|
* The .type pseudo-op now accepts a type of STT_GNU_IFUNC which can be used to
|
|
|
|
|
indicate that if the symbol is the target of a relocation, its value should
|
|
|
|
|
not be use. Instead the function should be invoked and its result used as
|
|
|
|
|
the value.

|
|
|
|
|
adds compatibility with H'00 style hex constants.
|
|
|
|
|
|
2008-04-10 19:53:40 +02:00

|
|
|
|
* New sub-option added to the assembler's -a command line switch to
|
|
|
|
|
generate a listing output. The 'g' sub-option will insert into the listing
|
|
|
|
|
various information about the assembly, such as assembler version, the
|
|
|
|
|
command line options used, and a time stamp.

|
|
|
|
|
|
2007-07-03 13:01:12 +02:00
|
|
|
|

|
2002-06-29 06:54:59 +02:00
|
|
|
|
|
2007-07-03 13:01:12 +02:00
|
|
|
|
Changes in 2.17:
|
|
|
|
|
|
2006-02-17 15:36:28 +01:00
|
|
|
|
* Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
|
|
|
|
|
|
2005-11-08 12:17:03 +01:00
|
|
|
|

|
|
|
|
|
2005-10-25 19:42:02 +02:00
|
|
|
|
* Support for the Z80 processor family has been added.
|
|
|
|
|
|
2005-10-13 02:57:43 +02:00
|
|

|
|
|
|
|
switches can be read from <file>.
|
|
|
|
|
|
2005-10-06 13:44:07 +02:00
|
|
|
|
* The SH target supports a new command line switch --enable-reg-prefix which,
|
|
|
|
|
if enabled, will allow register names to be optionally prefixed with a $
|
|
|
|
|
character. This allows register names to be distinguished from label names.
|
|
|
|
|
|
2005-05-06 08:50:31 +02:00
|
|
|
|
* Macros with a variable number of arguments are now supported. See the
|
|
|
|
|
documentation for how this works.
|
|
|
|
|
|
2005-04-12 10:42:41 +02:00
|
|
|
|
* Added --reduce-memory-overheads switch to reduce the size of the hash
|
|
|
|
|
tables used, at the expense of longer assembly times, and
|
|
|
|
|
--hash-size=<NUMBER> to set the size of the hash tables used by gas.
|
|
|
|
|
|
2005-04-11 14:46:38 +02:00
|
|
|
|
* Macro names and macro parameter names can now be any identifier that would
|
|
|
|
|
also be legal as a symbol elsewhere. For macro parameter names, this is
|
|
|
|
|
known to cause problems in certain sources when the respective target uses
|
|
|
|
|
characters inconsistently, and thus macro parameter references may no longer
|
|
|
|
|
be recognized as such (see the documentation for details).
|
2005-04-12 10:42:41 +02:00
|
|
|
|
|
2005-04-01 16:17:17 +02:00

|
|
assembler.
|
|
|
|
|

targets.
|
|
|
|
|
|
2005-02-14 09:02:51 +01:00
|
|
|
|
* The IA64 port now uses automatic dependency violation removal as its default
|
|
|
|
|
mode.
|
|
|
|
|
|
2004-11-08 14:17:43 +01:00

|
|
|
|
|
preferred debug format.
|
|
|
|
|
|
2004-07-07 19:28:53 +02:00
|
|
|
|
* Support for the crx-elf target added.

2004-07-07 19:28:53 +02:00
|
|
|
|
|
2004-05-07 16:44:56 +02:00
|
|
|
|
* Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
|
|
|
|
|
on pe[i]-i386; required for this target's DWARF 2 support.
|
|
|
|
|
|
2004-05-05 16:33:14 +02:00
|
|
|
|
* Support for Motorola MCF521x/5249/547x/548x added.
|
|
|
|
|
|

|
|
|
|
* Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
|
|
|
|
|
instrucitons.
|
|
|
|
|
|
2004-12-10 20:48:21 +01:00

|
|
|
|
|
|
2004-08-13 21:53:52 +02:00
|
|
|
|
* New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
|
|
|
|
|
added to enter (and leave) alternate macro syntax mode.
|
|
|
|
|
|
2004-07-13 19:31:15 +02:00
|
|
|
|
Changes in 2.15:
|
|
|
|
|
|
2004-04-21 02:44:36 +02:00

2003-12-05 02:59:55 +01:00
|
|
|
|

|
|
|
|
|
specification has been added to the arm assembler.
|
2003-11-14 09:21:02 +01:00
|
|
|
|
|
* config/tc-arm.texi (struct reg_entry): Add new field 'builtin'.
(rn_table, iwmmxt_table, cp_table, cn_table, fn_table, sn_table,
dn_table, mav_mvf_table, mac_mvd_table, mav_mvfx_table,
mav_mvax_table, mav_dspc_table): Initialise new field.
(insert_reg_alias): Initialise new field.

