7:
8: * messages.c New function: as_bad This is like as_warn, except
9: -W doesn't disable it, and calling it inhibits production of an
10: object file and causes a non-zero exit code.
11:
12: Tue Feb 13 14:25:53 EST 1990 hack@wookumz
13: * Makefile Include G0 and LOADLIBES for Sequent Symmetry.

33:
34:
35: Wed Jan 3 09:35:31 EST 1990 [email protected]

43:
44: * ns32k.c (md_create_{long,short}_jump) Six line patch from

62:
63: * expr.c Replace the generic_buffer hack with a more portable one */
64:
65: * atof-generic.c (atof_generic) Ignore trailing zeroes after a decimal

213:
214: * sparc.c (comment_chars[]): Removed '|' because it was causing
215: problems. Probably not the best fix, since I suspect other

499: * m68k-opcode.h: Made "fmovep a0@, fp0" work.
500:
501: (In version 1.12)
502:
503: * write.c: Fixed an obscure bug in relaction that would occasionally
504: cause the assembler to stop relaxing when it really had at least one
505: more pass to do.
506:
507: (In version 1.11)
508:
509: * m68k*: Allow register lists in fmovem.

518: values over 10^16 or so.
519:
520: (In version 1.09)

523:
524: (In version 1.08)
525:
526: * m68k.c, m68k-opcode.h: Added support for fmovem with register lists.
527:
528: * Fixed an obscure bug having to do with generating PC-relative
529: addressing mode for things in the middle of the instruction instead of
530: at the end.

544:
545: * Added patches from pace to files as.h i386.c i386-opcode.h
546: imull foo,%eax no longer gets assembled into the 32-64 bit
547: multiply, which clobbers %edx behind gcc's back
548:
549: jcxz/jecxz were backwards
550:
551: There was a bug when using %ebp as a base register with no
552: displacement
553:
554: Instructions like andb $0xffffff, %al used to put out too many
555: immediate bytes
556:
557: The splitting jump instructions across frags could happen when
558: obstack_room()==6 too.
