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

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

16 bits. The assembler has already done some of this: If the

|
|
|
|
value stored in the instruction has its 15th bit set, (counting
|
|
|
|
|
from zero) then the assembler will have added 1 to the value
|
|
|
|
|
stored in the associated HI16S reloc. So for example, these
|
|
|
|
|
relocations:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred ), r0, r1
|
|
|
|
|
movea lo( fred ), r1, r1
|
|
|
|
|
|
|
|
|
|
will store 0 in the value fields for the MOVHI and MOVEA instructions
|
|
|
|
|
and addend will be the address of fred, but for these instructions:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0x123456), r0, r1
|
|
|
|
|
movea lo( fred + 0x123456), r1, r1
|
|
|
|
|
|
|
|
|
|
the value stored in the MOVHI instruction will be 0x12 and the value
|
|
|
|
|
stored in the MOVEA instruction will be 0x3456. If however the
|
|
|
|
|
instructions were:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0x10ffff), r0, r1
|
|
|
|
|
movea lo( fred + 0x10ffff), r1, r1
|
|
|
|
|
|
|
|
|
|
then the value stored in the MOVHI instruction would be 0x11 (not
|
|
|
|
|
0x10) and the value stored in the MOVEA instruction would be 0xffff.
|
|
|
|
|
Thus (assuming for the moment that the addend is 0), at run time the
|
|
|
|
|
MOVHI instruction loads 0x110000 into r1, then the MOVEA instruction
|
|
|
|
|
adds 0xffffffff (sign extension!) producing 0x10ffff. Similarly if
|
|
|
|
|
the instructions were:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred - 1), r0, r1
|
|
|
|
|
movea lo( fred - 1), r1, r1
|
|
|
|
|
|
|
|
|
|
then 0 is stored in the MOVHI instruction and -1 is stored in the
|
|
|
|
|
MOVEA instruction.
|
|
|
|
|
|
|
|
|
|
Overflow can occur if the addition of the value stored in the
|
|
|
|
|
instruction plus the addend sets the 15th bit when before it was clear.
|
|
|
|
|
This is because the 15th bit will be sign extended into the high part,
|
|
|
|
|
thus reducing its value by one, but since the 15th bit was originally
|
|
|
|
|
clear, the assembler will not have added 1 to the previous HI16S reloc
|
|
|
|
|
to compensate for this effect. For example:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0x123456), r0, r1
|
|
|
|
|
movea lo( fred + 0x123456), r1, r1
|
|
|
|
|
|
|
|
|
|
The value stored in HI16S reloc is 0x12, the value stored in the LO16
|
|
|
|
|
reloc is 0x3456. If we assume that the address of fred is 0x00007000
|
|
|
|
|
then the relocations become:
|
|
|
|
|
|
|
|
|
|
HI16S: 0x0012 + (0x00007000 >> 16) = 0x12
|
|
|
|
|
LO16: 0x3456 + (0x00007000 & 0xffff) = 0xa456
|
|
|
|
|
|
|
|
|
|
but when the instructions are executed, the MOVEA instruction's value
|
|
|
|
|
is signed extended, so the sum becomes:
|
|
|
|
|
|
|
|
|
|
0x00120000
|
|
|

