* config/avr/avr-arch.h (avr_mcu_t): Add dev_attribute field to have device
specific ISA/ feature information. Remove short_sp and errata_skip ds.
Add avr_device_specific_features enum to have device specific info.
* config/avr/avr-c.c (avr_cpu_cpp_builtins): use dev_attribute to check
errata_skip. Add __AVR_ISA_RMW__ builtin macro if RMW ISA available.
* config/avr/avr-devices.c (avr_mcu_types): Update AVR_MCU macro for
updated device specific info.
* config/avr/avr-mcus.def: Merge device specific details to
dev_attribute field.
* config/avr/avr.c (avr_2word_insn_p): use dev_attribute field to check
errata_skip.
* config/avr/avr.h (AVR_HAVE_8BIT_SP): same for short sp info.
* config/avr/driver-avr.c (avr_device_to_as): Pass -mrmw option to
assembler if RMW isa supported by current device.
* config/avr/genmultilib.awk: Update as device info structure changed.
* doc/invoke.texi: Add info for __AVR_ISA_RMW__ builtin macro
* gcc.target/avr/dev-specific-rmw.c: New test.

This directory contains the GNU Compiler Collection (GCC).
The GNU Compiler Collection is free software. See the files whose
names start with COPYING for copying permission. The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.
The directory INSTALL contains copies of the installation information
as HTML and plain text. The source of this information is
gcc/doc/install.texi. The installation information includes details
of what is included in the GCC sources and what files GCC installs.
See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information. An online readable
version of the manual is in the files gcc/doc/gcc.info*.
See http://gcc.gnu.org/bugs/ for how to report bugs usefully.
Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
