[gas][aarch64][SVE2] Fix pmull{t,b} requirement on SVE2-AES
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. Regtested targeting aarch64-linux. gas/ChangeLog: 2019-07-01 Matthew Malcomson <matthew.malcomson@arm.com> * testsuite/gas/aarch64/illegal-sve2-aes.d: Update tests. * testsuite/gas/aarch64/illegal-sve2.l: Update tests. * doc/c-aarch64.texi: Add special note of pmull{t,b} instructions under the sve2-aes architecture extension. * testsuite/gas/aarch64/illegal-sve2.s: Add small size pmull{t,b} instructions. * testsuite/gas/aarch64/sve2.d: Add small size pmull{t,b} disassembly. * testsuite/gas/aarch64/sve2.s: Add small size pmull{t,b} instructions. include/ChangeLog: 2019-07-01 Matthew Malcomson <matthew.malcomson@arm.com> * opcode/aarch64.h (enum aarch64_insn_class): sve_size_013 renamed to sve_size_13. opcodes/ChangeLog: 2019-07-01 Matthew Malcomson <matthew.malcomson@arm.com> * aarch64-asm.c (aarch64_encode_variant_using_iclass): Use new sve_size_13 icode to account for variant behaviour of pmull{t,b}. * aarch64-dis-2.c: Regenerate. * aarch64-dis.c (aarch64_decode_variant_using_iclass): Use new sve_size_13 icode to account for variant behaviour of pmull{t,b}. * aarch64-tbl.h (OP_SVE_VVV_HD_BS): Add new qualifier. (OP_SVE_VVV_Q_D): Add new qualifier. (OP_SVE_VVV_QHD_DBS): Remove now unused qualifier. (struct aarch64_opcode): Split pmull{t,b} into those requiring AES and those not.