+ 0xffffa456
|
|
|
|
|
------------
|
|
|
|
|
0x0011a456 but 'fred + 0x123456' = 0x0012a456
|
|
|
|
|
|
|
|
|
|
Note that if the 15th bit was set in the value stored in the LO16
|
|
|
|
|
reloc, then we do not have to do anything:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0x10ffff), r0, r1
|
|
|
|
|
movea lo( fred + 0x10ffff), r1, r1
|
|
|
|
|
|
|
|
|
|
HI16S: 0x0011 + (0x00007000 >> 16) = 0x11
|
|
|
|
|
LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff
|
|
|
|
|
|
|
|
|
|
0x00110000
|
|
|
|
|
+ 0x00006fff
|
|
|
|
|
------------
|
|
|
|
|
0x00116fff = fred + 0x10ffff = 0x7000 + 0x10ffff
|
|
|
|
|
|
|
|
|
|
Overflow can also occur if the computation carries into the 16th bit
|
|
|
|
|
and it also results in the 15th bit having the same value as the 15th
|
|
|
|
|
bit of the original value. What happens is that the HI16S reloc
|
|
|
|
|
will have already examined the 15th bit of the original value and
|
|
|
|
|
added 1 to the high part if the bit is set. This compensates for the
|
|
|
|
|
sign extension of 15th bit of the result of the computation. But now
|
|
|
|
|
there is a carry into the 16th bit, and this has not been allowed for.
|
|
|
|
|
|
|
|
|
|
So, for example if fred is at address 0xf000:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set]
|
|
|
|
|
movea lo( fred + 0xffff), r1, r1
|
|
|
|
|
|
|
|
|
|
HI16S: 0x0001 + (0x0000f000 >> 16) = 0x0001
|
|
|
|
|
LO16: 0xffff + (0x0000f000 & 0xffff) = 0xefff (carry into bit 16 is lost)
|
|
|
|
|
|
|
|
|
|
0x00010000
|
|
|
|
|
+ 0xffffefff
|
|
|
|
|
------------
|
|
|
|
|
0x0000efff but 'fred + 0xffff' = 0x0001efff
|
|
|
|
|
|
|
|
|
|
Similarly, if the 15th bit remains clear, but overflow occurs into
|
|
|
|
|
the 16th bit then (assuming the address of fred is 0xf000):
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear]
|
|
|
|
|
movea lo( fred + 0x7000), r1, r1
|
|
|
|
|
|
|
|
|
|
HI16S: 0x0000 + (0x0000f000 >> 16) = 0x0000
|
|
|
|
|
LO16: 0x7000 + (0x0000f000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
|
|
|
|
|
|
|
|
|
|
0x00000000
|
|
|
|
|
+ 0x00006fff
|
|
|
|
|
------------
|
|
|
|
|
0x00006fff but 'fred + 0x7000' = 0x00016fff
|
2000-12-09 02:34:32 +08:00
|
|
|
|
|
1999-05-03 15:29:11 +08:00
|
|
|
|
Note - there is no need to change anything if a carry occurs, and the
|
|
|
|
|
15th bit changes its value from being set to being clear, as the HI16S
|
|
|
|
|
reloc will have already added in 1 to the high part for us:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0xffff), r0, r1 [bit 15 of the offset is set]
|
|
|
|
|
movea lo( fred + 0xffff), r1, r1
|
|
|
|
|
|
|
|
|
|
HI16S: 0x0001 + (0x00007000 >> 16)
|
|
|
|
|
LO16: 0xffff + (0x00007000 & 0xffff) = 0x6fff (carry into bit 16 is lost)
|
|
|
|
|
|
|
|
|
|
0x00010000
|
|
|
|
|
+ 0x00006fff (bit 15 not set, so the top half is zero)
|
|
|
|
|
------------
|
|
|
|
|
0x00016fff which is right (assuming that fred is at 0x7000)
|
|
|
|
|
|
|
|
|
|
but if the 15th bit goes from being clear to being set, then we must
|
|
|
|
|
once again handle overflow:
|
|
|
|
|
|
|
|
|
|
movhi hi( fred + 0x7000), r0, r1 [bit 15 of the offset is clear]
|
|
|
|
|
movea lo( fred + 0x7000), r1, r1
|
|
|
|
|
|
|
|
|
|
HI16S: 0x0000 + (0x0000ffff >> 16)
|
|
|
|
|
LO16: 0x7000 + (0x0000ffff & 0xffff) = 0x6fff (carry into bit 16)
|
|
|
|
|
|
|
|
|
|
0x00000000
|
|
|
|
|
+ 0x00006fff (bit 15 not set, so the top half is zero)
|
|
|
|
|
------------
|
2001-08-13 18:06:11 +08:00

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

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

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.
