------- Additional Comments From corsepiu at gcc dot gnu dot org 2004-12-14 13:58 ------- PR18542 and this PR are not identical:
Proof: * Compiling the example from comment #3 # m68k-rtems4.7-gcc -m68020 -O2 -o tmp.o -c pr18549.c pr18549.c: In function `foo': pr18549.c:31: internal compiler error: output_operand: invalid expression as operand # m68k-rtems4.7-gcc -m68000 -O2 -o tmp.o -c pr18549.c [No ICE] * Compling the example from PR18542: # m68k-rtems4.7-gcc -m68000 -O2 -o tmp.o -c cpuboot.c cpuboot.c: In function `boot_phase_1': cpuboot.c:8: internal compiler error: output_operand: invalid expression as operand # m68k-rtems4.7-gcc -m68020 -O2 -o tmp.o -c cpuboot.c cpuboot.c: In function `boot_phase_1': cpuboot.c:8: internal compiler error: output_operand: invalid expression as operand => The ICE from the example in PR15492 is independent of -m68020 Furthermore, no ICE occurs for the example from comment #3 with avr-*: # avr-rtems4.7-gcc -O2 -o tmp.o -c pr18549.c -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=18592
