Bug ID: 78638
Summary: [7 regression] test cases
gcc.target/powerpc/rlwimi-0.c and rlwimi-2.c fail
starting with r243000
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: seurer at linux dot vnet.ibm.com
Target Milestone: ---
It looks like the counts of some of the assembler instructions changed with
this update and the test case needs updating.
