass.obj /link /DLL /OUT:testpass.dll
D:\LLVM\llvm-3.4.2\build_nmake\output\lib\LLVMCore.lib ... (including other
LLVM libraries)

Thanks,

It would probably help if you explained what happens and how that is
different from what you expect...

i want to use the external LLVM pass that built in out-of-source on windows.
and, my sample pass just dump the llvm::Module during compiling some source
code.

i use this command.
opt.exe -load -Xclang mypass.dll -mypass test.bc -o optimized_test.bc

so, as my expect,
my pass should dump the llvm::Module of 'test.bc',
but, i couldn't see anything in my console.

one the other hand, i can see the result of dump() on Linux with same
source code (testpass.cpp)

Thanks,
Seok Hong
