8f3956b328 More Lynx support, plus better stabs-in-coff generation. 1993-09-28 19:22:08 +00:00
Ian Lance Taylor
4f0bccc7d8 Some more gcc lint, and:
* read.c (change_to_section): Removed.  This is now done by
	subseg_new.
	(get_stab_string_offset): Rearranged somewhat.  Create the section
	using subseg_new.  Store the string index in seg_info, rather than
	in a static variable.  Force the first string to be empty.  Use
	frag_more rather than FRAG_APPEND_1_CHAR.
	(s_stab_generic): Rewrote.
	* subsegs.h (segment_info_type): Added stabu union.
	* subsegs.c (subseg_new): Initialize stab_string_size to 0.
	* config/obj-aout.c: Don't include aout/stab_gnu.h.
	(obj_aout_stab, obj_aout_desc): Removed.
	(obj_pseudo_table): Removed desc and stabX entries.
	* config/obj-bout.c: Same changes as config/obj-aout.c.
	* config/obj-bout.h (S_SET_TYPE): Define.
	(tc_bout_fix_to_chars): Declare.
	* config/obj-coff.c (obj_coff_stab): Removed.
	(obj_pseudo_table): Removed desc and stabX entries.
	* config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define.
	* config/obj-coffbfd.c (current_stab_symbol): Removed.
	* config/obj-coffbfd.h (obj_symbol_type): Removed n_strx, n_type,
	n_other, n_desc and n_value fields.
	(S_{S,G}ET_{OFFSET,OTHER,TYPE,DESC}): Removed.
	(MAKE_STAB_SYMBOL): Removed.
	* config/obj-ecoff.c (obj_ecoff_stab): Renamed to ecoff_stab.
	Changed arguments and removed parsing code.
	(obj_pseudo_table): Removed stabX entries.
	* config/obj-ecoff.h (ecoff_stab): Declare.
	(OBJ_PROCESS_STAB): Define.
	* config/obj-elf.c: Don't include aout/stab_gnu.h.
	(obj_elf_stab, obj_elf_xstab, obj_elf_desc,
	elf_stab_symbol_string, elf_stab_symbol, obj_elf_stab_generic):
	Removed.
	(obj_pseudo_table): Removed desc, stabX and xstabs entries.
	(obj_elf_version): Use subseg_new, not bfd_make_section.  Don't
	set SEC_LOAD for .note section.
	(adjust_stab_sections): Get frag pointer from seg_info, rather
	than looking through frags.
	* config/obj-elf.h (S_{S,G}ET_{OTHER,TYPE,DESC}): Removed.
	(SEPARATE_STAB_SECTIONS, INIT_STAB_SECTION, OBJ_PROCESS_STAB):
	Define.
	* config/obj-vms.c (obj_aout_stab): Removed.
	(obj_pseudo_table): Removed stabX entries.
	* config/obj-vms.h (S_SET_TYPE): Define.

604633aeca * subsegs.c: Renamed non-BFD_ASSEMBLER subseg_new to subseg_set.
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):
	Define.

Also some more gcc warning removal.

4064305ec0 Changes to support stabs-in-coff 1993-09-07 17:39:56 +00:00
Ian Lance Taylor
c978e704a9 * Preliminary support for m88k-coff.
* configure.in (m88k-*-coff*): New target.  Use coffbfd and
	m88kcoff.
	* config/m88kcoff.mt: New file.
	* read.c (lex_type): New macro LEX_AT to set lex type of '@'.
	(pseudo_set): Handle difference of symbols in different fragments
	by saving the entire expression as the value of the symbol.
	* symbols.c (resolve_symbol_value): Resolve difference
	expressions.
	* config/obj-coffbfd.c (obj_pseudo_table): If TC_M88K, accept
	"sdef" as a synonym for "def".
	* config/obj-coffbfd.h: If TC_M88K, include coff/m88k.h and set
	TARGET_FORMAT.
	(S_IS_LOCAL): Any symbol which includes \001 in the name is local.
	* config/tc-m88k.c, config/tc-m88k.h: Numerous changes to bring
	m88k port up to date, and to add COFF support.

