Fri Apr 27 08:54:00 GMT 2001 

Hi!

Here is a patch for both GAS and LD that add OpenRISC support.  Also
a small change to BFD.  New files are attached in a gzipped tar archive.

/src/ld:
2001-04-27  Johan Rydberg  <jrydberg@opencores.org>

        * emulparams/elf32openrisc.sh: New file.

        * Makefile.am: Add OpenRISC target.
        * Makefile.in: Regenerated.

        * configure.tgt: Add openrisc-*-* mapping.

/src/gas:
2001-04-27  Johan Rydberg  <jrydberg@opencores.org>

        * config/tc-openrisc.c: New file.
        * config/tc-openrisc.h: Likewise.

        * Makefile.am: Add OpenRISC target.
        * Makefile.in: Regenerated.

        * configure.in (openrisc-*-*): Add target.
        * configure: Regenerated.

/src/gas/testsuite:
2001-04-27  Johan Rydberg  <jrydberg@opencores.org>

        * gas/openrisc/addi.s: New file.
        * gas/openrisc/addi.d: Likewise.
        * gas/openrisc/allinsn.exp: Likewise.
        * gas/openrisc/allinsn.s: Likewise.
        * gas/openrisc/allinsn.d: Likewise.
        * gas/openrisc/lohi.s: Likewise.
        * gas/openrisc/lohi.d: Likewise.
        * gas/openrisc/store.s: Likewise.
        * gas/openrisc/store.d: Likewise.

/src/bfd:
2001-04-27  Johan Rydberg  <jrydberg@opencores.org>

        * elf32-openrisc.c (openrisc_elf_howto_table): Do not complain about
        overflow in R_OPENRISC_LO_16_IN_INSN and R_OPENRISC_HI_16_IN_INSN.
