bss section. Set SEC_RELOC if there are any relocations, even for
a zero size section.
* write.c (write_relocs): In RELOC_EXPANSION_POSSIBLE case, base

messages and only print them when "print_errors" is true. Handle
empty string case like the HP assembler -- assume a value of
zero.

(set_at, load_register, macro): Changed calls to macro_build to
pass new argument for i, j and o cases.

way the attributes can only be changed once. Pass newly allocated
name to is_defined_subspace, not a pointer to the input line.
Fix typo in space/subspace rework.
(is_defined_subspace): Delete unused 2nd arg. All callers changed.
* config/tc-hppa.c (pa_import): If currently in the text segment
and a symbol is imported without type information, set BSF_FUNCTION

'L' is used to denote a local label.
(FAKE_LABEL_NAME): New macro. Defines the default name used for
the "fake" label.
* expr.c (make_expr_symbol): Delete DOT_LABEL_PREFIX code
and instead simply use the string defined by FAKE_LABEL_NAME.

* read.c (s_stab_generic): Likewise.
* config/tc-hppa.h (FAKE_LABEL_NAME): Define as L$0\001 so it's
known to be a local label.
* config/tc-i386.h (DOT_LABEL_PREFIX): Delete.
(LOCAL_LABEL, FAKE_LABEL_NAME): Define.
* config/tc-m68k.h (DOT_LABEL_PREFIX): Delete.

pa_segment_to_space. Reset BFD section flags as required by
the .subspace directive. Likewise for the section alignment.
Pass the current space to update_subspace and create_new_subspace.
(pa_spaces_begin): Only use space/subspace aliases if USE_ALIASES
is true. When not using aliases, create a BFD section for each
subspace encountered. When not using aliases replace the default
text, data, and bss segments with new ones.
(create_new_subspace): When not using aliases each subspace has a

9 to only keep a space in between identifier characters.
Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)

prototypes for all static functions. Moved existing minimal
debugging format support info #ifndef OBJ_ECOFF blocks.
(macro_build_lui): Eliminated sign_extend argument, because ECOFF

Patches from Eric Youngdale:
* make-gas.com: Find obstack.obj if it's not in the current
directory.
* read.c (s_ignore): Don't declare is_end_of_line. It's
redundant, and triggers a VMS gcc compiler bug.

current segment as an argument. (Ignored in all cases but VMS.)
All callers and definitions changed.

* configure.in: mips-bsd configuration was missing format spec.
Should use aout.
* Makefile.in (Makefile): Depends on configure.in.

"ifdef OBJ_VMS".
* expr.c: Add "const" modifier to hex_value.
* symbols.c: Finish conversion to S_* macros in the VMS only
parts of the program. Add "const" modifier to
md_[long,short]_jump_size. Remove declaration of const_flag
(which will be declared in obj-vms.h).

when some part of the struct is not fully defined by the compiler.
* obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
stabs directives.
* obj-vms.c (VMS_write_object_file): Define all vtable psects

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

fill_section before do_relocs_for and do_linenos_for.
(obj_coff_section): Handle optional quoted second argument giving
section characteristics.
(obj_coff_bss): Added to handle .bss.

md_convert_frag.
(fixup_segment): Explicitly check S_IS_COMMON before making 386
adjustment (already happened only for common symbols, but this is
clearer).

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.

correctly; discard information for now, since it only affects the
debugging information.
(tag_find_or_name): Don't insert tags in the symbol table.

sections starting from zero, rather than making them consecutive.
This makes subsequent reloc calculations easier, esp if the object
format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
allocate lcomm in .data rather than in .bss. It seems that some
tools can't cope with a non-zero sized bss before linkage.

as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
write.c (fixup_segment): check for signed .word overflow if

one element of a family.
* tc-m68k.c: use TARGET_CPU to choose default cpu type.
* te-generic.h: default to LOCAL_LABELS_DOLLAR and LOCAL_LABELS_FB
so that we can assemble hand-written libgcc code.
Fri Aug 21 14:38:44 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
* messages.c (as_warn): Use fputs, not fprintf, with a buffer that

Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
* tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
written with indirection on the last two operands, which can be
either data or address registers. Added a new operand type 'r'
which accepts either register type. Added '(' to notend stuff in

Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
* expr.c: If an expression is single comma, then return with
SEG_ABSENT rather than an error - since the sparc front end does
really strange things with things like fbge,a
* as.h: include bfd.h if using many sections
* expr.c: LOCAL_LABELS_FB had been changed to lower case - so
local labels didn't work.
* listing.c (list_symbol_table): don't core dump when there's no
symbol there.
* write.c, write.h: call fix_new with the right number of args on
the H8.
* config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
errors nices
Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
* app.c: MRI compatibility - allow single quote to start a string.
* as.c: fix typo recently introduced.
* as.h : Don't include aout/reloc.h - it's not right for COFF!
* expr.c: Much rewriting, to accomodate MRI syntax for
expressions. Also easier to read now.
* listing.c: Put back defuns
* read.c: modified to accept MRI syntax, put back listing pseudo
ops so that an assembler built with NO_LISTING ignores list ops
rather than pukes.
* write.c, write.h: fixs - only keep a reloc type in a fix if the target
machine is a SPARC or a 29K.
* config/obj-aout.c: added s_sect pseudo op
* config/obj-coffbfd.c: lints, set the filehdr flags right and
fill in the timestamp.
* config/obj-coffbfd.h: Since we don't include aout/reloc.h
anymore, define all the relocs which the tc-<x> bit will use so we
can translate from them to the coff types.
* config/tc-a29k.c: reloc_type isn't ane enum any more
* config/tc-m68k.c: Added NO_RELOC definition.
Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
* Makefile.in: put header files before C source for TAGS; remove
references to non-existent syscalls.h.
* read.c, write.c subsegs.c: back out the .bss changes.
* obj-aout.c: do not include stab.gnu.h if NO_LISTING.
* tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
* a.out.h: removed.
Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
* symbols.c (local_label_name): symbols now start with ^A.
* read.c, subsegs.c, write.c obj-coff.c: added handling of
`.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
generate these sections. .align: will use NOP_OPCODE or 0
for padding. This is just for being nice to the
disassembler.
* expr.c (operand): changed to generate local label "\001L0"
starting with a ^A so that it is recognized as a local label.
* as.c (perform_an_assembly_pass): zero bss_fix_root, too.
* tc-i386.c: tc-i386.c: added handling of the following opcodes:
i/o opcodes - inb, inw, outb and outw. string manipulation with
att syntax - scmp, slod, smov, ssca, ssto.
* obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
to just after .file .
In obj_crawl_symbol_chain() where it tries to put the external
symbols apart, with the condition:
(!S_IS_DEFINED(symbolP) &&
!S_IS_DEBUG(symbolP) &&
!SF_GET_STATICS(symbolP))
it was moving too many symbols out. So I switch it back to the
condition:
(S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
so that we don't use the F_RELFLG which make the linker complain
that somebody has stripped the relocation info.
Also, the AIX ld program require that the relocation table
is sorted by r_vaddr like the standard ATT assembler does.
[he also changed the sizeof(struct ...)'s into the coff
style FOOSZ macros. I'm not sure this is right, but I can't
remember why. xoxorich.]
Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)

Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
* read.c: white space and comments only.
* configure.in: use the new atof-ns32.c for ns32k.
* write.c: comment change only.
* tc-m88k.[hc]: pulled in from hack's unfinished work. These
aren't yet integrated.
* tc-i860.[hc]: blew off the dust. Something must still be done
about conflicting relocation types.
* tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
real thing.
* tc-i960.c, tc-sparc.c: white space and comments only.
* tc-a29k.h: delete duplicate macro definition.
* new file atof-ns32k.c copied from hack's last unreleased gas.
Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
* config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
rather than abort.
* nearly everything. flush ChangeLog, package as gas-1.92.1.
ChangeLog's prior to this are sketchy at best. I have logs.
They just aren't ChangeLogs.
