from Bryan Ford <baford@schirf.cs.utah.edu>:
* read.c (potable): Added balign and p2align, for aligning by bytes or powers
of two independent of what ".align" does for a given target.
* doc/as.texinfo: Document them.
* config/tc-sh.c (md_convert_frag): Instead of aborting on large displacements,
print an error message. Don't invoke the code that followed the abort call
until it's been verified.
(md_assemble): Use hashed list of insns.
Print warning if 8 byte insn appears in delay slot.
(md_operand): Handle %st(sym1-sym2).
(get_arc_exp_reloc_type): Likewise.
(md_apply_fix, case BFD_RELOC_ARC_B26): Now using implicit addends
so must store them here.
some AIX versions.
* configure: Regenerated.
* configure.in: Add m68k-*-elf.
* config/tc-m68k.c (comment_chars) [OBJ_ELF]: Include '#'.
(md_pseudo_table) [OBJ_ELF]: Ignore "swbeg".
(md_begin): Set alt_notend_table['&'], so svr4-style immediate operands are
accepted.
(md_apply_fix): Argument VALP should point to valueT.
(md_convert_frag): Argument SEC should be type segT.
(md_shortopts) [OBJ_ELF]: Accept 'Q' with an argument.
(md_parse_option): Ignore it.
(md_convert_frag_1): Add in frag address for the symbol in the displacement
calculation.
* config/tc-m68k.h (TARGET_FORMAT) [OBJ_ELF]: Use "elf32-m68k".
(TARGET_ARCH): Define.
(REGISTER_PREFIX_OPTIONAL) [OBJ_ELF]: Default to 0.
(LOCAL_LABEL, FAKE_LABEL_NAME, REGISTER_PREFIX_OPTIONAL): Handle these the same
way for OBJ_ELF as for M68KCOFF.
Do generic rs_machine_dependent relaxation only if TC_GENERIC_RELAX_TABLE is
defined. Use its value as the base of the table, so the actual declaration
can be cpu-specific (and const or not as appropriate). For other cpus where
this isn't done (the majority), delete md_relax_table altogether.
For machines with WORKING_DOT_WORD, delete md_{short,long}_jump_size.
(md_relax_table): No longer const. Add PCINDEX entries.
(m68k_ip): For AINDX with simple symbol operand, generate a PCINDEX frag if PC
is used, or do normal non-AINDX processing for address register.
(m68k_init_after_args): If cpu is 68000 or 68010, fix md_relax_table to prevent
relaxation of PCINDEX/BYTE mode to SHORT, since they don't support that mode.
(md_convert_frag_1, case PCLEA/LONG): Add 4 to offset, not 2. Add support for
new PCINDEX modes.
(md_estimate_size_before_relax): Process PCINDEX/SZ_UNDEF mode.
(md_convert_frag_1, case PCLEA/SHORT): Add 2 to offset.
(m68k_ip, case most punctuation/AOFF): If using PC, call add_frag using PCLEA.
(nopic_need_relax): New static function, split out from
md_estimate_size_before_relax.
(md_estimate_size_before_relax): Call it.
(load_address, macro): In NO_PIC branches, if nopic_need_relax returns nonzero,
don't attempt GP optimization.
comments.
(struct m68k_cpu): New type.
(archs, n_archs): New variables, with single list of name/enum mapping and
aliases.
(m68k_ip): Delete the table here.
(m68k_init_after_args): Use the new table here instead of open-coding it.
(md_parse_option, case 'm'): Ditto.
fill-column in local-variables section. Change subheadings to subsections so
they can be cross-referenced. Describe broken words, frags, frag chains,
generic relaxation, relax table, m68k relaxation, m68k addressing modes, test
suite code. Add a few words about various file formats.
(run_dump_test): Note passing or failing of each phase of this test, instead of
failure of phases or passing of complete test. Ensure test file name is in
reported message.
Always resolve testcase status before returning.
If `slurp_options' fails, return and don't do test.
(slurp_options): Fix "can't open" error message.
Return -1 to indicate error.
(init_opcode_tables): Delete cpu_type_map, call
arc_get_opcode_mach instead.
(arc_common): Delete non-ELF stuff. Require leading '.' in .data.
(md_apply_fix): Delete non-ELF stuff.
Disable special handling of limm values, treat them normally.
(get_arc_exp_reloc_type): New argument `data_p'. Callers updated.
(md_assemble): All limm operands must be output by gas, the opcode
insertion routines cannot be used (they don't do anything and we're
using implicit addends now so we need to output something).
* config/tc-arc.h (FAKE_LABEL_NAME): Define.
unsigned seemingly negative number. Don't bother shifting a zero
value.
(mips_ip): For case 'j', if there are more alternatives, and the
ISA level is at least 3, don't accept an unsigned seemingly
negative number.