5868b1fe68 * Removed sy_forward and replaced it with an undefined expression
as the value of a symbol.
	* struc-symbol.h (struct symbol): Removed sy_forward field.  Added
	sy_resolved and sy_resolving single bit fields.
	* symbols.c (symbol_new): Don't initialize sy_forward field.
	(resolve_symbol_value): New function to adjust symbol value by
	fragment address, using recursion to resolve forward symbols.
	* symbols.h: Added prototype for new function.
	* read.c (pseudo_set): Set symbolP->sy_value to an undefined
	expression rather than setting symbolP->sy_forward.
	* write.c (write_object_file): Use resolve_symbol_value on
	symbols, keeping the common case (the old behaviour) inline.
	* config/obj-aout.c (obj_aout_frob_symbol): Removed sy_forward
	handling (subsumed by write.c change).
	* config/obj-coff.c, config/obj-coffbfd.c (obj_coff_val): Set
	sy_value rather than sy_forward.

	expression segment rather than sy_forward.
	(yank_symbols): Use resolve_symbol_value.
	(crawl_symbols): Removed extra pass over symbols.
	* config/obj-aout.c, config/obj-bout.c, config/obj-coff.c,
	config/obj-vms.c (obj_crawl_symbol_chain): Removed extra pass over
	symbols which handled sy_forward; use resolve_symbol_value
	instead.
	* config/obj-coff.h, config/obj-coffbfd.h (obj_frob_forward_symbol):
	Define.
	* config/obj-elf.c (obj_elf_stab_generic): Check expression
	segment rather than sy_forward.
	* config/obj-vms.c (VMS_Check_For_Main): Don't initialize
	sy_forward; do initialize sy_resolved and sy_resolving.
	* config/tc-hppa.h (STAB_FIXUP): Use sy_value, not sy_forward.

85051959f4 * Changes to keep a full expression as the value of a symbol, not
just a longword:
	* struc-symbol.h: New field sy_value.
	* as.h: Include expr.h before struc-symbol.h.
	* expr.h: Use struct symbol rather than symbolS.
	* symbols.c (S_GET_VALUE, S_SET_VALUE): Rewrote to retrieve value
	of sy_value field; compile unconditionally, not just if
	BFD_ASSEMBLER.
	* symbols.h: Compile S_{SG}ET_VALUE prototypes unconditionally.
	* write.c (write_object_file): Set BFD symbol value to gas symbol
	value.
	* config/obj-aout.h, config/obj-bout.h, config/obj-coff.h,
	config/obj-coffbfd.h, config/obj-generic.h, config/obj-vms.h
	(S_GET_VALUE, S_SET_VALUE): Removed macro definitions.
	* config/obj-ieee.c (S_GET_VALUE, S_SET_VALUE): Removed.
	* config/obj-coff.h, obj-coffbfd.h: Rewrote several macros to use
	S_GET_VALUE rather than ost_entry.n_value.
	* config/obj-aout.c (obj_symbol_to_chars), config/obj-bout.c
	(obj_symbol_to_chars), config/obj-coff.c (obj_symbol_to_chars),
	config/obj-coffbfd.c (symbol_to_chars): Get value to write out
	using S_GET_VALUE--don't assume it is already set.
	* config/obj-ieee.c (do_symbols): Set BFD symbol value to gas
	symbol value.
	* config/obj-vms.c (various): Don't assign directly to
	S_GET_VALUE; use S_SET_VALUE instead.

wasn't being stored into scnhdr.
	* config/obj-coffbfd.h: Add prototype of s_get_segment.

355afbcd8b Ran "indent", for GNU coding style; some code & comments still need fixup.
Removed some unneeded files.

obj-coff.c (obj_coff_endef): Use as_warn, not fprintf.
tc-m68k.c (md_assemble): 68000+68881 is okay -- could be emulating.

* tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
	 Motorola and MIT syntax; gas can now assemble either type of
	 file.
	tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.
	From Steve Chamberlain:
	m68kcoff.mt: for m68k COFF.
	obj-coffbfd.c: (fixup_mdeps) added
	 (size_section) removed bad sanity check
	 (fill_section) added rs_machine_dependent case
	 (write_object_file) call fixup_mdeps
	 (fixup_segment) set fx_subsy to 0.
	obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
	 handle m68k.
	tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
	 pseudo ops.

c593cf412b * 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.

Now compiles for sparc aout, 68k aout (MRI and MIT syntax),
29k coff.

So far works as replacement for sparc and 68k /bin/as.

410e67eb21 * config/obj-coffbfd.c: lint, don't fixup relocs if H8300, use
tc_reloc_mangle to prepare relocation if one available
