[MC][ARM] vscclrm disassembles as vldmia
Happens only when the mve.fp subtarget feature is enabled:
$ llvm-mc -triple thumbv8.1m.main -mattr=+mve.fp,+8msecext -disassemble <<< "0x9f,0xec,0x08,0x0b"
.text
vldmia pc, {d0, d1, d2, d3}
$ llvm-mc -triple thumbv8.1m.main -mattr=+8msecext -disassemble <<< "0x9f,0xec,0x08,0x0b"
.text
vscclrm {d0, d1, d2, d3, vpr}
Assembling returns the correct encoding with or without mve.fp:
$ llvm-mc -triple thumbv8.1m.main -mattr=+mve.fp,+8msecext -show-encoding <<< "vscclrm {d0-d3, vpr}"
.text
vscclrm {d0, d1, d2, d3, vpr} @ encoding: [0x9f,0xec,0x08,0x0b]
$ llvm-mc -triple thumbv8.1m.main -mattr=+8msecext -show-encoding <<< "vscclrm {d0-d3, vpr}"
.text
vscclrm {d0, d1, d2, d3, vpr} @ encoding: [0x9f,0xec,0x08,0x0b]
The problem seems to be in the TableGen description of VSCCLRMD.
The least significant bit should be set to zero.
