[LLVMdev] help with an error message using clang ?

[Christine Cheng]

Hi,

I am new to LLVM and clang and I would like to seek some professional help.
:)

I have been trying to compile some C code on a linux x86 computer for a
Sparc machine.

I used:

 clang -ccc-host-triple sparc-unknown-linux -ccc-clang-archs sparc -pthreads
-lm  -emit-llvm test.c -c -o -test.bc

The following error messages are produced:

/usr/include/pthread.h:665:6: error: 'regparm' is not valid on this platform
     __cleanup_fct_attribute;
     ^~~~~~~~~~~~~~~~~~~~~~~
In file included from TEST.C:46:
In file included from /usr/include/stdlib.h:320:
In file included from /usr/include/sys/types.h:271:

# define __cleanup_fct_attribute __attribute__ ((__regparm__ (1)))
                                                 ^            ~
In file included from TEST.C:65:

/usr/include/pthread.h:718:6: error: 'regparm' is not valid on this platform
     __cleanup_fct_attribute __attribute__ ((__noreturn__))
     ^~~~~~~~~~~~~~~~~~~~~~~

What causes the errors and how can I fix it?

Thanks a lot and have a nice weekend!

Best,
Christine
