aarch64: Add support for sve2p1 pmov instruction.
This patch adds support for followign SVE2p1 instruction, spec is available here [1].
1. PMOV (to vector)
2. PMOV (to predicate)
Both pmov (to vector) and pmov (to predicate) have destination scalable vector
register and source scalable vector register respectively as an operand with no
suffix and optional index. To handle this case we have added 8 new operands in
this patch.
AARCH64_OPND_SVE_Zn0_INDEX, /* Zn[index], bits [9:5]. */
AARCH64_OPND_SVE_Zn1_17_INDEX, /* Zn[index], bits [9:5,17]. */
AARCH64_OPND_SVE_Zn2_18_INDEX, /* Zn[index], bits [9:5,18:17]. */
AARCH64_OPND_SVE_Zn3_22_INDEX, /* Zn[index], bits [9:5,18:17,22]. */
AARCH64_OPND_SVE_Zd0_INDEX, /* Zn[index], bits [4:0]. */
AARCH64_OPND_SVE_Zd1_17_INDEX, /* Zn[index], bits [4:0,17]. */
AARCH64_OPND_SVE_Zd2_18_INDEX, /* Zn[index], bits [4:0,18:17]. */
AARCH64_OPND_SVE_Zd3_22_INDEX, /* Zn[index], bits [4:0,18:17,22]. */
Since the index of the <Zd> operand is optional, the index part is
dropped in disassembly in both the cases of "no index" or "zero index".
As per spec: PMOV <Zd>{[<imm>]}, <Pn>.D
PMOV <Pn>.D, <Zd>{[<imm>]}
Example1:
Assembly: pmov z5[0], p6.d
Disassembly: pmov z5, p6.d
Assembly: pmov z5, p6.d
Disassembly: pmov z5, p6.d
Example2:
Assembly: pmov p4.b, z5[0]
Disassembly: pmov p4.b, z5
Assembly: pmov p4.b, z5
Disassembly: pmov p4.b, z5
