Bug ID: 95347
Summary: rs6000 mcpu=future generating stfs instead of pstfs
for pc-relative references
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: acsawdey at gcc dot gnu.org
Target Milestone: ---
Problem exists in r11-639.

./pr79354.s: Assembler messages:
./pr79354.s:31: Error: missing operand
The relevant piece of the asm output:
xscvuxdsp 0,32
pstfs 0,.LANCHOR0+16@pcrel
stfs 0,.LANCHOR0+20@pcrel
lwa 10,0(3)
pstw 10,.LANCHOR0+20@pcrel
The extended mnemonic "pstfs Fx,value" is equivalent to "pstfs Fx,value(0),1"
and is only valid for pstfs not stfs.
