Bug ID: 64434
Summary: Performance regression after operand canonicalization
(r216728).
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ysrumyan at gmail dot com
We noticed huge regression on eembc1.1 and eembc2.0 for 32-bit target at x86.
It can be reproduced on attached test-case:
before this fix number of %esp references in assembly was 2 but after r216728 -
24. Note that simple fix resolving this issue was sent for review.
