+* 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.
+
+* New command line option -mtune=[itanium1|itanium2] for IA64 targets.
+
+Changes in 2.16:
+
+* Redefinition of macros now results in an error.
+
+* New command line option -mhint.b=[ok|warning|error] for IA64 targets.
+
+* New command line option -munwind-check=[warning|error] for IA64
+ targets.
+
+* The IA64 port now uses automatic dependency violation removal as its default
+ mode.
+
+* Port to MAXQ processor contributed by HCL Tech.
+
+* Added support for generating unwind tables for ARM ELF targets.
+
+* Add a -g command line option to generate debug information in the target's
+ preferred debug format.
+
+* Support for the crx-elf target added.
+
+* Support for the sh-symbianelf target added.
+
+* Added a pseudo-op (.secrel32) to generate 32 bit section relative relocations
+ on pe[i]-i386; required for this target's DWARF 2 support.
+
* Support for Motorola MCF521x/5249/547x/548x added.
* Support for ColdFire EMAC instructions added and Motorola syntax for MAC/EMAC
instrucitons.
+* New command line option -mno-shared for MIPS ELF targets.
+
+* New command line option --alternate and pseudo-ops .altmacro and .noaltmacro
+ added to enter (and leave) alternate macro syntax mode.
+
+Changes in 2.15:
+
* The MIPS -membedded-pic option (Embedded-PIC code generation) is
deprecated and will be removed in a future release.
