asan: c4x, c54x coff_canonicalize_reloc buffer overflow
Sometimes the investigation of a fuzzing bug report leads into areas
you'd rather not go. In this instance by the time I'd figured out the
real cause was a target variant that had never been properly supported
in binutils, the time needed to fix it was less than the time needed
to rip it out.
* coffcode.h (coff_set_alignment_hook): Call bfd_coff_swap_reloc_in
not coff_swap_reloc_in.
(coff_slurp_reloc_table): Likewise. Don't use RELOC type.
(ticoff0_swap_table): Use coff_swap_reloc_v0_out and
coff_swap_reloc_v0_in.
* coffswap.h (coff_swap_reloc_v0_in, coff_swap_reloc_v0_out): New.
* coff-tic54x.c (tic54x_lookup_howto): Don't abort.
* coffgen.c (coff_get_normalized_symtab): Use PTR_ADD.
* bfd-in.h (PTR_ADD, NPTR_ADD): Avoid warnings when passing an
expression.
* bfd-in2.h: Regenerate.
