6bc14195fb Rework space/subspace handling in PA code to fully support
SOM spaces/subspaces.
	* tc-hppa.c (USE_ALIASES): New object-format dependent define
	to control the use of space/subspace name aliases.
	(update_subspace): Accept space chain entry for containing space
	as a new parameter.  All callers changed.
	(pa_get_label): Use current_space rather than pa_segment_to_space.
	(pa_define_label): Likewise.
	(pa_undefine_label): Likewise.
	(md_begin): Change into the (possibly modified) text_section.
	(pa_parse_space_stmt): Create a new segment/space if create_flag
	is true, and the space name is not one of the two predefined spaces.
	(pa_subspace): Use current_space rather than a lookup via
	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
	section/segment and subsegments are not needed, so set the subsegment
	to zero.

548ea75baa * config/tc-hppa.c (pa_parse_space_stmt): If needed, call

        BFD backend.

        obj_set_subsection_attributes.

        obj_set_subsection_attributes.

12696e9cb5 * config/ho-hppabsd.h: Delete IO* macros, they are defined in

53c0b9e754 Back out of last change. Instead:
* config/tc-hppa.c (md_begin): Disable "-R" option to fold
        text and data segments.  Warn user "-R" is unsupported on the
        PA.
1993-10-29 21:08:19 +00:00
Jeff Law
37ed805e49 * as.c (main): Disable "-R" option if NO_FOLD_DATA_AND_TEXT
is defined.
        * config/tc-hppa.h (NO_FOLD_DATA_AND_TEXT): Define.  Folding
        of text and data segments fails miserably on the PA.

48ac0c90e9 * config/tc-hppa.c (pa_space): Do not report an error for a .space
directive which does not define a "well-known" space and does
	not include a space number as an argument.

	"defined", "loadable", "code_only" and "space_index" fields.
	(pa_def_spaces): Correct initialization of the "spnum", "defined",

	* config/tc-hppa.c (hppa_fix_struct): Delete unnecessary fix_fixP and

	of OBJ_XXX conditionals.
	(MAX_RELOC_EXPANSION): Likewise.

	* config/tc-hppa.c (log2): Renamed from is_power_of_2.  Fix all
	callers. Now returns log2 (N) for positive N which are an exact
	power of two or -1 for an error.

	* config/tc-hppa.c (pa_callinfo): Range check values provided for
	ENTRY_GR, ENTRY_FR and ENTRY_SR.  Properly adjust vaues before
	inserting them into the unwind table.

	* config/tc-hppa.c (NEEDS_FIXUP): Delete definition and all references.
	(hppa_gen_reloc_type): New object format dependent macro.
	(pa_ip): Delete tons of code which was either OBJ_SOM or OBJ_ELF

	(pa_build_unwind_subspace, process_exit, pa_exit): Likewise.

	* write.c (fixup_segment): Fix indention and open/close brace
	problem.

	From Pete Hoogenboom:

6121fb06ad * config/tc-a29k.c (md_begin): When opcodes are mashed together in
the table, require that the one without bit 0x1000000 set come
	first.  Require further that it be case 'b' or 'P'.  The a29k
	opcode table already meets these constraints.
	(machine_ip): When handling case 'i' or 'A', make sure that the
	appropriate opcode really exists by looking at the next entry in
	the opcode table.

* config/tc-i386.c: (md_begin): Do not zero static arrays.  Don't
	call strchr for each character to see if it is a special char,
	instead add a second loop over special_chars.  Set alignment
	of text, data and bss sections to 4.
	(pi, te, pt, pe, ps): Add declarations so that DEBUG386 can be
	used again.
	(reloc): Don't return 8 and 16 bit non-PC relative relocations on
	ELF, since the ELF object format does not have these type of
	relocations.  Change the abort into as as_bad and return
	BFD_RELOC_NONE to silence compiler warnings.
	(md_assemble): Keep track of the instruction size.  Allow white
	space between the $ and the constant for compatibility with older
	gases and other assemblers.
	(i386_operand): Skip spaces between $ and expression.
	(tc_gen_reloc): Don't allow anything but 32 bit relocations on
	ELF.  Convert abort into an as_bad and assert into as_fatal.
