The recently added store_pair_lanes causes ICEs in output_operand.
This is due to aarch64_classify_address treating it like a 128-bit STR
rather than a STP. The valid immediate offsets don't fully overlap,
causing it to return false. Eg. offset 264 is a valid 8-byte STP offset
but not a valid 16-byte STR offset since it isn't a multiple of 16.
The original instruction isn't passed in the printing code, so the context
is unclear. The solution is to add a new operand formatting specifier
which is used for LDP/STP instructions like this. This, like the Uml
constraint that applies to store_pair_lanes, uses PARALLEL when calling
aarch64_classify_address so that it knows it is an STP.
Also add the 'z' specifier for future use by load/store pair instructions.
gcc/
* config/aarch64/aarch64.c (aarch64_print_operand): Add new
cases for printing LDP/STP memory addresses.
(aarch64_print_address_internal): Renamed from
aarch64_print_operand_address, added parameter, add Pmode check.
(aarch64_print_ldpstp_address): New function for LDP/STP addresses.
(aarch64_print_operand_address): Indirect to
aarch64_print_address_internal.
* config/aarch64/aarch64-simd.md (store_pair_lanes): Use new
'y' operand output specifier.

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.
