2019-07-01[gas][aarch64][SVE2] Fix pmull{t,b} requirement on SVE2-AESMatthew Malcomson1-286/+308
I had mistakenly given all variants of the new SVE2 instructions pmull{t,b} a dependency on the feature +sve2-aes. Only the variant specifying .Q -> .D sizes should have that restriction. This patch fixes that mistake and updates the testsuite to have extra tests (matching the given set of tests per line in aarch64-tbl.h that the rest of the SVE2 tests follow). We also add a line in the documentation of the command line to clarify how to enable `pmull{t,b}` of this larger size. This is needed because all other instructions gated under the `sve2-aes` architecture extension are marked in the instruction documentation by an `HaveSVE2AES` check while pmull{t,b} is gated under the `HaveSVE2PMULL128` check.

This patch is part of the patch series to add support for ARMv8.5-A Memory Tagging Extensions which is an optional extension to ARMv8.5-A and is enabled using the +memtag command line option. This patch add support to the Bulk Allocation Tag instructions from MTE. These are the following instructions added in this patch: - LDGV <Xt>, [<Xn|SP>]! - STGV <Xt>, [<Xn|SP>]! This needed a new kind of operand for the new addressing [<Xn|SP>]! since this has no offset and only takes a pre-indexed version. Hence AARCH64_OPND_ADDR_SIMPLE_2 and ldtdgv_indexed are introduced. (AARCH64_OPND_ADDR_SIMPLE fulfilled the no offset criteria but does not allow writeback). We also needed new encoding and decoding functions to be able to do the same. where <Xt> : Is the 64-bit destination GPR. <Xn|SP> : Is the 64-bit first source GPR or Stack pointer. *** include/ChangeLog *** 2018-11-12 Sudakshina Das <sudi.das@arm.com> * opcode/aarch64.h (aarch64_opnd): Add AARCH64_OPND_ADDR_SIMPLE_2.

Each of these instruction is available in both Scalar and Vector forms. Since both 1) and 2) have separate identification mechanism and it is permissible that a ARMv8.4 compliant implementation may include any arbitrary subset of the ARMv8.5 features unless otherwise specified, new feature bits are added. *** include/ChangeLog *** 2018-10-09 Sudakshina Das <sudi.das@arm.com> * opcode/aarch64.h (AARCH64_FEATURE_FLAGMANIP): New.

2018-06-29Fix AArch64 encodings for by element instructions.Tamar Christina1-69/+70
Some instructions in Armv8-a place a limitation on FP16 registers that can be used as the register from which to select an element from. e.g. fmla restricts Rm to 4 bits when using an FP16 register. This restriction does not apply for all instructions, e.g. fcmla does not have this restriction as it gets an extra bit from the M field. Unfortunately, this restriction to S_H was added for all _Em operands before, meaning for a large number of instructions you couldn't use the full register file. This fixes the issue by introducing a new operand _Em16 which applies this restriction only when paired with S_H and leaves the _Em and the other qualifiers for _Em16 unbounded (i.e. using the full 5 bit range). Also the patch updates all instructions that should be affected by this. opcodes/ PR binutils/23192 * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. * aarch64-opc-2.c: Likewise. * aarch64-dis.c (aarch64_ext_reglane): Add AARCH64_OPND_Em16 constraint. * aarch64-opc.c (operand_general_constraint_met_p, aarch64_print_operand): Likewise. * aarch64-tbl.h (aarch64_opcode_table): Change Em to Em16 for smlal, smlal2, fmla, fmls, fmul, fmulx, sqrdmlah, sqrdlsh, fmlal, fmlsl, fmlal2, fmlsl2.

2018-06-22Correct negs aliasing on AArch64.Tamar Christina1-3/+3
This patch fixes a disassembly issue with the aliases to subs with a shifted register. The subs instruction with the zero register as destination is supposed to alias to cmp and when the first input register is the zero register the subs is supposed to be aliased to negs. This means that a subs with destination and first input registers the zero register is supposed to be a cmp. This is done by raising the priority of the cmp alias. opcodes/ * aarch64-tbl.h (aarch64_opcode_table): Fix alias flag for negs * aarch64-asm-2.c: Regenerate. * aarch64-dis-2.c: Likewise. gas/ * testsuite/gas/aarch64/addsub.s: Add negs to zero reg test. * testsuite/gas/aarch64/addsub.d: Likewise.

2018-05-15Modify AArch64 Assembly and disassembly functions to be able to fail and ↵Tamar Christina1-62/+63
report why. This patch if the first patch in a series to add the ability to add constraints to system registers that an instruction must adhere to in order for the register to be usable with that instruction. These constraints can also be used to disambiguate between registers with the same encoding during disassembly. This patch adds a new flags entry in the sysreg structures and ensures it is filled in and read out during assembly/disassembly. It also adds the ability for the assemble and disassemble functions to be able to gracefully fail and re-use the existing error reporting infrastructure. The return type of these functions are changed to a boolean to denote success or failure and the error structure is passed around to them. This requires aarch64-gen changes so a lot of the changes here are just mechanical. gas/ PR binutils/21446 * config/tc-aarch64.c (parse_sys_reg): Return register flags.
