|
||||
|
||||
* config/tc-m68k.h: Don't define REGISTER_PREFIX or
|
||||
OPTIONAL_REGISTER_PREFIX if either is already defined.
|
||||
|
||||
* config/tc-m68k.c (m68k_ip): Delete some code in "#if 0".
|
||||
|
||||
* configure.in: Set bfd_gas for all sparc targets. Added facility
|
||||
for keeping or rejecting configurations still under development;
|
||||
default is to assume production environment, and reject configs
|
||||
still being worked on. Mark Elf configurations (except sparc and
|
||||
i386) as developmental. Deleted cases matching some generic names
|
||||
in favor of more specific names. (E.g., when we get Alpha
|
||||
support, we'll still only support VMS for Vax.)
|
||||
|
||||
* config/tc-sparc.h (md_end): New macro.
|
||||
* config/tc-sparc.c (md_end): Function deleted.
|
||||
(BFD_RELOC_*): Delete macros that used to help keep the non-bfd
|
||||
version compiling. All sparc targets will use bfd now.
|
||||
* tc.h (md_end): Don't declare if it's defined as a macro.
|
||||
|
||||
Changes from Jeff Law and Peter Hoogenboom:
|
||||
|
||||
* read.c (next_char_of_string): Limit octal character constants to
|
||||
three digits.
|
||||
|
||||
* config/tc-hppa.h: Major cleanup. Use GNU-style comments. Warn
|
||||
against placing additional object-file dependent code here. Warn
|
||||
against contaminating all of GAS with the internals of tc-hppa.c
|
||||
through inclusion of tc-hppa.h. Delete all forward declarations
|
||||
for functions only used within tc-hppa.c, likewise for structures,
|
||||
variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
|
||||
conditional code in a few small places.
|
||||
|
||||
* config/tc-hppa.c: Major cleanup. Use GNU-style comments. Group
|
||||
structures, global variables, forward declarations together.
|
||||
Reduce (or in some cases eliminate) OBJ_ELF and OBJ_SOM
|
||||
conditional code -- try to group conditional code together
|
||||
into a few places. Make all functions and variables which
|
||||
are only used within tc-hppa.c static. PARAMize all functions.
|
||||
Add comments to functions. Delete unused functions, variables,
|
||||
#defines, etc. Delete unused members within structures. Delete
|
||||
ldil;ble hacks -- it is believed they were installed to work
|
||||
around old gas bugs. Avoid using mixed case for local
|
||||
functions, variables, and structures. Fix formatting problems
|
||||
not found by GNU-indent. Add FIXME notices for things which
|
||||
should be worked on the near future. Delete lots of old
|
||||
useless (1.36 PA-SOM) code.
|
||||
|
||||
* config/tc-hppa.c: (fix_new_hppa): Initialize the fx_r_type
|
||||
field of the fixS structure. Needed to build unwind
|
||||
descriptors correctly.
|
||||
|
||||
* write.c: (fixup_segment): Allow expressions such as
|
||||
sym1-sym2+const as long as sym2 is $global$.
|
||||
|
||||
* write.c (adjust_reloc_syms): Provide a hook so that a target
|
||||
cpu configuration can reject certain relocation reductions.
|
||||
* tc-hppa.h (tc_fix_adjustable): New macro. Only accept relocations
|
||||
which do not involve function symbols.
|
||||
|
||||
* config/tc-hppa.h: Reindent with GNU-indent. Delete references
|
||||
to OBJ_OSFROSE. Fix typos (OBJ_SOME -> OBJ_SOM). Delete unused
|
||||
STAB_FIXUP macro.
|
||||
* config/tc-hppa.c: Likewise.
|
||||
|
||||
* config/tc-hppa.c (md_apply_fix_1): Use elf_symbol_type, instead
|
||||
of elf32_symbol_type.
|
||||
(pa_export_args): Likewise.
|
||||
(elf_hppa_final_processing): Likewise.
|
||||
(pa_desc): Do not call obj_elf_desc. (Is pa_desc even needed
|
||||
anymore?)
|
||||
(hppa_tc_make_sections): Do not declare elf_get_symtab_map any
|
||||
ore.
|
||||
|
||||
* config/tc-hppa.c: (md_section_align): Align all sections to
|
||||
a multiple of the section alignment rather than always a
|
||||
multiple of 8.
|
||||
|
||||
* config/tc-hppa.c (hppa_tc_symbol): If the argument relocation
|
||||
bits are zero (eg they specify no relocations), then do not even
|
||||
bother adding their entries to thesymextn section.

|

operating on upper 32 bits of immediate constants to lower-half
|

relocs with adjusted constants.
