[Qemu-devel] [PATCH 0/2] two tcg improvements

[Richard Henderson]

The first patch allows the x86-64 port to avoid the REX.W prefix
on moves, by allowing reg-reg moves to be typed just as reg-imm
moves already are.  This does require trivial changes to each port.

The second patch fixes an oversight in commit
  86feb1c860dc38e9c89e787c5210e8191800385e
whereby I only modified the 32-bit host versions of the inline
functions and not the 64-bit host versions.  This is visible on
x86-64 host with arm guest in that we unnecessarily emit some
MOVSLQ insns instead of plain 32-bit MOV insns.

Richard Henderson (2):
  tcg: Add TYPE parameter to tcg_out_mov.
  tcg: Use INDEX_op_qemu_ld32 for 32-bit results.
