[LLVMdev] Problem with PTX assembly printing (NVPTX backend)

[nkavv at physics.auth.gr]

Hi all,

I'm trying to use the newly added (in LLVM 3.2) NVPTX backend for  
producing PTX (Parallel Thread eXecution) assembly from simple C  
programs.

While using llc with -march for mips and x86 works, -march=nvptx  
doesn't work. This seems reasonable since I can see that the  
libLLVMNVPTXAsmPrinter.a library is about 500 bytes (thus empty).  
However, the strange thing is that AsmPrinter code can be found in the  
NVPTX backend directory. I would expect that this code would be  
compiled to the corresponding assembly printing library.

Has anyone had similar problems with the NVPTX backend? Shouldn't this  
code be linked to the AsmPrinter library for NVPTX (already)?

BTW I've built LLVM with mingw (strange mixture of gcc-3.4.5 and  
g++-4.6.1). Native compilation, MIPS backend and other things that  
i've tested, all work properly.

Any help is appreciated.

Best regards,
Nikolaos Kavvadias
