them to zero.
* config/tc-*.h, config/te-*.h: If defining them, define them to be 1 instead
of empty.
* expr.c (integer_constant, operand): Test them at run time instead of compile
time.
* read.c (read_a_source_file): Ditto.
* symbols.c (colon): Ditto.
(dollar_*, define_dollar_label, fb_*): Define unconditionally.
* symbols.h (dollar_*, define_dollar_label, fb_*): Declare unconditionally.

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.
* read.c (s_space): Rewrite to handle general expressions. Generate rs_space
frags for non-constant values.
* write.c (cvt_frag_to_fill): Treat rs_align_code and rs_space like rs_align
and rs_org. Verify that fr_offset is non-negative, and force frag type to
rs_fill only after assertion checks.
(relax_segment): Treat rs_align_code like rs_align. Treat rs_space like rs_org
in the first switch; in the second, force the operand to a constant, and use it
for the growth size.
* configure.in: Put AC_DEFINE(sparcv9) on its own line, so that the shell
variable settings associated with it are permanent. For CPUs requiring
bfd_gas=yes, select it based on CPU only, not individual target names. Handle
m68k-hp-hpux*, not just -hpux.
* config/tc-z8k.c (tc_coff_symbol_emit_hook): Add dummy argument to match
prototype in obj-coff.h.
* configure.in: Skip tests for defining WANT_FOPEN_BIN and IBM_COMPILER_SUX.

* config/go32.cfg, config/vms-conf.h: Updated.
* config/tc-m68k.c (md_apply_fix_2, md_convert_frag_1): Always use
IBM_COMPILER_SUX version of code, with comments indicating why.
* listing.c (file_info): Use text mode when opening file for read. Use "r"
directly, no macro.
* input-file.c (input_file_open): Don't use FOPEN_RT, just use "r".
* read.c (s_include): Ditto.
* output-file.c (output_file_create): Try both "wb" and "w", don't bother with
FOPEN_* macros.
* as.h: Don't include fopen-*.h.
* config/alpha-opcode.h: Make "ret" with no operands equivalent to "ret
zero,(ra)", to match OSF1 and to be consistent with both one-operand forms.

placeholder, don't mark it as used in a relocation entry, here.
* Makefile.in (comparison): Compare using makefile code from gcc, stripped down
to discard subdir stuff and adapted to give a non-zero exit status if either
file differs.
* symbols.c (copy_symbol_attributes): New function. Copies BFD symbol flags
and calls OBJ_COPY_SYMBOL_ATTRIBUTES.
(resolve_symbol_value, case O_symbol): Call it, if X_add_number is zero. Don't

zero.

going through md_number_to_chars. This permits handling symbolic
arguments when the size is larger than sizeof (valueT), if

Wrote non-BFD_ASSEMBLER subseg_new. Now subseg_new always takes a
section name, and subseg_set always takes a segT. Changed all
callers as appropriate.
* config/obj-coffbfd.c (change_to_section): Renamed to
obj_coff_add_segment. Corrected. Made callers use subseg_new.
* config/obj-coffbfd.h (obj_segment_name, obj_add_segment):

whitespace/comment changes.
deleted some "#ifdef DONTDEF" sections relating to GDB symtabs.
* app.c, config/tc-*.c: Don't include read.h, since it is already
included by as.h.
* These are based on patches from Minh Tran-le
<mtranle@paris.intellicorp.com>.
* configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
obj_format coffbfd and gas_target i386coff for target.
(i[34]86-*-isc*): New host (uses sysv).
* config/i386aix.mt: Removed (no longer used).
* config/mh-i386aix (RANLIB): Use true rather than /bin/true.

local_bss_counter. Pass correct data and bss size to
VMS_write_object_file.

argument, rather than using local_bss_counter.
* config/tc-m88k.c (s_bss): Don't use local_bss_counter.

(do_relocs_for): Base section address on s_paddr rather than
computing it. Adjust a29k R_IHIHALF special case to account for
section paddr (used to require paddr to be zero). If there are no
reclos, set s_relptr to 0. Set relocation size in object_headers.
(fill_section): Always set s_vaddr here, removing
ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
Set STYP_INFO for .comment.
(coff_header_append): Use object headers and H_{SET,GET}_* macros.
Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
(crawl_symbols): Handle 8 character section name correctly. Use
H_{SET,GET}_* macros.
(do_linenos_for): Set lineno size in object_headers.
(write_object_file): Use H_{SET,GET}_* macros. Don't bother to
set s_vaddr here. If string_byte_count remains 4, set it back to

section characteristics.

(obj_coff_ident): Added to handle .ident (puts string in .comment
section).
(obj_coff_lcomm): Put common symbols in .bss, not .data.
(fixup_mdeps): Change to segment. Call frag_wane after
md_convert_frag.
(fixup_segment): Explicitly check S_IS_COMMON before making 386
adjustment (already happened only for common symbols, but this is
clearer).
* config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
* config/tc-i386.c (s_bss): Don't use if I386COFF.
(md_pseudo_table): Ignore .optim and .noopt.

compatibility.
(LOCAL_LABEL): Removed definition.
(DOT_LABEL_PREFIX): Defined.
* listing.c: Call xmalloc, not malloc; don't declare malloc.
* Changes to support SCO 3.2v4:
* read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
SEG_BSS, fill with NOP_OPCODE.
* config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
* config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
using ZERO_BASED_SEGMENTS.
(fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
never set segment address for SEG_E2 (.bss) and don't write out
SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
(obj_coff_endef): Don't merge labels or symbols awaiting forward
definitions, and don't merge tags with non-tags. Check for .bf
rather than just checking whether the second character is b and
the third character is f.
(obj_coff_val): gcc can generate values which we don't handle
correctly; discard information for now, since it only affects the
debugging information.
(tag_find_or_name): Don't insert tags in the symbol table.
(yank_symbols): Don't merge labels.
(write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
set segment address if ZERO_BASED_SEGMENTS.
(obj_coff_section): Accept and ignore a trailing quoted string, as
used in AT&T i386 syntax.
(fixup_segment): Take segment as argument. On the i386, adjust PC
relative addends by the segment vaddr.
* tc-i386.h: Define SUB_SEGMENT_ALIGN.
* tc-a29k.h: Define ZERO_BASED_SEGMENTS.
* tc-i386.c: (i386_operand): If I386COFF, accept any segment type.
* Makefile.in: use gas_target instead of modifying target_cpu.
From Steve Chamberlain:
Makefile.in: Handle m68*-*-coff*.
read.c, read.h: add mult argument to s_space
* app.c (process_escape): new function to handle escapes the right
way, (do_scrub_next_char): use new function

* read.c (s_fill): make the , expressions optional like the doc
says
* config/tc-h8300.[ch]: better warnings
* expr.c(expr): allow SEG_REGISTER in expressions.
* read.c(pseudo_set): register expressions can be the source of a
set.
* subsegs.c (subseg_new): Now -R forces all changes to SEG_DATA to
goto SEG_TEXT (if a.out)
* write.c (write_object_file): If a.out don't use the old way for
-R.
* config/obj-a.out (s_sect): complain if the user tries to use a
subsegment with a value which might interfere with out -R hackery.
* config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
rather than use ugly if tree. (init_regtable): insert register
names into symbol table.
