|
* Added -n switch for x86 assembler. By default, x86 GAS replaces
|
|
|
|
|
multiple nop instructions used for alignment within code sections

2002-02-21 16:51:00 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* GASP now correctly parses floating point numbers. Unless the base is
|
|
|
|
|
explicitly specified, they are interpreted as decimal numbers regardless of
|
|
|
|
|
the currently specified base.
|

|
|
|
|
|
specifying the target instruction set. The old method of specifying the
|
|

|
|
target processor has been deprecated, but is still accepted for
|
|
|
|
|
compatibility.
|

|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The MIPS assembler no longer issues a warning by default when it
|
|
|
|
|
generates a nop instruction from a macro. The new command line option
|
|
|
|
|
-n will turn on the warning.

|
|
|
|
* picoJava architecture support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Motorola MCore 210 processor support added.
|
1999-09-04 17:29:22 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386
|
|
|
|
|
assembly programs with intel syntax.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Added -gdwarf2 option to generate DWARF 2 debugging information.
|
1999-09-04 17:29:22 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Full 16-bit mode support for i386.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Greatly improved instruction operand checking for i386. This change will
|
|
|
|
|
produce errors or warnings on incorrect assembly code that previous versions
|
|
|
|
|
of gas accepted. If you get unexpected messages from code that worked with
|
|
|
|
|
older versions of gas, please double check the code before reporting a bug.

Changes in 2.9:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Texas Instruments c30 (tms320c30) support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The assembler now optimizes the exception frame information generated by egcs
|
|
|
|
|
and gcc 2.8. The new --traditional-format option disables this optimization.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Added --gstabs option to generate stabs debugging information.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The -a option takes a new suboption, m (e.g., -alm) to expand macros in a
|
|
|
|
|
listing.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Added -MD option to print dependencies.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
|
|
|
|
Changes in 2.8:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* BeOS support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* MIPS16 support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Motorola ColdFire 5200 support added (configure for m68k and use -m5200).
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Alpha/VMS support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* m68k options --base-size-default-16, --base-size-default-32,
|
|
|
|
|
--disp-size-default-16, and --disp-size-default-32 added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The alignment directives now take an optional third argument, which is the
|
|
|
|
|
maximum number of bytes to skip. If doing the alignment would require
|
|
|
|
|
skipping more than the given number of bytes, the alignment is not done at
|
|
|
|
|
all.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The ELF assembler has a new pseudo-op, .symver, used for symbol versioning.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The -a option takes a new suboption, c (e.g., -alc), to skip false
|
|
|
|
|
conditionals in listings.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Added new pseudo-op, .equiv; it's like .equ, except that it is an error if
|
|
|
|
|
the symbol is already defined.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
|
|
|
|
Changes in 2.7:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The PowerPC assembler now allows the use of symbolic register names (r0,
|
|
|
|
|
etc.) if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.)
|
|
|
|
|
can be used any time. PowerPC 860 move to/from SPR instructions have been
|
|
|
|
|
added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Alpha Linux (ELF) support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* PowerPC ELF support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* m68k Linux (ELF) support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* i960 Hx/Jx support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* i386/PowerPC gnu-win32 support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the
|
|
|
|
|
default is to build COFF-only support. To get a set of tools that generate
|
|
|
|
|
ELF (they'll understand both COFF and ELF), you must configure with
|
|
|
|
|
target=i386-unknown-sco3.2v5elf.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* m88k-motorola-sysv3* support added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
|
|
|
|
Changes in 2.6:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Gas now directly supports macros, without requiring GASP.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Gas now has an MRI assembler compatibility mode. Use -M or --mri to select
|
|
|
|
|
MRI mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the
|
|
|
|
|
``.mri 0'' is seen; this can be convenient for inline assembler code.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Added --defsym SYM=VALUE option.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Added -mips4 support to MIPS assembler.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Added PIC support to Solaris and SPARC SunOS 4 assembler.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
|
|
|
|
Changes in 2.4:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Converted this directory to use an autoconf-generated configure script.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* ARM support, from Richard Earnshaw.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Updated VMS support, from Pat Rankin, including considerably improved
|
|
|
|
|
debugging support.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Support for the control registers in the 68060.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to
|
|
|
|
|
provide for possible future gcc changes, for targets where gas provides some
|
|
|
|
|
features not available in the native assembler. If the native assembler is
|
|
|
|
|
used, it should become obvious pretty quickly what the problem is.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Usage message is available with "--help".
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3
|
|
|
|
|
also, but didn't get into the NEWS file.)
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Weak symbol support for a.out.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* A bug in the listing code which could cause an infinite loop has been fixed.
|
|
|
|
|
Bugs in listings when generating a COFF object file have also been fixed.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
|
|
|
|
|
Paul Kranenburg.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Improved Alpha support. Immediate constants can have a much larger range
|
|
|
|
|
now. Support for the 21164 has been contributed by Digital.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
|
|
|
|
Changes in 2.3:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Mach i386 support, by David Mackenzie and Ken Raeburn.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* RS/6000 and PowerPC support by Ian Taylor.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit,
|
|
|
|
|
based on mail received from various people. The `-h#' option should work
|
|
|
|
|
again too.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work
|
|
|
|
|
with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special
|
|
|
|
|
version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve
|
|
|
|
|
this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu
|
|
|
|
|
in the "dist" directory.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Vax support in gas fixed for BSD, so it builds and seems to run a couple
|
|
|
|
|
simple tests okay. I haven't put it through extensive testing. (GNU make is
|
|
|
|
|
currently required for BSD 4.3 builds.)
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is
|
|
|
|
|
based on code donated by CMU, which used an a.out-based format. I'm afraid
|
|
|
|
|
the alpha-a.out support is pretty badly mangled, and much of it removed;
|
|
|
|
|
making it work will require rewriting it as BFD support for the format anyways.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Irix 5 support.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The test suites have been fixed up a bit, so that they should work with a
|
|
|
|
|
couple different versions of expect and dejagnu.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Symbols' values are now handled internally as expressions, permitting more
|
|
|
|
|
flexibility in evaluating them in some cases. Some details of relocation
|
|
|
|
|
handling have also changed, and simple constant pool management has been
|
|
|
|
|
added, to make the Alpha port easier.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* New option "--statistics" for printing out program run times. This is
|
|
|
|
|
intended to be used with the gcc "-Q" option, which prints out times spent in
|
|
|
|
|
various phases of compilation. (You should be able to get all of them
|
|
|
|
|
printed out with "gcc -Q -Wa,--statistics", I think.)
|
1999-05-03 07:29:11 +00:00

