Fri Jan 4 12:48:22 EST 1991 Jay Fenlason (hack@ai.mit.edu)
* messages.c Moved as_perror from input-scrub.c Modified the
error messages to look better.
* output-file.c Don't call as_fatal, just call exit()
expr.c Slightly improve checking for foo-foo case in
clean_up_expression(). Detect foo: bar: ... foo-bar...
Tue Dec 4 16:29:20 EST 1990 Jay Fenlason (hack@ai.mit.edu)
* m68k.c Fixed an obscure bug involving AOFF mode with a
large constant displacement (Was forgetting to output the
extension word.)
make-gas.com Added a three line patch from Eric Youngdale that
makes it possible to submit make-gas.com to a batch queue.
Wed Nov 21 15:07:51 EST 1990 Jay Fenlason (hack@ai.mit.edu)
* vms.c (VMS_TBT_Routine_END) Add a four line patch from
Eric Youngdale.
Tue Nov 13 14:02:15 EST 1990 Jay Fenlason (hack@ai.mti.edu)
* vms-dbg.c (VMS_DBG_record()) Another one character patch from
Eric Youngdale.
Mon Oct 29 15:49:21 EST 1990 Jay Fenlason (hack@ai.mit.edu)
* read.c Replace some as_warn calls with as_bad.
Fri Oct 26 15:21:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* i386.c, i860.c, ns32k.c Add const changes.
Mon Oct 22 14:04:26 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* sparc.c Add const changes.
* make-gas.com define const= for VMS, since many older versions of
GCC don't work correctly with const under VMS.
Thu Oct 18 12:44:11 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* i860.c i860-opcode.h Added patches from rgb@mcc.com
* read.c, symbols.c, vms.c, + new_file vms-dbg-module.c
Added Eric Youngdale's <YOUNGDALE@v6550c.nrl.navy.mil> VMS debugging
patches, so debugging GCC output now works.
* hash.c (hash_grow) Remember to blank out the wall entry in the new
hash table. This is important on systems where malloc() returns
non-zero storage. . .
Tue Oct 16 10:11:35 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* output-file.c (output_file_create) if output filename is given as
'-', write to stdout.
* m68k.c Finally get the PCREL code to work right. Add relaxation of
PCREL stuff This small fix from Ken Woodland
(kenny%datacube.uucp@uunet.uu.net).
* m68k.c Added some const declarations to constants. (md_relax_table,
md_pseudo_table, etc. . .)
Thu Oct 11 11:15:10 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* Makefile, read.c, write.c Include the i860 port.
(New files i860.c i860-opcode.h i860.h)
* m68k.c Fix some addressing modes, (AOFF, AINDEX, etc) to work in
PC relative mode.
* (all over) Raeburn's const hacking. This reduces the data-space size by
declaring many tables, etc, as 'const'.
Mon Oct 22 22:48:22 1990 John Gilmore (gnu at cygint)
Make gas work if you turn on the know() checks.
* app.c: Only pass a single space through: the one after
the opcode. All other whitespace is removed, to match the
expectations of the parser in read.c.
* as.h: Remove obsolete comments. Remove JF's NDEBUG so
that know() can really work if you turn it on. Make
SEG_MAXIMUM_ORDINAL == SEG_REGISTER.
* expr.c (operand): Change BITS_PER_INT to 8*sizeof(int).
* input-scrub.c: strlen("\0") doesn't return 1...
(as_where): Add space after line number in errors, like gcc.
* m68k.c (s_bss): Fake .bss into data section 255.
We can't cope with a real "BSS section" yet, but we can at
least do the right thing less efficiently (with lots of
zeroes).
* read.c: Turn lots of as_warn()'s into as_bad()'s.
* read.h (SKIP_WHITESPACE): Replace last instance of ASSERT()
with know().
* sparc.c (s_seg): We can't put frags into the BSS segment
yet, so just fake bss seg as 255th data segment.
* vax.c: Remove \'s from continued macro *parameters*. These
must have been added after the last time someone turned on
know() checking...
* write.c (relax_segment): Refine what we know() about the
symbols referenced during relaxation.
* Makefile (OTHER_ALIGN): Remove, handled in tables now.
Flip options a bit. These options really ought to go
elsewhere.
Sun Oct 21 03:57:21 1990 John Gilmore (gnu at cygint)
Sun-3 fixes.
* expr.c, write.c: Missing semicolon after know().
* write.c (fixup_segment): Allow pc-relative accesses to undefined
external symbols. Previously this would turn off pc-rel calc
of displacement, while leaving pc-rel opcode alone, botching.
* m68k.c (m68k_ip): Allow pc-relative effective addresses
for source operands. "pea" instructions are a good example
where we can shorten from abs long to pc+16bit.
(md_convert_frag): Fix "JBSR" comments to refer to "JSR", the
actual instruction. Insert comments about bug in 68000 bcc
and dbcc long code (that doesn't get exercised much). Add
comments about long pcrel displacements for -pic. Remove
"this code has not been tested" comment.
(md_estimate_size_before_relax): Now that fixup_segment
doesn't shortcircuit pc-relative fixups for undefined symbols,
only output them if -pic; else turn them absolute, which is
slightly faster. More JBSR->JSR comments.
(md_parse_options): Parse -pic.
Fri Oct 19 14:35:20 1990 John Gilmore (gnu at cygint)
* Make sparc assembler more compatible with Sun assembler.
sparc.c: reformat pseudo-op table to match main table.
(md_assemble): Add SPECIAL_CASE_FDIV to assemble FDIV*
instructions as fdiv followed by fmovs to get around chip bug.
(s_common, s_seg): Accept "bss" section name.
(md_assemble): Handle "set" instructions with absolute
operands, that only take one instruction rather than two.
sparc-opcode.h (fdiv*): Mark instructions "S"pecial.
subsegs.c (subseg_change): Move tail pointer too.
symbols.c (colon): Allow new definitions to override .comm symbols,
as in VMS. Sun CC depends on this.
write.c (new_fix): Always take r_type argument, not just on sparc.
Chain fixP's in order, using tail pointer, so relocation
records come out in forward order like Sun as. Remove SPARC
ifdefs.
write.h: Add seg_fix_tailP, data_fix_tailP, text_fix_tailP.
* am29k.c: Use s_align_bytes rather than a local copy.
* read.c (s_align): Rather than ifdef it, make two functions,
s_align_bytes and s_align_ptwo. Individual pseudo-op tables
can call whichever one they like.
* write.c (append): Move from append.c to here.
append.c: Remove file.
* Makefile (MDSRC, mdsrc): Easy way to edit all md.c's.
Fix options. Add option for -DDEBUG for know() and assert().
Remove append.c, am29k.h. Don't build special read-sparc.o.
Remove sparc.h. "make clean" removes am29k .o's. Add
dependencies on reloc.h.
Thu Oct 18 17:56:34 1990 John Gilmore (gnu at cygint)
* Generalize sparc extensions to relocation info. Gas now
keeps relocation information internally in a different format
than how it is stored in the resulting .o. md_ri_to_bytes()
converts to external format. md_reloc_size says how large
each relocation record is in external format.
sparc.h: Remove this file. Rename to reloc.h. Rename struct
to reloc_info_generic.
