/* read.c - read a source file -
|
* Extensive changes to permit symbols to contain any expression
type and to delay the computation of the expression until the
value is actually needed. This permits setting symbols to values
calculated based on object code size. Expressions were changed to
no longer be in a section, to stop the overloading of segment and
expression type that previously occurred.
* as.c (big_section, pass1_section, diff_section, absent_section):
Removed.
(expr_section): Added (used for dummy symbols which hold
intermediate expression values).
(perform_an_assembly_pass): Create expr_section, do not create the
sections now removed.
* as.h (segT): Removed SEG_ABSENT, SEG_PASS1, SEG_BIG, and
SEG_DIFFERENCE. Added SEG_EXPR.
(SEG_NORMAL): Corresponding changes.
* subsegs.c (seg_name, subsegs_begin): Changed accordingly.
* write.c (write_object_file): Ditto.
* config/obj-aout.c (seg_N_TYPE): Ditto.

* config/obj-vms.c (seg_N_TYPE): Ditto.
* expr.h (operatorT): Moved in from expr.c, added some values.
(expressionS): Added X_op field, removed X_seg field; renamed
X_subtract_symbol to X_op_symbol.
* expr.c: Extensive changes to assign expression types rather than
sections and to simplify the parsing.
* write.c (fix_new_internal): New static function.
(fix_new): Removed sub_symbol argument.
(fix_new_exp): New function, takes expression argument.
* write.h: Prototype changes for fix_new and fix_new_exp.
* cond.c (s_if): Changed accordingly.
* read.c (s_lsym, pseudo_set, emit_expr, parse_bitfield_cons,
parse_repeat_cons, get_segmented_expression,
get_known_segmented_expression, get_absolute_expression): Ditto.

is_complex): Ditto.
* config/tc-i386.c (pe, md_assemble, i386_operand,
md_estimate_size_before_relax, md_create_long_jump): Ditto.
* config/tc-i860.c (md_assemble, getExpression, print_insn):
Ditto.

* Extensive changes to permit symbols to contain any expression
type and to delay the computation of the expression until the
value is actually needed. This permits setting symbols to values
calculated based on object code size. Expressions were changed to
no longer be in a section, to stop the overloading of segment and
expression type that previously occurred.
* as.c (big_section, pass1_section, diff_section, absent_section):
Removed.
(expr_section): Added (used for dummy symbols which hold
intermediate expression values).
(perform_an_assembly_pass): Create expr_section, do not create the
sections now removed.
* as.h (segT): Removed SEG_ABSENT, SEG_PASS1, SEG_BIG, and
SEG_DIFFERENCE. Added SEG_EXPR.
(SEG_NORMAL): Corresponding changes.
* subsegs.c (seg_name, subsegs_begin): Changed accordingly.

(expressionS): Added X_op field, removed X_seg field; renamed
X_subtract_symbol to X_op_symbol.
* expr.c: Extensive changes to assign expression types rather than
sections and to simplify the parsing.
* write.c (fix_new_internal): New static function.
(fix_new): Removed sub_symbol argument.
(fix_new_exp): New function, takes expression argument.
* write.h: Prototype changes for fix_new and fix_new_exp.

* 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/i386aix.mt: Removed (no longer used).
* 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.
* config/te-sco386.h (LOCAL_LABEL): Don't define.
(DOT_LABEL_PREFIX): Define.
* expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
name rather than L0\001.
* read.c (s_lcomm): Make a frag in SEG_BSS rather than using
local_bss_counter.
* symbols.c, symbols.h (local_bss_counter): Removed.
* write.c (write_object_file): bss no longer uses
local_bss_counter. Pass correct data and bss size to
VMS_write_object_file.
* config/obj-vms.c (VMS_write_object_file): Accept bss size as
argument, rather than using local_bss_counter.
* config/tc-m88k.c (s_bss): Don't use local_bss_counter.
* config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
* config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
(size_section): Restored sanity check.
(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.
Set STYP_INFO for .comment.
(coff_header_append): Use object headers and H_{SET,GET}_* macros.
Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
(crawl_symbols): Handle 8 character section name correctly. Use
H_{SET,GET}_* macros.
(do_linenos_for): Set lineno size in object_headers.
(write_object_file): Use H_{SET,GET}_* macros. Don't bother to
set s_vaddr here. If string_byte_count remains 4, set it back to
0, and only write strings out if there are some. Call
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.
(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.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
* config/tc-i386.c (s_bss): Don't use if I386COFF.
(md_pseudo_table): Ignore .optim and .noopt.
(tc_coff_sizemachdep): New function.
* config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
compatibility.
(LOCAL_LABEL): Removed definition.
(DOT_LABEL_PREFIX): Defined.

(fill_section): Always set s_vaddr here, removing

You can define TC_PARSE_CONS_EXPRESSION to do whatever you like

(for example, the HPPA does this). Otherwise, you can define

BITFIELD_CONS_EXPRESSIONS to permit bitfields to be specified, or
|
|
|
|
|
REPEAT_CONS_EXPRESSIONS to permit repeat counts. If none of these

are defined, which is the normal case, then only simple expressions

type and to delay the computation of the expression until the
value is actually needed. This permits setting symbols to values
calculated based on object code size. Expressions were changed to
no longer be in a section, to stop the overloading of segment and
expression type that previously occurred.
* as.c (big_section, pass1_section, diff_section, absent_section):
Removed.
(expr_section): Added (used for dummy symbols which hold
intermediate expression values).
(perform_an_assembly_pass): Create expr_section, do not create the
sections now removed.
* as.h (segT): Removed SEG_ABSENT, SEG_PASS1, SEG_BIG, and
SEG_DIFFERENCE. Added SEG_EXPR.

sections and to simplify the parsing.
* write.c (fix_new_internal): New static function.

type and to delay the computation of the expression until the
value is actually needed. This permits setting symbols to values
calculated based on object code size. Expressions were changed to
no longer be in a section, to stop the overloading of segment and
expression type that previously occurred.
* as.c (big_section, pass1_section, diff_section, absent_section):
Removed.

intermediate expression values).
(perform_an_assembly_pass): Create expr_section, do not create the
sections now removed.

SEG_DIFFERENCE. Added SEG_EXPR.

X_subtract_symbol to X_op_symbol.
* expr.c: Extensive changes to assign expression types rather than
sections and to simplify the parsing.
* write.c (fix_new_internal): New static function.
(fix_new): Removed sub_symbol argument.
(fix_new_exp): New function, takes expression argument.
* write.h: Prototype changes for fix_new and fix_new_exp.
