llvm dev - Oct 2011 - [LLVMdev] Compile llvm-gcc fortran backend using mingw

PS: A more convincing (IMO) argument against dragonegg is that it doesn't
work on windows.  That's because the gcc plugin architecture doesn't
work
on windows.  Takumi has been thinking about this and has been enable to
get dragonegg to work on windows anyway using some clever tricks.

Interesting, thanks for the information. Is that already available 
somewhere, or are there any plans to release it along with LLVM 3.0?

I don't use Windows much myself, but some Pure users and many of my 
students do. Pure relies on LLVM-capable compilers for its C/C++/Fortran 
inlining capabilities, so being able to just point Windows users to a 
binary llvm-gcc package to make that work is very convenient. Of course 
we can stick to the latest llvm-gcc 4.2 on Windows for a while, but if 
there's a dragonegg version that works there then I'd certainly like to 
give that a whirl some time.

Not yet. I have to do;

1) Submit my patches to upstream gcc.
2) Let patches applied by distributors (mingw, tdm, and cygwin)

X) Then, I could apply my tweaks :D

GCC is required;

1) cc1*.exe should export (dllexport) available symbols.
2) People could use the distro "--enable-plugins and
symbol-exported-cc1.exe"

With my experiments, dragonegg can run on cygwin.
Cygwin has its dlopen and dlsym.
For mingw, I have to implement their emulator. (It would not be hard)
Seek llvmdev with "dragonegg cygwin Takumi" ;)

Unfortunately, I have little time to work on. Please be patient.

Thank you, ...Takumi

Nice to be called "Pure" :-) especially with capital letter.

MinGW binaries for llvm-gcc don't have Fortran frontend.
That is why I needed to re-compile llvm-gcc at first place.
