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 TEST.C:65:
/usr/include/pthread.h:677:3: error: 'regparm' is not valid on this

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

You'll need to somehow use headers from your target Sparc machine to make things work properly; you can probably just copy them, and use -nostdinc plus some -I flags to make clang use them. -Eli
Hi Eli, Thanks for the reply. Indeed there is solaris on the Sparc machine. I was told that it is quite difficult to install LLVM there so I am doing what I am doing. Is there a way for me to get headers from the target Sparc machine without installing LLVM there?
