Raw Blame History

Mon Mar 29 12:56:56 1993 Ian Lance Taylor (ian@cygnus.com)
* configure.in: Set BFDDEF and BFDLIB at the top of Makefile, not
the bottom (make expands variables in dependencies when the
dependencies are read, not when they are used).
* config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
a29k .bss section; the mondfe program doesn't like it.
Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
* config/tc-mips.c: Reindented to GNU standards.
Thu Mar 25 08:59:14 1993 Ian Lance Taylor (ian@cygnus.com)
* config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
(fixup_segment): Add a29k special case; the linker is not prepared
to see a segment offset here.
* app.c (do_scrub_next_char): Added new state, 10, modifying state
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)
* Makefile.in: add dvi target; as-$(config).texinfo might live in
srcdir, might be in objdir.
* doc/Makefile.in: dvi depends on as.dvi
Mon Mar 22 23:59:13 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
* Makefile.in: add installcheck target
Mon Mar 22 10:19:00 1993 Ian Lance Taylor (ian@cygnus.com)

* Makefile.in (targ-cpu.o): Depend on config.h.
Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
* app.c (do_scrub_next_char): Added new state, 9, to avoid
dropping a space immediately following an identifier.
* expr.c, write.c: Rewrote assert expressions to not use multiple
lines; I don't think that can be done portably.
* config/tc-mips.c (macro): Use $AT if target register is zero in
load instruction, which it can be for a floating point load.
Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)
* write.c (write_contents): Compute the relocs before writing out
the section contents.
* config/obj-ecoff.h, config/obj-ecoff.c: Numerous changes to get
symbol table and values right.
* config/tc-mips.h (LOCAL_LABEL): If OBJ_ECOFF, any label starting
with $L is local.
* config/tc-mips.c (tc_gen_reloc): If OBJ_ECOFF, adjust the addend
by the section vma.
* config/z8k.mt (TARG_CPU_DEPENDENTS): The relevant file is
z8k-opc.h, not z8k.h.

silently.
* as.c (main): Don't catch any signals, for now.

OBJ_ECOFF as well as TARGET_BYTES_*_ENDIAN.
(struct loc, struct proc, struct file): Moved to tc-mips.c within
#ifndef OBJ_ECOFF block, since ECOFF uses different versions.
* config/tc-mips.c: Rearranged for ECOFF support. Added
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
does not support a non sign extended high 16 bits reloc. Adjusted
all callers accordingly.

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.
* write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
current segment as an argument. (Ignored in all cases but VMS.)
All callers and definitions changed.
Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com)
* listing.c: Cleaned up a bit, added prototypes, made NO_LISTING
case compile again.
Tue Mar 2 08:53:34 1993 Ken Raeburn (raeburn@cygnus.com)
* config/tc-m68k.c (isbyte): Accept all values from -255 to +255,

* config/obj-elf.c: No longer include elf/reloc.h.
(obj_elf_section): Set SEC_READONLY and SEC_CODE for text section.
(obj_elf_stab, obj_elf_desc): Deleted do-nothing and commented-out
routines.

argument to s_ignore. Put "#if 0" around unused code.
(obj_pseudo_table): Use s_ignore instead of do-nothing routines.
Call elf_xstabs for .stabs and .xstabs operators.
* config/tc-sparc.h (TARGET_FORMAT) [OBJ_ELF]: Now "elf32-sparc".
* write.c (relax_and_size_seg): Set SEC_RELOC only if fixups are
present.
* configure.in: mips-bsd configuration was missing format spec.
Should use aout.
* Makefile.in (Makefile): Depends on configure.in.
* config/tc-mips.c (append_insn): Don't check for alignment of
frag in memory; alignment of instructions in section is a separate
matter.
* config/tc-mips.c (macro_build_lui): Fix some assumptions of ANSI
C availability.
* listing.h: Always provide function declarations, not macros, so
pcc won't lose.

Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
* as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
* read.c: Finish conversion to S_* macros in the VMS only
parts of the program. Add "const" modifier to hex_value.
* as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
"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).
* write.c: Add "const" modifier to md_[long,short]_jump_size.
Fix arguments to VMS_write_object_file.
* config-gas.com: New file. Script for VMS systems to set up the
configuration to build gas for VMS, and create config.status.
* make-gas.com: Redone to work with new scheme.
* obj-vms.c: Patch to fix bug where we were not correctly parsing the
stabs directives.
* obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
will swap bytes if needed on a big endian system. Use throughout
as needed.
* obj-vms.c (obj_aout_stab): Add code to generate listing file.
* obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
types of malformed stabs. Change parsing algorithm so that we are
more certain of having all of the information that we need on hand.

resolve the data types of as many struct elements as possible
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
as symbols as well in the object file. Look for external functions
that start with "__vt.", and turn them into variables, since the
g++ compiler is incapable of doing this.

versions.
* bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
* input-scrub.c (as_where): Fix bug where as would crash if we did not

otherwise, use seg_name array.
(seg_name): Declare only if not BFD_ASSEMBLER.
(section_alignment): Declare only if not BFD_ASSEMBLER.
(big_section, reg_section, pass1_section, diff_section,
absent_section, text_section, data_section, bss_section): If
BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
mapping to segT enum values.
(tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
if these are used or defined, if BFD_ASSEMBLER.
(subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
subseg_new split into two functions.

declare with format attribute for -Wformat checking.
Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
* 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/mh-i386aix (RANLIB): Use true rather than /bin/true.
(MINUS_G): Removed.
(LDFLAGS): Added, defined as -shlib.
* config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.

local_bss_counter.
* symbols.c, symbols.h (local_bss_counter): Removed.

local_bss_counter. Pass correct data and bss size to
VMS_write_object_file.

(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.

section characteristics.
(obj_coff_bss): Added to handle .bss.
(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.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.

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.

sections starting from zero, rather than making them consecutive.
This makes subsequent reloc calculations easier, esp if the object

* Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
.word is < -32768 or > 32767. The -J flag causes the error to be

systems which don't support the broken .word hack.
as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
write.c (fixup_segment): check for signed .word overflow if
WARN_SIGNED_OVERFLOW_WORD.

* 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
tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

-subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
copyrights to '92, changed some from Cygnus to FSF.
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)
* Makefile.in, configure.in, doc: use the doc. Build it, install
it, clean it, etc.
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.
