Bug ID: 83103
Summary: Improve __mulkc3 and __divkc3 on Power9
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libgcc
Assignee: unassigned at gcc dot gnu.org
Reporter: meissner at gcc dot gnu.org
Target Milestone: ---
Right now, the __mulkc3 and __divkc3 functions that provide complex
multiply/divide support are built with the default cpu used for building
libgcc. We should use the target_clones attribute to compile these functions
with -mcpu=power9, so that these functions are faster when run on power9
hardware.
