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.

DESCRIPTION
|
|
|
|
|
These macros as used for reading and writing raw data in
|
|
|
|
|
sections; each access (except for bytes) is vectored through
|
|
|
|
|
the target format of the BFD and mangled accordingly. The
|
|
|
|
|
mangling performs any necessary endian translations and
|
|
|
|
|
removes alignment restrictions. Note that types accepted and
|
|
|
|
|
returned by these macros are identical so they can be swapped
|
|
|
|
|
around in macros---for example, @file{libaout.h} defines <<GET_WORD>>
|
|
|
|
|
to either <<bfd_get_32>> or <<bfd_get_64>>.
|
|
|
|
|
|
|
|
|
|
In the put routines, @var{val} must be a <<bfd_vma>>. If we are on a
|
|
|
|
|
system without prototypes, the caller is responsible for making
|
|
|
|
|
sure that is true, with a cast if necessary. We don't cast
|
|
|
|
|
them in the macro definitions because that would prevent <<lint>>
|
|
|
|
|
or <<gcc -Wall>> from detecting sins such as passing a pointer.
|
|
|
|
|
To detect calling these with less than a <<bfd_vma>>, use
|
|
|
|
|
<<gcc -Wconversion>> on a host with 64 bit <<bfd_vma>>'s.

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

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.
