The one-register-and-modified-immediate forms left the op bit and the Q
bit out of their masks. Those two bits are the whole difference between
VMOV and VMVN and between the D and Q widths, so a handful of D-form
entries answered for words that were neither -- a Q-width VMOV decoded
as a D-width VMVN. With them pinned the matrix has to be complete, and
it was not: only four of the ten cmodes had Q forms at all. Both
mnemonics now carry the full set, with cmode 1110 going to VMOV.I64
rather than VMVN when op is set, and cmode 1111 belonging to VMOV
alone.
VLDM and VSTM name their addressing mode, as LDM and STM do, so they
are VLDMIA and VLDMDB rather than one mnemonic apiece -- and the
decrement-before forms, which always write back, had no entries at all.
The broadcast structure loads are not mnemonics of their own. VLD2R and
friends are how the encoding is named, not how it is written: an
assembler writes `vld2.8 {d0[], d1[]}, [r0]`, a VLD2 with an all-lanes
list. They join VLD2, VLD3 and VLD4 as the forms they are, and the list
carries the spacing bit 5 gives it.
VFMA against bfloat16 names which half of each pair it takes on the
mnemonic, bottom or top. It had one form covering the top half under
the plain name and none for the bottom.
Every word the A32 sweep produces now round-trips through llvm-mc or is
one llvm's own disassembly cannot: 985 exact, 177 with no assemblable
text, 38 reserved, and PSB CSYNC and TSB CSYNC, which llvm does not
implement for AArch32.
