/* tc-a29k.h -- Assemble for the AMD 29000.
* 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.

on the 29k, this is true only if there is a symbol attatched.
on the h8, this is allways true, since no fixup is done

Sat Dec 12 15:26:34 1992 Ian Lance Taylor (ian@cygnus.com) * 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.

(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.
