relocations properly.
[ gas/ChangeLog ]
2001-10-31 Chris Demetriou <cgd@broadcom.com>
* config/tc-mips.c (HAVE_32BIT_ADDRESSES): If compiling embedded
PIC code, assume pointers the same size as GPRs.
(macro): In M_LA_AB handling for embedded PIC code, support
"la $treg,foo-bar($breg)". In load/store handling
(label ld_st) support "<op> $treg,<sym>-<local_sym>($breg)"
which is used by the compiler for switch statements.
In load/store double multi-instruction macro handling
(label ldd_std) add a comment that no special handling
is currently done for embedded PIC.
(mips_ip): In 'o' (16-bit offset) case, only accept 16
bit offsets.

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.
