    • PR82809: register handling in ix86_vector_duplicate_value · a34a16ab 
      When adding the call to gen_vec_duplicate, I failed to notice that
code further down modified the VEC_DUPLICATE in place.  That isn't
safe if gen_vec_duplicate returned a const_vector.

    • combine: Print insns we try to combine · f53bd856 
      This adds some extra debug info to the dump file for combine: print
the insns that are input to try_combine.  I was worried printing more
will make the dump file only harder to read, but especially the info
from the REG_DEAD notes is invaluable.


	* combine (try_combine): Print the insns input to try_combine to the

    • [AArch64] Minor rtx costs tweak · fe1447a1 
      aarch64_rtx_costs uses the number of registers in a mode as the basis
of SET costs.  This patch makes it get the number of registers from
aarch64_hard_regno_nregs rather than repeating the calcalation inline.
Handling SVE modes in aarch64_hard_regno_nregs is then enough to get
the correct SET cost as well.

    • [AArch64] Rename the internal "Upl" constraint · ff1335e2 
      The SVE port uses the public constraints "Upl" and "Upa" to mean
"low predicate register" and "any predicate register" respectively.
"Upl" was already used as an internal-only constraint by the
addition patterns, so this patch renames it to "Uaa" ("two adds
needed").

    • [AArch64] Generate permute patterns using rtx builders · 3f8334a5 
      This patch replaces switch statements that call specific generator
functions with code that constructs the rtl pattern directly.
This seemed to scale better to SVE and also seems less error-prone.

As a side-effect, the patch fixes the REV handling for diff==1,
vmode==E_V4HFmode and adds missing support for diff==3,
vmode==E_V4HFmode.

To compensate for the lack of switches that check for specific modes,
the patch makes aarch64_expand_vec_perm_const_1 reject permutes on
single-element vectors (specifically V1DImode).

      When we have a REG_DEAD note for a reg that is set in the new I2, we
drop the note on the floor (we cannot find whether to place it on I2
or on I3).  But the code I added to do this has a bug and does not
always actually drop it.  This patch fixes it.

But that on its own is too pessimistic, it turns out, and we generate
worse code.  One case where we do know where to place the note is if
it came from I3 (it should go to I3 again).  Doing this fixes all of
the regressions.
