Bug ID: 62177
Summary: mips-rtems ICE at lra_assigns.c:1335 compiling
strtod.c in newlib
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: joel at gcc dot gnu.org
Host: x86_64-unknown-linux-gnu
Target: mips-rtems4.11

Preprocessed newlib strtod.c source to reproduce issue
Fails at -O2. Builds at -O1.
Works: /users/joel/test-gcc/b-mips-rtems4.11-gcc/./gcc/xgcc
-B/users/joel/test-gcc/b-mips-rtems4.11-gcc/./gcc/ -fno-builtin -mips3 -g
-O2 -c mips_bug.c
Adding -EL results in a failure.
