Bug ID: 64736
Summary: [SH] ICE in dwarf2cfi.c:2318
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: olegendo at gcc dot gnu.org
Target: sh*-*-*
The problem has been discovered by another patch here:
https://gcc.gnu.org/ml/gcc-patches/2015-01/msg01962.html
It seems that something is creating RTL which is confusing dwarf2cfi.c.
It can be reproduced on trunk by setting the insn length for
define_insn_and_split "movrt_negc" to "3" (default value is "2").
I guess this is a latent bug/problem of SH reorg (maybe PR 59189) or the
dwarf2cfi.c code (maybe PR 64602).
