$extend. Based on code from Eric Freudenthal
<freudenthal@nyu.edu>.
* config/tc-a29k.h (LEX_DOLLAR): Define.
* read.c (LEX_DOLLAR): Define if not defined.
(lex_type): Use LEX_DOLLAR.
putting value into object file into separate function. Separate
out MRI and WANT_BITFIELDS cases into separate functions.
(emit_expr): New function to write data into object file.
Conditionalize on TC_CONS_FIX_NEW and TC_CONS_RELOC rather than on
processor types.
(parse_bitfield_cons): New function to parse bitfield expressions
as used by i960 assemblers. Only compiled if
BITFIELD_CONS_EXPRESSIONS is defined.
(parse_mri_cons): New function to parse MRI style strings. Only
compiled if MRI is defined.
(parse_repeat_cons): New function to parse repeat counts. Only
compiled if REPEAT_CONS_EXPRESSIONS is defined.
* read.h (emit_expr): Added declaration of new function.
* config/tc-a29k.h (TC_CONS_RELOC): Define to be RELOC_32.
* config/tc-h8300.h (TC_CONS_RELOC): Define to be R_RELWORD.
* config/tc-hppa.c (parse_cons_expression_hppa): New function to
parse a HPPA expression, rather than special case in cons
function.
(cons_fix_new_hppa): New function to emit an HPPA fixup, rather
than special case in emit_expr function.
* config/tc-hppa.h (TC_PARSE_CONS_EXPRESSION, TC_CONS_FIX_NEW):
Define to use new functions from tc-hppa.c.
* config/tc-i960.h (BITFIELD_CONS_EXPRESSIONS): Define.
(WANT_BITFIELDS): Removed; now obsolete.
* config/tc-mips.h (REPEAT_CONS_EXPRESSIONS): Define.
* config/tc-ns32k.c (cons_fix_new_ns32k): New function to emit an
NS32K fixup, rather than special case in emit_expr function.
* config/tc-ns32k.h (TC_CONS_FIX_NEW): Define to be
cons_fix_new_ns32k. Also use PARAMS rather than checking
__STDC__.
* config/tc-sparc.h (TC_CONS_RELOC): Define to RELOC_32.
* write.c (relax_and_size_seg, adjust_reloc_syms, write_contents):
Don't core dump if gas has no information about a section.
* listing.c: Call xmalloc, not malloc; don't declare malloc.
* Changes to support SCO 3.2v4:
* read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
SEG_BSS, fill with NOP_OPCODE.
* config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
* 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.
(obj_coff_val): gcc can generate values which we don't handle
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.
(write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
already defined. Fill subsegments with NOP_OPCODE, not 0. Don't
set segment address if ZERO_BASED_SEGMENTS.
(obj_coff_section): Accept and ignore a trailing quoted string, as
used in AT&T i386 syntax.
(fixup_segment): Take segment as argument. On the i386, adjust PC
relative addends by the segment vaddr.
* tc-i386.h: Define SUB_SEGMENT_ALIGN.
* tc-a29k.h: Define ZERO_BASED_SEGMENTS.
* tc-i386.c: (i386_operand): If I386COFF, accept any segment type.
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.
* 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.
