Bug ID: 126123
Summary: [17 Regression] After r17-1992-ge4543a6ecc97a75,
unrecognised assembler generated
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Keywords: assemble-failure
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org
CC: avinashd at gcc dot gnu.org, jskumari at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-darwin
Target: powerpc-darwin
After the noted revision - assembly of the form:
(this in building gstore.o in libatomic)
=== powerpc64le-linux:
2 .machine power8
3 .machine altivec
...
474 lwz 3,0(8)
475 lwarx 5,0,9,0
476 cmpw 0,5,3
binutils as accepts this form,...
==== powerpc-darwin
.machine ppc7400
.text
....
mr r2,r3
lwarx r10,0,r29,0
... but Darwin's assembler does not.
======
When looking up the instruction reference I only see...
PowerPC®
lwarx RT, RA, RB
======
Is this a new instruction form that darwin's assembler does not recognise and
therefore we need to find some other solution?
