Hi,
I need to extend bfd backend to support TI C55x COFF files. I have
copied the *c54x* and renamed them to *c55x*. In doing so I can run
objdump on a c55x file format but the section data has the wrong
endianess. I haven't been able to affect the section data format.
The cpu-tic55x.c looks like:
const bfd_arch_info_type bfd_tic55x_arch =
{
16, /* 16 bits in a word */
16, /* 16 bits in an address (except '548)
*/
8, /* 16 bits in a byte */
bfd_arch_tic55x,
0, /* only 1 machine */
"tic55x",
"tms320c55x",
1,
true, /* the one and only */
bfd_default_compatible,
bfd_default_scan,
0,
};
and the bfd_target looks like:
const bfd_target tic55x_coff2_vec =
{
"coff2-c55x", /* name */
bfd_target_coff_flavour,
BFD_ENDIAN_BIG, /* data byte order is little */
BFD_ENDIAN_LITTLE, /* header byte order is little (DOS
tools) */
(HAS_RELOC | EXEC_P | /* object flags */
HAS_LINENO | HAS_DEBUG |
HAS_SYMS | HAS_LOCALS | WP_TEXT ),
(SEC_HAS_CONTENTS | SEC_ALLOC | SEC_LOAD | SEC_RELOC), /* section
flags */
'_', /* leading symbol underscore */
'/', /* ar_pad_char */
15, /* ar_max_namelen */
bfd_getb64, bfd_getb_signed_64, bfd_putb64,
bfd_getb32, bfd_getb_signed_32, bfd_putb32,
bfd_getb16, bfd_getb_signed_16, bfd_putb16, /* data */
bfd_getl64, bfd_getl_signed_64, bfd_putl64,
bfd_getl32, bfd_getl_signed_32, bfd_putl32,
bfd_getl16, bfd_getl_signed_16, bfd_putl16, /* hdrs */
{_bfd_dummy_target, coff_object_p, /* bfd_check_format */
bfd_generic_archive_p, _bfd_dummy_target},
{bfd_false, coff_mkobject, _bfd_generic_mkarchive, /*
bfd_set_format */
bfd_false},
{bfd_false, coff_write_object_contents, /* bfd_write_contents */