Changes in 2.2:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* RS/6000 AIX and MIPS SGI Irix 5 support has been added.

* Configurations that are still in development (and therefore are convenient to
|
|
|
|
|
have listed in configure.in) still get rejected without a minor change to
|
|
|
|
|
gas/Makefile.in, so people not doing development work shouldn't get the
|
|
|
|
|
impression that support for such configurations is actually believed to be
|
|
|
|
|
reliable.

|
|
|
|
* The program name (usually "as") is printed when a fatal error message is
|
|
|
|
|
displayed. This should prevent some confusion about the source of occasional
|
|
|
|
|
messages about "internal errors".

2002-07-19 07:52:40 +00:00
|
|
|
|
* ELF support is falling into place. Support for the 386 should be working.
|
|
|
|
|
Support for SPARC Solaris is in. HPPA support from Utah is being integrated.

|
|
|
|
* Symbol values are maintained as expressions instead of being immediately
|
|
|
|
|
boiled down to add-symbol, sub-symbol, and constant. This permits slightly
|
|
|
|
|
more complex calculations involving symbols whose values are not alreadey
|
|
|
|
|
known.

2002-07-19 07:52:40 +00:00
|
|
|
|
* DBX-style debugging info ("stabs") is now supported for COFF formats.
|
|
|
|
|
If any stabs directives are seen in the source, GAS will create two new
|
|
|
|
|
sections: a ".stab" and a ".stabstr" section. The format of the .stab
|
|
|
|
|
section is nearly identical to the a.out symbol format, and .stabstr is
|
|
|
|
|
its string table. For this to be useful, you must have configured GCC
|
|
|
|
|
to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB
|
|
|
|
|
that can use the stab sections (4.11 or later).

|
|
|
|
* LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS
|
|
|
|
|
support is in progress.

Changes in 2.1:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
|
|
|
|
|
incorporated, but not well tested yet.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Altered the opcode table split for m68k; it should require less VM to compile
|
|
|
|
|
with gcc now.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Some minor adjustments to add (Convergent Technologies') Miniframe support,
|
|
|
|
|
suggested by Ronald Cole.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* HPPA support (running OSF only, not HPUX) has been contributed by Utah. This
|
|
|
|
|
includes improved ELF support, which I've started adapting for SPARC Solaris
|
|
|
|
|
2.x. Integration isn't completely, so it probably won't work.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* HP9000/300 support, donated by HP, has been merged in.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Better error messages for unsupported configurations (e.g., hppa-hpux).
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Test suite framework is starting to become reasonable.

Changes in 2.0:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Mostly bug fixes.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Some more merging of BFD and ELF code, but ELF still doesn't work.
|
1999-05-03 07:29:11 +00:00

Changes in 1.94:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* BFD merge is partly done. Adventurous souls may try giving configure the
|
|
|
|
|
"--with-bfd-assembler" option. Currently, ELF format requires it, a.out
|
|
|
|
|
format accepts it; SPARC CPU accepts it. It's the default only for OS "elf"
|
|
|
|
|
or "solaris". (ELF isn't really supported yet. It needs work. I've got
|
|
|
|
|
some code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not
|
|
|
|
|
fully merged yet.)
|

|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* The 68K opcode table has been split in half. It should now compile under gcc
|
|
|
|
|
without consuming ridiculous amounts of memory.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* A couple data structures have been reduced in size. This should result in
|
|
|
|
|
saving a little bit of space at runtime.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF
|
|
|
|
|
code provided ROSE format support, which I haven't merged in yet. (I can
|
|
|
|
|
make it available, if anyone wants to try it out.) Ralph's code, for BSD
|
|
|
|
|
4.4, supports a.out format. We don't have ECOFF support in just yet; it's
|
|
|
|
|
coming.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Support for the Hitachi H8/500 has been added.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* VMS host and target support should be working now, thanks chiefly to Eric
|
|
|
|
|
Youngdale.

Changes in 1.93.01:
|
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* For m68k, support for more processors has been added: 68040, CPU32, 68851.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* For i386, .align is now power-of-two; was number-of-bytes.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* For m68k, "%" is now accepted before register names. For COFF format, which
|
|
|
|
|
doesn't use underscore prefixes for C labels, it is required, so variable "a0"
|
|
|
|
|
can be distinguished from the register.
|
1999-05-03 07:29:11 +00:00
|
|
|
|
|
2002-07-19 07:52:40 +00:00
|
|
|
|
* Last public release was 1.38. Lots of configuration changes since then, lots
|
|
|
|
|
of new CPUs and formats, lots of bugs fixed.
