Bug ID: 28919
Summary: powerpc e500mc Error: unrecognized opcode: `isel'
Product: binutils
Version: 2.38
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: judge.packham+glibc at gmail dot com
Target Milestone: ---
When building with -mcpu=e500mc the assembler reports produces the following
error
[ALL ] /tmp/ccafVatb.s: Assembler messages:
[ERROR] /tmp/ccafVatb.s:143: Error: unrecognized opcode: `isel'
[ERROR] /tmp/ccafVatb.s:146: Error: unrecognized opcode: `isel'
[ERROR] /tmp/ccafVatb.s:502: Error: unrecognized opcode: `isel'
[ERROR] /tmp/ccafVatb.s:3781: Error: unrecognized opcode: `isel'
According to the EREF manual isel is a valid instruction for e500mc and GCC
certainly thinks it is free to use it but gas doesn't allow it.
I'll try and narrow things down to a simple reproduction.