reloc.h: Add relocation types for AMD 29000.
read.c, write.c: Always call fix_new with reloc-type argument.
write.c (emit_relocations): Make md_ri_to_bytes write directly
to output area rather than overwriting its argument then
bcopying it.
md.h: Declare md_reloc_size and md_ri_to_bytes.
i386.c, am29k.c, vax.c, ms32k.c, m68k.c, sparc.c: include reloc.h.
(md_reloc_size): Specify correct value.
(md_ri_to_bytes): Convert format from internal to external.
write.c (write_object_file): Call md_section_align() which
rounds section sizes up if desired.
sparc.c (md_section_align): Round to 8 byte boundary.
i386.c, am29k.c, vax.c, ns32k.c, m68k.c (md_section_align): Nop.
Mon Oct 15 22:06:11 1990 John Gilmore (gnu at cygint)
Changes in support of the AMD 29000 version of gas.
* am29k-opcode.h: Add dummy entry to end so we can examine
item N+1 without exceeding table.
* am29k.h: New include file, derived from sparc.h. Kludged
together, still needs major work to get relocation working.
* am29k.c: New file, derived from sparc.c.
Put 29k-specific ASM29K pseudo-ops into table.
Change comment_chars to ASM29K.
Change s_seg to s_use.
Change s_sparc_align to s_29k_align, default operand to 4.
(define_some_regs): Define special register names.
(md_begin): Preprocess opcode table to mash together all
the variants of single opcodes. This simplifies later handling.
Call define_some_regs to preset special reg names.
(parse_operand): Add, parses out an operand from a stmt.
(machine_ip): Simplify, since 29K is simpler asm language.
Handle the various keyletters in the opcode table.
Handle include files in the assembler, with a .include
pseudo-op.
* as.h (input_scrub_include_file): declare.
* as.c (perform_an_assembly_pass): Avoid buffer hacking.
Start us off in text segment.
* read.c (read_a_source_file): Take a name as argument,
internalize all buffer handling. Don't start a new text
subsegment on each entry. Actually use the start and end
pointers returned by input_scrub_next_buffer.
(s_include): Call input_scrub_include_file for .include.
* input-scrub.c: Fix comments.
(struct input_save): Add, for saving state at .include.
(input_scrub_push, input_scrub_pop): Add, push & pop state.
(input_scrub_begin): Initialize next_saved_file.
(input_scrub_end): Free buffer.
(input_scrub_include_file): Add, to include a file.
(input_scrub_close): Add, to close a file.
(input_scrub_next_buffer): Set buffer-start address for
caller. If we hit EOF and were included, pop to previous file.
* input-file.c: Remove old includes. Remove old file-descriptor
hacking code, that was commented out.
(struct saved_file): Add, for saving state at .include.
(input_file_push, input_file_pop): Add, push & pop state.
(input_file_open): Don't buffer all files in one place.
(input_file_close): Add, close input file.
* input-file.h: Declare new functions.
* app.c: (struct app_save): Add, for saving state at .include.
(app_push, app_pop): Add, push and pop state.
(do_scrub_next_char): Move its static state variables out so
they can be saved and restored.
* app.c: Allow overriding of character meanings by machine
dependent strings. Avoid wiring character constants into app.c.
(do_scrub_begin): New meanings override old ones, not "OR" them.
Only handle /* comments if / is not already in use.
(do_scrub_next_char): Reorganize mass of nested if's
into a switch for speed. Don't assume ';' is line terminator.
Reorganize switch on characters, into a switch on their (machine-
dependent) lexer table meanings.
Encapsulate knowledge of segment types in fewer places.
This allows us to add the "SEG_REGISTER" type, as well as
providing flexibility for eventual COFF/ELF support.
* struc-symbol.h (symbol_to_segment, symbol_to_segment_type,
set_symbol_segment, set_symbol_segment_keep_ext,
segment_name): Define macros to encapsulate this info.
* as.h: Remove externs for seg_name, seg_N_TYPE, N_TYPE_seg.
* symbols.c (symbol_new): Change 'type' arg to 'seg'.
* expr.c, i386.c, m68k.c, ns32k.c, read.c, symbols.c, vax.c,
write.c: Use macros.
* i386.c, m68k.c, ns32k.c, vax.c, write.c: Change 2nd arg type of
md_estimate_size_before_relax.
* expr.c, read.c: Change 'type' arg to symbol_new.
* read.c, symbols.c, vax.c, write.c: Move md.h to end of includes.
Allow expressions to evaluate to registers.
* as.h: Add SEG_REGISTER.
* struc-symbol.h: Add fake N_REGISTER type.
* subseg.c: Add types to tables.
* expr.c (operand): Symbols of SEG_REGISTER type are
immediately evaluated like those of SEG_ABSOLUTE.
(clean_up_expression): Clean up SEG_REGISTER exprs.
Allow machine descriptions to cleanly extend the set of
possible operands.
* expr.c (operand): Call md_operand before rejecting an
operand as unacceptable.
* md.h: declare.
* i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
* am29k.c (md_operand): Use this for %% and & prefix operators.
Allow machine descriptions to cleanly permit symbols to be
predefined upon first usage.
* symbols.c (symbol_find_or_make): Call md_undefined_symbol
before making an undefined symbol.
* md.h: declare.
* i386.c, ns32k.c, m68k.c, sparc.c, vax.c: Define null function.
* am29k.c (md_undefined_symbol): use this for the local and
global register names; since there are hundreds of them, it
only defines them upon their first use.
* expr.c (operand): Call symbol_find_or_make rather than
roll our own undefined symbols.
Miscellaneous changes:
* as.h (know): Make this useful if DEBUG defined.
* write.h: Support SPARC-like relocation throughout all
versions.
* read.c (read_a_source_file): Report the name of invalid
pseudo-ops. Don't double-report junk characters. Close the
input file, which gas never used to do.
(ignore_rest_of_line): Report junk chars in ascii if
printable.
(s_ignore): Ignore entire statement; used for 'listing
control' statements from ASM29K, e.g. .eject.
* read.c (s_lsym): Handle register equates too.
* read.c: Add most ASM29K pseudo-ops to the master table.
Not all are implemented yet.
* cond.c: New file, for functions implementing conditional
assembly pseudo-ops: .ifdef, .ifndef, .else, .endif, .ifseq,
.ifsne, .end. So far, they are just stubbed out.
* read.c (pobegin): Allow the machine dependent pseudo-op
table to override the generic one. Remove #ifdef SPARC
on .word, since it can now be overridden.
* expr.c (operand): Support radix-2 constants. Kill off
support for octals with digits '8' and '9'. Initial steps
toward more general support for local-labels.
* symbols.h (symbol_table_lookup): Remove macro, change all
occurrences (in read.c, expr.c, symbols.c) to symbol_find.
* read.h (is_end_of_line): Define for external use.
* i386.c (alloca): Use builtin_alloca or include or extern.
* Makefile: Add ALL and all: entries. Add asm29k entries.
Add cond.c and cond.o. Remove special handling for messages.o.
Add lint entry.

