[PATCH 05/15] target/arm: Implement CLRM instruction

2020-11-16 Thread Peter Maydell
In v8.1M the new CLRM instruction allows zeroing an arbitrary set of the general-purpose registers and APSR. Implement this. The encoding is a subset of the LDMIA T2 encoding, using what would be Rn=0b (which UNDEFs for LDMIA). Signed-off-by: Peter Maydell --- target/arm/t32.decode | 6 +
