It's redundant, and triggers a VMS gcc compiler bug. * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes current segment as an argument. (Ignored in all cases but VMS.) All callers and definitions changed. Tue Mar 2 11:56:19 1993 Ian Lance Taylor (ian@cygnus.com) * listing.c: Cleaned up a bit, added prototypes, made NO_LISTING case compile again.

Tue Sep 22 13:02:07 1992 Sean Eric Fagan (sef@cygnus.com) * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all sections starting from zero, rather than making them consecutive. This makes subsequent reloc calculations easier, esp if the object format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily) allocate lcomm in .data rather than in .bss. It seems that some tools can't cope with a non-zero sized bss before linkage. Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com) * tc-m68k.c: Replace "enum m68k_architecture" with "int" throughout.

Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com) * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any .word is < -32768 or > 32767. The -J flag causes the error to be ignored. This is to catch over-sized switches generated by gcc on systems which don't support the broken .word hack. as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD. write.c (fixup_segment): check for signed .word overflow if WARN_SIGNED_OVERFLOW_WORD. * write.c (fixup_segment): fixed missing parens in expression checking for byte or word overflow. * obj-coffbfd.h: define WARN_SIGNED_OVERFLOW_WORD. obj-coffbfd.c (fixup_segment): check for signed .word overflow if WARN_SIGNED_OVERFLOW_WORD. * obj-coffbfd.c (fixup_segment): fixed missing parens in expression checking for byte or word overflow.

From Steve Chamberlain: Makefile.in: Handle m68*-*-coff*. read.c, read.h: add mult argument to s_space * 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.

(as_bad): Likewise. Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com) * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be written with indirection on the last two operands, which can be either data or address registers. Added a new operand type 'r' which accepts either register type. Added '(' to notend stuff in tc-m68kmote.c to accept (a0):(a2) in cas2 instruction. Wed Aug 19 09:25:09 1992 Ken Raeburn (raeburn@cygnus.com) * as.h (enum _relax_state): Start off at one, not zero, to better catch uninitialized-variable errors.

Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com) * Makefile.in, configure.in: removed traces of namesubdir, -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced copyrights to '92, changed some from Cygnus to FSF. * doc/Makefile.in, doc/configure.in: removed traces of namesubdir, -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced copyrights to '92, changed some from Cygnus to FSF. Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com) * expr.c: If an expression is single comma, then return with SEG_ABSENT rather than an error - since the sparc front end does really strange things with things like fbge,a * as.h: include bfd.h if using many sections * expr.c: LOCAL_LABELS_FB had been changed to lower case - so local labels didn't work. * listing.c (list_symbol_table): don't core dump when there's no symbol there. * write.c, write.h: call fix_new with the right number of args on the H8. * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make errors nices Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com) * 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. Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com) * Makefile.in: put header files before C source for TAGS; remove references to non-existent syscalls.h. * read.c, write.c subsegs.c: back out the .bss changes. * obj-aout.c: do not include stab.gnu.h if NO_LISTING. * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place. * a.out.h: removed. Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM) * symbols.c (local_label_name): symbols now start with ^A. * read.c, subsegs.c, write.c obj-coff.c: added handling of `.bss` pseudo op for unitialized data. The new gcc (1.37.9x) generate these sections. .align: will use NOP_OPCODE or 0 for padding. This is just for being nice to the disassembler. * expr.c (operand): changed to generate local label "\001L0" starting with a ^A so that it is recognized as a local label. * as.c (perform_an_assembly_pass): zero bss_fix_root, too. * tc-i386.c: tc-i386.c: added handling of the following opcodes: i/o opcodes - inb, inw, outb and outw. string manipulation with att syntax - scmp, slod, smov, ssca, ssto. * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss to just after .file . In obj_crawl_symbol_chain() where it tries to put the external symbols apart, with the condition: (!S_IS_DEFINED(symbolP) && !S_IS_DEBUG(symbolP) && !SF_GET_STATICS(symbolP)) it was moving too many symbols out. So I switch it back to the condition: (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP)) In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO so that we don't use the F_RELFLG which make the linker complain that somebody has stripped the relocation info. Also, the AIX ld program require that the relocation table is sorted by r_vaddr like the standard ATT assembler does. [he also changed the sizeof(struct ...)'s into the coff style FOOSZ macros. I'm not sure this is right, but I can't remember why. xoxorich.] Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com) * Makefile.in, configure.in, doc: use the doc. Build it, install it, clean it, etc. Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com) * read.c: white space and comments only. * configure.in: use the new atof-ns32.c for ns32k. * write.c: comment change only. * tc-m88k.[hc]: pulled in from hack's unfinished work. These aren't yet integrated. * tc-i860.[hc]: blew off the dust. Something must still be done about conflicting relocation types. * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the real thing. * tc-i960.c, tc-sparc.c: white space and comments only. * tc-a29k.h: delete duplicate macro definition. * new file atof-ns32k.c copied from hack's last unreleased gas. Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com) * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work rather than abort. * nearly everything. flush ChangeLog, package as gas-1.92.1. ChangeLog's prior to this are sketchy at best. I have logs. They just aren't ChangeLogs.
