+* Add support for the Renesas RX processor.
+
+Changes in 2.20:
+
+* GNU/Linux targets now supports "gnu_unique_object" as a value in the .type
+ pseudo op. It marks the symbol as being globally unique in the entire
+ process.
+
+* ARM assembler now supports .inst[.nw] pseudo-ops to insert opcodes specified
+ in binary rather than text.
+
+* Add support for common symbol alignment to PE formats.
+
+* Add support for the new discriminator column in the DWARF line table,
+ with a discriminator operand for the .loc directive.
+
+* Add support for Sunplus score architecture.
+
+* 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.
+
+* Add support for Lattice Mico32 (lm32) architecture.
+
+* Add support for Xilinx MicroBlaze architecture.
+
+Changes in 2.19:
+
+* New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
+ tables without runtime relocation.
+
+* New command line option, -h-tick-hex, for sh, m32c, and h8/300 targets, which
+ adds compatibility with H'00 style hex constants.
+
+* New command line option, -msse-check=[none|error|warning], for x86
+ targets.
+
+* 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.
+
+* New command line option -msse2avx for x86 target to encode SSE
+ instructions with VEX prefix.
+
+* Add Intel XSAVE, EPT, MOVBE, AES, PCLMUL, AVX/FMA support for x86 target.
+
+* New command line options, -march=CPU[,+EXTENSION...], -mtune=CPU,
+ -mmnemonic=[att|intel], -msyntax=[att|intel], -mindex-reg,
+ -mnaked-reg and -mold-gcc, for x86 targets.
+
+* Support for generating wide character strings has been added via the new
+ pseudo ops: .string16, .string32 and .string64.
+
+* Support for SSE5 has been added to the i386 port.
+
+Changes in 2.18:
+
+* The GAS sources are now released under the GPLv3.
+
+* Support for the National Semiconductor CR16 target has been added.
+
+* Added gas .reloc pseudo. This is a low-level interface for creating
+ relocations.
+
+* Add support for x86_64 PE+ target.
+
+* Add support for Score target.
+
+Changes in 2.17:
+
+* Support for the Infineon XC16X has been added by KPIT Cummins Infosystems.
+
+* Support for ms2 architecture has been added.
+
+* Support for the Z80 processor family has been added.
+
+* Add support for the "@<file>" syntax to the command line, so that extra
+ switches can be read from <file>.
+
+* 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.
+
+* 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
for the VAX target in order to be more compatible with the VAX MACRO
assembler.
