Bug ID: 59602
Summary: ARM, __attribute__((interrupt("FIQ"))) causes internal
compiler error with -O0
Product: gcc
Version: 4.8.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: Sergey.Belyashov at gmail dot com
I try to compile simple program. If I use some level of optimization more than
zero then no problem. But without optimization compiler dies:
$ arm-none-eabi-gcc -O0 -marm -march=armv4 -nostdlib -std=gnu99 -c -o bootldr.o
bootldr.c
bootldr.c: In function 'fiqHandler':
bootldr.c:5:1: error: insn does not satisfy its constraints:
}
^
(insn 13 12 14 (set (reg/f:SI 13 sp)
(plus:SI (reg/f:SI 11 fp)
(const_int 4 [0x4]))) bootldr.c:5 5 {*arm_addsi3}
(nil))
bootldr.c:5:1: internal compiler error: in note_invalid_constants, at
config/arm/arm.c:15751
$ cat bootldr.c
void fiqHandler(void) __attribute__ ((interrupt("FIQ")));
void fiqHandler(void)
{
__asm__ volatile("nop");
}
$ arm-none-eabi-gcc -v
Using built-in specs.

--- Comment #1 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Not sure why anyone would want unoptimized FIQ code (read fast interrupts), but
still a bug.
Has probably been broken since Thumb2 support was added.