Tue Sep 25 15:50:36 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* sparc.c (md_number_to_imm) Fix so that RELOC_32 locations contain
zero, so that it will work with some sparc loaders which don't assume
that the locations in question do. A xix line patch from Michael Bloom
(usc!srhqla!quad1!psivax!ttidca!mb@zaphod.mps.ohio-state.edu)
Mon Sep 24 11:43:15 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* as.c #include <sys/types.h> if _POSIX_SOURCE defined. This because
<signal.h> uses pid_t that's defined in it.
* m68k.c reverse the sense of -l option, and allow :w and :l to
override the default size of AOFF indexes.
Also, allow -l to shorten branches to unknown labels from LONG to WORD.
Thu Sep 13 17:05:09 EDT 1990 Jay Fenlason (hack@ai.mit.edu)

Tue Sep 4 11:40:21 EDT 1990 Jay Fenlason
* read.c (pseudo_set) Compain if we're setting the symbol to the
difference of two symbols which are in different frags. (We can't
find out how far apart they are.)
Wed Aug 15 12:18:58 EDT 1990 Jay Fenlason
* m68k.c (m68k_ip_op) Dyke out the code that deals with parsing
:[wl] at the end of expressions since it is handled in get_num()
and this was putting the result in the wrong place anyway.
Corrected a couple of other references to ->isiz instead of con?->e_siz
Mon Aug 13 15:53:46 EDT 1990 Jay Fenlason
* read.c Handle .align specially on the sparc, or any other machine
where OTHER_ALIGN is defined. Added option and comments about it
to Makefile.

