Bug ID: 60949
Summary: Thumb2 LRA ICE for case pr34856.c
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: blocker
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tony.wang at arm dot com
I'm running regression test for the latest GCC trunk, and run into below ICE.
And if I disable the LRA feature with option mno-lra, the test case will pass:
./install-native/bin/arm-none-eabi-gcc -fno-diagnostics-show-caret -O3
-fomit-frame-pointer -funroll-loops -w -c -mthumb -mcpu=cortex-m3 -o
