/* This file handles now also stubbed coff images. The stub is a small
|
|
|
|
DOS executable program before the coff image to load it in memory
|
|
|
|
and execute it. This is needed, because DOS cannot run coff files.
|
|
|
|
|
|
|
|
All the functions below are called by the corresponding functions
|
|
|
|
from coffswap.h.
|
|
|
|
The only thing what they do is to adjust the information stored in
|
|
|
|
the COFF file which are offset into the file.
|
|
|
|
This is needed, because DJGPP uses a very special way to load and run
|
|
|
|
the coff image. It loads the image in memory and assumes then, that the
|
|
|
|
image had no stub by using the filepointers as pointers in the coff
|
|
|
|
image and NOT in the file.
|
|
|
|
|
|
|
|
To be compatible with any existing executables I have fixed this
|
2002-11-07 01:12:05 +08:00
|
|
|
here and NOT in the DJGPP startup code. */

bfd target vector rationalisation
This renames the bfd targets to <cpu>_<format>_<other>_<endian>_vec.
So for example, bfd_elf32_ntradlittlemips_vec becomes
mips_elf32_ntrad_le_vec and hp300bsd_vec becomes m68k_aout_hp300bsd_vec.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.

Touches most files in bfd/, so likely will be blamed for everything..
o bfd_read and bfd_write lose an unnecessary param and become
bfd_bread and bfd_bwrite.
o bfd_*alloc now all take a bfd_size_type arg, and will error if
size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files
or bugs in linker scripts etc.
o file_ptr becomes a bfd_signed_vma. Besides matching sizes with
various other types involved in handling sections, this should make
it easier for bfd to support a 64 bit off_t on 32 bit hosts that
provide it.
o I've made the H_GET_* and H_PUT_* macros (which invoke bfd_h_{get,put}_*)
generally available. They now cast their args to bfd_vma and
bfd_byte * as appropriate, which removes a swag of casts from the
source.
o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and
aout-encap.c.
o Zillions of formatting and -Wconversion fixes.
