Bug #: 53156
Summary: [4.8 Regression]: gcc.target/cris/peep2-andu2.c
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: missed-optimization
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: hp@gcc.gnu.org
Host: x86_64-unknown-linux-gnu
Target: cris-axis-elf
This test previously passed, now it fails as follows.
The observed regression was exposed by a commit in the range (before:after)
186859:186871, most likely the reload-commit in r186861.
The fault is with the test-case: it has an assumption that a set of specific
insn sequences is generated implying that those are the only minimal sequences,
an assumption proven wrong. For one sequence change, there's a minor
regression.
