* config/tc-alpha.c, config/tc-alpha.h, config/alpha-opcode.h: New
files, based on port of gas-1.38 contributed by CMU, using a.out
variant. Updated for gas-2.x and ECOFF. Floating-point constants
are still broken, bootstrap testing incomplete.
* literal.c: Comment changes.
* listing.c (listing_source_file): Check for null listing_tail
before indirecting through it.
* expr.h (struct expressionS): Added struct tag.
* as.h: If __GNUC__ and inline are both undefined, define inline
away.
* write.c (cvt_frag_to_fill): Don't assume that fr_var for
rs_align or rs_org frags will be 1.
(relax_segment): For rs_align, if fr_var is not 1, complain if
required padding is not a multiple of the size of the pad pattern.
(fixup_segment): Leave gp-relative relocations alone. For pcrel
relocations referring to the same segment, clear fx_pcrel when
clearing fx_addsy.
* as.h: Adjust comments on rs_align.
* atof-generic.c: Some reformatting.
(atof_generic): Be careful when mixing signed/unsigned values of
different sizes.
* write.c, config/obj-{aout,bout,coff*}.c, config/tc-sparc.c:
Query the fx_done field instead of fx_addsy to see if the fixup
still needs to be applied. Set fx_done and clear fx_addsy both,
for now. If TC_HANDLES_FX_DONE isn't defined, assume md_apply_fix
will only clear fx_addsy, and set fx_done accordingly after
returning.
* config/tc-sparc.h (TC_HANDLES_FX_DONE): Define.
* config/tc-sparc.c (md_apply_fix): Set fx_done for non-pcrel fix
with no fx_addsy.
* symbols.c (dot_text_symbol, dot_data_symbol, dot_bss_symbol):
Deleted.
(symbol_begin): Moved to end of file, so function inlining can
work better.
(fb_label_count, fb_label_max): Default C static initializers are
sufficient.
* symbols.h (dot_text_symbol, dot_data_symbol, dot_bss_symbol):
Declarations deleted.
* config/obj-coff.c (dot_text_symbol, dot_data_symbol,
dot_bss_symbol): Defined here, static.
* config/obj-aout.c [BFD_ASSEMBLER]: Undef NO_RELOC before
including aout/aout64.h.
* write.c (write_object_file): If EMIT_SECTION_SYMBOLS is false,
don't write out a section symbol even if it's used in a
relocation; assume relocations will handle section numbers
somehow. Rename "punt_it" label to "punt_it_if_unused" to reflect
it's true use.
(EMIT_SECTION_SYMBOLS): Default to 1.
(adjust_reloc_syms): Don't create a new symbol for an absolute
reference; just use the absolute section symbol.
(write_relocs): Make printout of reloc values dependent on flag
DEBUG3, not DEBUG2.
* config/obj-aout.h (EMIT_SECTION_SYMBOLS): Define as 0.
* config/obj-ecoff.h (EMIT_SECTION_SYMBOLS): Ditto.

* read.c (lex_type): No longer make '{' a valid character for
