Bug ID: 64366
Summary: Segmentation fault in remove_pseudos
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code, ra
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: kkojima at gcc dot gnu.org

a test case
The test case got a segfault in remove_pseudos on sh-unkonwn-elf compilers
built against trunk revision 218951 with '-O2 -m4 -ml -mlra'.
It fails also with '-O1 -mlra', though the bug looks a bit fragile.

As the bug is in LRA inheritance, it will take some time to fix it. I hope to make a patch on next week. ^ permalink raw reply [flat|nested] 4+ messages in thread
