Bug ID: 71231
Summary: [7 Regression]: 300% runtime increase for rnflow
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: regression
Assignee: unassigned at gcc dot gnu.org
Reporter: ubizjak at gmail dot com
Target Milestone: ---
As seen in [1], there is 300% runtime increase in PH11 rnflow testcase
happening from around 19. May onward.
160516.34236259 ... 48.67
160517.34236301 ... 48.68
160518.25236346 ... -1.00
160519.34236434 ... 155.92
160520.34236491 ... 153.29
160521.34236549 ... 154.85
160522.34236559 ... 154.38
Can please someone run a regression hunt for this testcase to find the
offending commit? With such a regression, it will be fairly easy to find it
with an automated bisection.
