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.

/* The ns32k series is ah, unusual, when it comes to relocation.
|
2003-06-25 14:40:27 +08:00
|
|
|
There are three storage methods for relocatable objects. There
|
2001-08-14 18:01:29 +08:00
|
|
|
are displacements, immediate operands and ordinary twos complement
|
|
|
|
data. Of these, only the last fits into the standard relocation
|
|
|
|
scheme. Immediate operands are stored huffman encoded and
|
|
|
|
immediate operands are stored big endian (where as the natural byte
|
2003-11-25 02:06:40 +08:00
|
|
|
order is little endian for this architecture).
|
2001-08-14 18:01:29 +08:00
|
|
|
|
|
|
|
Note that the ns32k displacement storage method is orthogonal to
|
|
|
|
whether the relocation is pc relative or not. The "displacement"
|
|
|
|
storage scheme is used for essentially all address constants. The
|
|
|
|
displacement can be relative to zero (absolute displacement),
|
|
|
|
relative to the pc (pc relative), the stack pointer, the frame
|
|
|
|
pointer, the static base register and general purpose register etc.
|
|
|
|
|
|
|

For example:
|
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.
