+
+* Add support for the ARC EM/HS, and ARC600/700 architectures. Remove

+ if enabled, will allow register names to be optionally prefixed with a $
+ character. This allows register names to be distinguished from label names.
+
+* Macros with a variable number of arguments are now supported. See the
+ documentation for how this works.
+
+* 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.
+
+* 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).
+
+* Support the .f_floating, .d_floating, .g_floating and .h_floating directives

+ information with GNU extensions.
+
+* Added support for MIPS64 Release 2.

+* 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.
+
+* Removed -n option from MIPS assembler. It was not useful, and confused the
+ existing -non_shared option.
+
+Changes in 2.14:
+
+* Added support for MIPS32 Release 2.
+
+* Added support for Xtensa architecture.
+
+* Support for Intel's iWMMXt processor (an ARM variant) added.

+
+* Support for Don Knuth's MMIX, by Hans-Peter Nilsson.
+
+* Support for the OpenRISC 32-bit embedded processor by OpenCores.

+ specifying the target instruction set. The old method of specifying the
+ target processor has been deprecated, but is still accepted for
+ compatibility.
+
+* Support for the VFP floating-point instruction set has been added to
+ the ARM assembler.
+
+* New psuedo op: .incbin to include a set of binary data at a given point
+ in the assembly. Contributed by Anders Norlander.
+
+* The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated
+ but still works for compatability.
+

-used, it should become obvious pretty quickly what the problem is.

-too.
+* RS/6000 and PowerPC support by Ian Taylor.
-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

-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

Changes in 2.2:
-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

-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).

Changes in 1.94:
-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.)

-The 68K opcode table has been split in half. It should now compile under gcc
-without consuming ridiculous amounts of memory.

-it available, if anyone wants to try it out.) Ralph's code, for BSD 4.4,
