[Qemu-devel] [PATCH v2 14/15] target-tricore: Add instructions of SLR, SSRO and SRO opcode format |
Date: |
Mon, 14 Jul 2014 18:41:10 +0100 |
Add instructions of SLR, SSRO and SRO opcode format.
Signed-off-by: Bastian Koppelmann <address@hidden>
---
v1 -> v2:
- Add one decode function for all SLR instructions.
- Add one decode function for all SRO instructions.
- Remove duplicate SSRO instructions, which were removed in patch v1 15/15.
- Change load/store to use TCGMemOp.
