[PATCH v8 09/19] gdbstub: Change gdb_get_reg_cb and gdb_set_reg_cb |
|
Date: |
Sat, 16 Sep 2023 17:01:26 +0900 |
Align the parameters of gdb_get_reg_cb and gdb_set_reg_cb with the
gdb_read_register and gdb_write_register members of CPUClass to allow
to unify the logic to access registers of the core and coprocessors
in the future.
