Bug ID: 65489
Summary: [5.0 Regression] Testcase for PR 65427 ICEs at -Os on
arm-none-eabi in hoist pass
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: ktkachov at gcc dot gnu.org
Target: arm*
As reported at:
https://gcc.gnu.org/ml/gcc-patches/2015-03/msg00949.html
The testcase gcc.c-torture/execute/pr65427.c ICEs on arm at -Os with:
0x7e6f11 process_insert_insn
$TOP/gcc/gcse.c:2174
0x7e8a80 insert_insn_end_basic_block
$TOP/gcc/gcse.c:2196
0x7eab01 hoist_code
$TOP/gcc/gcse.c:3492
0x7eab01 one_code_hoisting_pass
$TOP/gcc/gcse.c:3722
0x7eab01 execute_rtl_hoist
$TOP/gcc/gcse.c:4212
0x7eab01 execute
$TOP/gcc/gcse.c:4293
The ICE is unrelated to that PR and is just exposed by the new testcase.
I can reproduce it with on arm-none-eabi with -Os -mfloat-abi=hard
-mcpu=cortex-a9 -mfpu=neon -mfloat-abi=softfp
