Bug ID: 117500
Summary: [avr] Don't ICE on invalid inline asm operand
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: gjl at gcc dot gnu.org
Target Milestone: ---
#include <avr/io.h>
void fn (void)
{
__asm ("r0,%i0" :: "n" (20));
}
produces an ICE, and the location pointer is at the end of the function:
$ avr-gcc-15 foo.c -mmcu=atmega8
foo.c: In function 'fn':
foo.c:6:1: error: bad address, not an I/O address:
6 | }
| ^
(const_int 20 [0x14])
during RTL pass: final
foo.c:6:1: internal compiler error: in avr_print_operand, at
config/avr/avr.cc:3997
Better issue a proper error instead of fatal_insn().