2003-11-06 16:30:05 +01:00
|
|
|
|
* On ARM architectures, added a new gas directive ".unreq" that undoes
|
|
|
|
|
definitions created by ".req".
|
|
|
|
|
|
2003-10-21 15:28:59 +02:00
|
|
|
|
* Support for Motorola ColdFire MCF528x added.

|
|
|
|
2003-06-10 08:46:34 +02:00

|
* Added -n switch for x86 assembler. By default, x86 GAS replaces
|
|
|
|
|
multiple nop instructions used for alignment within code sections
|
|
|
|
|
with multi-byte nop instructions such as leal 0(%esi,1),%esi. This
|
|
|
|
|
switch disables the optimization.
|
|
|
|
|
|
2004-01-09 03:34:04 +01:00
|
|
|
|
* Removed -n option from MIPS assembler. It was not useful, and confused the
|
|
|
|
|
existing -non_shared option.
|
|
|
|
|
|
2003-09-30 18:44:04 +02:00

1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* i386/PowerPC gnu-win32 support added.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* m88k-motorola-sysv3* support added.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
Changes in 2.6:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Gas now directly supports macros, without requiring GASP.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Added --defsym SYM=VALUE option.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Added -mips4 support to MIPS assembler.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Added PIC support to Solaris and SPARC SunOS 4 assembler.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
Changes in 2.4:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Converted this directory to use an autoconf-generated configure script.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* ARM support, from Richard Earnshaw.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Updated VMS support, from Pat Rankin, including considerably improved
|
|
|
|
|
debugging support.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Support for the control registers in the 68060.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Usage message is available with "--help".
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Weak symbol support for a.out.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by
|
|
|
|
|
Paul Kranenburg.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Improved Alpha support. Immediate constants can have a much larger range
|
|
|
|
|
now. Support for the 21164 has been contributed by Digital.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Updated ns32k (pc532-mach, netbsd532) support from Ian Dall.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
Changes in 2.3:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Mach i386 support, by David Mackenzie and Ken Raeburn.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* RS/6000 and PowerPC support by Ian Taylor.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Irix 5 support.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
Changes in 2.2:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* RS/6000 AIX and MIPS SGI Irix 5 support has been added.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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".
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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).
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS
|
|
|
|
|
support is in progress.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
Changes in 2.1:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been
|
|
|
|
|
incorporated, but not well tested yet.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Altered the opcode table split for m68k; it should require less VM to compile
|
|
|
|
|
with gcc now.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Some minor adjustments to add (Convergent Technologies') Miniframe support,
|
|
|
|
|
suggested by Ronald Cole.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* HP9000/300 support, donated by HP, has been merged in.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Better error messages for unsupported configurations (e.g., hppa-hpux).
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Test suite framework is starting to become reasonable.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
Changes in 2.0:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Mostly bug fixes.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Some more merging of BFD and ELF code, but ELF still doesn't work.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
|
|
|
|
Changes in 1.94:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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.)
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* The 68K opcode table has been split in half. It should now compile under gcc
|
|
|
|
|
without consuming ridiculous amounts of memory.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* A couple data structures have been reduced in size. This should result in
|
|
|
|
|
saving a little bit of space at runtime.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* 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 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* Support for the Hitachi H8/500 has been added.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* VMS host and target support should be working now, thanks chiefly to Eric
|
|
|
|
|
Youngdale.
|
1999-05-03 09:29:11 +02:00
|

Changes in 1.93.01:
|
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* For m68k, support for more processors has been added: 68040, CPU32, 68851.
|
1999-05-03 09:29:11 +02:00
|
|
|
|
|
2002-07-19 09:52:40 +02:00
|
|
|
|
* For i386, .align is now power-of-two; was number-of-bytes.
|
1999-05-03 09:29:11 +02:00
