Does wllvm support response files ?

[ym-xie]

Hello, I encountered an issue with response file handling in wllvm.

I have a source file hello.cpp and a response file res.rsp containing:

-c hello.cpp

I run the following command:

LLVM_COMPILER=clang wllvm++ @res.rsp

The compilation succeeds and an object file is generated, but I get the following warning:

WARNING: Did not recognize the compiler flag "@res.rsp"

Moreover, the resulting object file does not contain the llvm_bc section, meaning the bitcode is not embedded as expected.

It seems that wllvm does not expand or properly process the @response_file syntax.

No it doesn't. Neither does gllvm. But if it is just a compiler switch it can certainly just be added without too much trouble.
We will need a volunteer, because I don't code anymore.

Actually I don't think the wrappers can handle response files, since they internalize the calls to the compiler.
