ARMv8.2 adds two new instructions: BFC as an alias for BFM and REV64 as an alias for REV. This patch set adds support for these to binutils, enabled when the -march=armv8.2-a is given. It depends on the support for an instruction being its preferred form which was added in an earlier patch. This patch adds the alias BFC <Rd>, #<imm>, #<width> as the preferred form for BFM when the source is a zero register and the conditions for using the BFI form are met (in other words, BFC is the preferred form for BFI <Rd>, <Rs>, #<imm>, #<width> when the <Rs> is a zero register). gas/testsuite/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * gas/aarch64/alias-2.d: New. * gas/aarch64/alias-2.s: New. include/opcode/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64.h (aarch64_op): Add OP_BFC. opcodes/ 2015-11-27 Matthew Wahab <matthew.wahab@arm.com> * aarch64-asm-2.c: Regenerate. * aarch64-asm.c (convert_bfc_to_bfm): New.
