[PATCH v3 4/4] target/ppc: removed all mentions to PPC_DUMP_CPU |
|
Date: |
Mon, 31 May 2021 11:56:29 -0300 |
This feature will no longer be useful as ppc moves to using decotree for
TCG. And building with it enabled is no longer possible, due to changes
in opc_handler_t. Since the last commit that mentions it happened in
2014, I think it is safe to remove it.
