Hi,
I have a user submitted port of RTEMS to the PowerPC (IBM 403) and it uses
some instructions (or alternate names) he added to his local gas. I am
using binutils 2.6 configured for powerpc-elf. I know of the following
based on the error messages:
/usr1/tmp/cca004pL.s: Assembler messages:
/usr1/tmp/cca004pL.s:54: Error: Unrecognized opcode: `mtsprg3'
/usr1/tmp/cca004pL.s:56: Error: Unrecognized opcode: `mtsprg2'
/usr1/tmp/cca004pL.s:131: Error: Unrecognized opcode: `mtexier'
/usr1/tmp/cca004pL.s:137: Error: Unrecognized opcode: `mttsr'
/usr1/tmp/cca004pL.s:143: Error: Unrecognized opcode: `mttsr'
I am not a PowerPC expert by any definition. (OK I do own a few PowerPC
manuals :).) What is the best thing for me to do? I see two options:
1. Merge his patches.
2. If possible, change the instruction names to standard ones.
