Hi All,

I'm programming some assembler functions (with arm-elf-as)
and I want to call it from C (arm-elf-gcc). 

My assembly functions follows the ATPCS (ARM Thumb Procedure 
Call Standard), but I don't sure if that is the best choice.

1. Should I use ATPCS or APCS (ARM Procedure Call Standard) ?.

2. Which is more efficient (from code size/speed point of view) ?.

3. Can I use APCS with Thumb code ?.

4. Which calling convention use by default arm-elf-gcc ?. 
   Should I use -matpcs option for ATPCS ?.

5. Inline assembly is independent of calling conventions ?.

Thanks in advance.

Regards,
Boris Estudiez.-
