+* ARC backend accepts .extInstruction, .extCondCode, .extAuxRegister, and
+ .extCoreRegister pseudo-ops that allow an user to define custom
+ instructions, conditional codes, auxiliary and core registers.

* Add a configure option --enable-elf-stt-common to decide whether ELF
assembler should generate common symbols with the STT_COMMON type by
default. Default to no.
