[ECOS] i960 Compile does not support the alias attribute

[ECOS] i960 Compile does not support the alias attribute

[Bill Marcotte]

Currently the i960 compiler doesn't support the alias attribute which is 
required by LIBC.  Does anybody have any good suggestions on how I might be
able to work-around this problem without modifying any sources in LibC?

Thanks in advance.

This seems most likely a COFF vs ELF problem ; as far as i know COFF does
not support aliasing like ELF does. However you might be interested in an
experimental i960-intel-elf port of gcc which is being succesfully used in
the development of an alternate i960 RP eCos port ; please tell me if you
need the patch.

Is it ELF? If so alias attributes are actually generally easy to implement
in gcc. This is generally done with ASM_OUTPUT_DEF. Implementations can be
as easy as, e.g.:

#define ASM_OUTPUT_DEF(FILE,NAME1,NAME2) \
  do { assemble_name(FILE, NAME1);       \
       fputs(" = ", FILE);               \
       assemble_name(FILE, NAME2);       \
       fputc('\n', FILE); } while
(0)                                                        

It depends on the syntax of the i960 assembler.

Ask on the gcc@gcc.gnu.org list ( see http://gcc.gnu.org/ ).
