[PATCH 2/2] target/ppc: Check DEXCR on hash{st, chk} instructions

Adds checks to the hashst and hashchk instructions to only execute if enabled by the relevant aspect in the DEXCR and HDEXCR. This behaviour is guarded behind TARGET_PPC64 since Power10 is currently the only implementation which has the DEXCR. Signed-off-by: Nicholas Miehlbradt --- target/ppc

[PATCH 0/2] target/ppc: Implement Dynamic Execution Control Registers

aspects can be manipulated but have no effect on execution. Adds checks to these registers in the hashst and hashchk instructions so that they are executed as nops when not enabled. Nicholas Miehlbradt (2): target/ppc: Implement the DEXCR and HDEXCR target/ppc: Check DEXCR on hash{st, chk
