Remove assert on exec_bfd in cris_delayed_get_disassembler
cris_delayed_get_disassembler has an assert that exec_bfd can't be
NULL, but this assert can be triggered like this,
(gdb) set architecture cris
The target architecture is assumed to be cris
(gdb) disassemble 0x0,+4
Dump of assembler code from 0x0 to 0x4:
0x00000000:
../../binutils-gdb/gdb/cris-tdep.c:3798: internal-error: int cris_delayed_get_disassembler(bfd_vma, disassemble_info*): Assertion `exec_bfd != NULL' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
however, cris_get_disassembler does have code to handle the case that
bfd is NULL,
/* If there's no bfd in sight, we return what is valid as input in all
contexts if fed back to the assembler: disassembly *with* register
prefix. Unfortunately this will be totally wrong for v32. */
if (abfd == NULL)
return print_insn_cris_with_register_prefix;
This patch is to remove this assert.
