Bug ID: 83815
Summary: Enhance addressing for long double on PowerPC with
-meabi=ieeelongdouble
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
Target Milestone: ---
TFmode (and TCmode) in rs6000.c is tuned for IBM extended double. With the
-mabi=ieeelongdouble option which switches long double to IEEE 128-bit, we need
to go through the various addressing functions in rs6000.c and support the
appropriate reg+reg addressing (and reg+offset in ISA 3.0).
