[PATCH v3 04/14] target/ppc: Use env_cpu for cpu_abort in excp_helper |
|
Date: |
Fri, 16 Jun 2023 01:03:13 +0200 (CEST) |
Use the env_cpu function to get the CPUState for cpu_abort. These are
only needed in case of fatal errors so this allows to avoid casting
and storing CPUState in a local variable wnen not needed.
