[Qemu-devel] [PATCH v6 20/37] target-arm: Implement ARMv8 MVFR registers

2014-04-10 Thread Peter Maydell
For ARMv8 there are two changes to the MVFR media feature registers: * there is a new MVFR2 which is accessible from 32 bit code * 64 bit code accesses these via the usual sysreg instructions rather than with a floating-point specific instruction Implement this. Signed-off-by: Peter Maydell
