[LLVMdev] code generation for ARM

[James Molloy]

Hi,

 

If you want your program to work, you will have to link against a library
built for ARM. Linking against library headers built for x86 will not work,
as you are finding out.

 

You should also give llvm-gcc the -march=arm option as well as llc, because
bitcode is not target independent.

 

Cheers,

 

James

Thank you all for the inline assembly pointer. 

 

I have some macros (FD_ZERO, FD_SET) in benchmark code which comes from C
library select (synchronous I/O multiplexing) and it does contain inline
assembly. Is there a way the code containing such macros can work for ARM if
compiled through llvm?

 

Thanks

Daya

there may well be in header files you include.

This error message is complaining about inline assembler.

Ciao, Duncan.
