Bug ID: 110630
Summary: Missed optimization: bb-slp-pr95839.c not vectorised
with V2SF targets
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: macro at orcam dot me.uk
CC: rguenth at gcc dot gnu.org
Blocks: 53947
Target Milestone: ---
With targets that only support the V2SF vector mode such as:
mips-linux-gnu-gcc -march=mips64 -mabi=64 -mpaired-single
scalar code is produced for V4SF data with bb-slp-pr95839.c while a
pair of V2SF operations would be more efficient.