aim.
(fixup_segment) On ns32k, don't subtract size from
add_number on pcrel external symbols.
* ns32k.c (md_relax_table) Use correct max displacements.
This is a six-line patch from ian@sibyl.eleceng.ua.oz.au
* ns32k.c (md_atof, convert_iif) Emit floating point numbers in
the correct byte order. A seven line patch from
ian@sibyl.eleceng.ua.oz.au

anywhere.
Fri Jun 15 15:53:30 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
* vax.c (md_parse_option) make the code agree with the documentation

to "unknown opcode".
Wed May 16 15:33:14 EDT 1990 hack@wookumz
* i386.c (i386_operand) Print error msg if given an operand like
4(mumble) which we can't parse.
* m68k.c (md_assemble) Add '3' to the list of operand-places that

Thu Apr 26 15:17:31 EDT 1990 hack@wookumz
* atof-ieee.c Change value of NaNs to 0x7fff ffff (float) and
0x7fff ffff ffff ffff (double) If you want some other value for
NaN, use .long and spell it out yourself.
atof-generic.c (atof_generic) Cleaned up code that detects NaN
and Inf.
vax.c (md_assemble) print a useful error message if expression()
returns SEG_PASS1 or SEG_DIFFERENCE and we can't deal with those.
Thu Apr 19 10:30:47 EDT 1990 hack@wookumz
* input-scrub.c (AFTER_STRING) Make AFTER_STRING contain a null

Wed Aug 2 12:55:?? 1989 Jay Fenlason (hack at apple-gunkies.ai.mit.edu)
* sparc.c (comment_chars[]): Removed '|' because it was causing
problems. Probably not the best fix, since I suspect other
assemblers (68020) may get | in .stabs also, and the 68020 needs
the '|' comment character.

There was a bug when using %ebp as a base register with no
displacement
Instructions like andb $0xffffff, %al used to put out too many
immediate bytes
The splitting jump instructions across frags could happen when
obstack_room()==6 too.
