[Qemu-devel] [PATCH v2 3/5] target-tricore: Added new MOV instruction variant

[Bastian Koppelmann <kbastian@mail.uni-paderborn.de>]

From: Peer Adelt <peer.adelt@c-lab.de>

Puts the content of data register D[a] into E[c][63:32] and the
content of data register D[b] into E[c][31:0].

[BK: fix style error]
