42f6ed91 JS |
103 | * @set_pc: Callback for setting the Program Counter register. This |
104 | * should have the semantics used by the target architecture when | |
105 | * setting the PC from a source such as an ELF file entry point; | |
106 | * for example on Arm it will also set the Thumb mode bit based | |

5b24c641 | 117 | * @gdb_core_xml_file: File name for core registers GDB XML description. |
2472b6c0 PM |
118 | * @gdb_stop_before_watchpoint: Indicates whether GDB expects the CPU to stop |
119 | * before the insn which triggers a watchpoint rather than after it. | |
b3820e6c DH |
120 | * @gdb_arch_name: Optional callback that returns the architecture name known |
121 | * to GDB. The caller must free the returned string with g_free. | |
200bf5b7 AB |
122 | * @gdb_get_dynamic_xml: Callback to return dynamically generated XML for the |
