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.

/* This is what Intel Hex files look like:
|
|
|
|
|
|
|
|
1. INTEL FORMATS
|
|
|
|
|
|
|
|
A. Intel 1
|
|
|
|
|
|
|
|
16-bit address-field format, for files 64k bytes in length or less.
|
|
|
|
|
|
|
|
DATA RECORD
|
|
|
|
Byte 1 Header = colon(:)
|
|
|
|
2..3 The number of data bytes in hex notation
|
|
|
|
4..5 High byte of the record load address
|
|
|
|
6..7 Low byte of the record load address
|
|
|
|
8..9 Record type, must be "00"
|
|
|
|
10..x Data bytes in hex notation:
|
|
|
|
x = (number of bytes - 1) * 2 + 11
|
|
|
|
x+1..x+2 Checksum in hex notation
|
|
|
|
x+3..x+4 Carriage return, line feed
|
|
|
|
|
|
|
|
END RECORD
|
|
|
|
Byte 1 Header = colon (:)
|
|
|
|
2..3 The byte count, must be "00"
|
|
|
|
4..7 Transfer-address (usually "0000")
|
|
|
|
the jump-to address, execution start address
|
|
|
|
8..9 Record type, must be "01"
|
|
|
|
10..11 Checksum, in hex notation
|
|
|
|
12..13 Carriage return, line feed
|
|
|
|
|
|
|
|
B. INTEL 2
|
|
|
|
|
|
|
|
MCS-86 format, using a 20-bit address for files larger than 64K bytes.
|
|
|
|
|
|
|
|
DATA RECORD
|
|
|
|
Byte 1 Header = colon (:)
|
|
|
|
2..3 The byte count of this record, hex notation
|
|
|
|
4..5 High byte of the record load address
|
|
|
|
6..7 Low byte of the record load address
|
|
|
|
8..9 Record type, must be "00"
|
|
|
|
10..x The data bytes in hex notation:
|
|
|
|
x = (number of data bytes - 1) * 2 + 11
|
|
|
|
x+1..x+2 Checksum in hex notation
|
|
|
|
x+3..x+4 Carriage return, line feed
|
|
|
|
|
|
|
|
EXTENDED ADDRESS RECORD
|
|
|
|
Byte 1 Header = colon(:)
|
|
|
|
2..3 The byte count, must be "02"
|
|
|
|
4..7 Load address, must be "0000"
|
|
|
|
8..9 Record type, must be "02"
|
|
|
|
10..11 High byte of the offset address
|
|
|
|
12..13 Low byte of the offset address
|

|
14..15 Checksum in hex notation
|
|
|
|
16..17 Carriage return, line feed
|
|
|
|
|
|
|
|
The checksums are the two's complement of the 8-bit sum
|
|
|
|
without carry of the byte count, offset address, and the
|
|
|
|
record type.
|
|
|
|
|

START ADDRESS RECORD
|
|
|

Byte 1 Header = colon (:)

10..13 Upper 16 bits of address of subsequent records

START LINEAR ADDRESS RECORD
|

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.
