Register handling: - Fix fetch_registers() GPR loop using loop index instead of -1 - Fix FPR index offset (subtract base register number) - Fix loop bounds: 32 registers not 31 - Gate AltiVec register access on ECF_VECTOR context flag - Implement store_registers() using IDebug->WriteTaskContext() Trap/signal handling: - Replace raw PPC vector numbers with SDK TRAPNUM_* values from exec/interrupts.h (ExceptionContext.Traptype uses these) - Add handling for TRAP_TRAP (breakpoints), TRAP_DATA_BREAKPOINT (DABR), TRAP_INST_BREAKPOINT, TRAP_TRACE (single-step) - Preserve actual signal type in wait() instead of collapsing SEGV/BUS/FPE/ILL/ALRM to generic GDB_SIGNAL_0 Process control: - Implement attach() - find task by name/address, suspend, install debug hook - Fix kill() - use Signal(SIGBREAKF_CTRL_C) + RestartTask instead of DeleteTask on Process objects Message pool safety: - Add NULL check to alloc_message() with Forbid/Permit guards - Add Forbid/Permit to free_message() for consistency - Add NULL checks to all alloc_message() calls in debug callback BFD file path fix: - Skip canonicalize_file_name() on AmigaOS in gdb_realpath() - AmigaOS realpath() resolves assigns (T: -> "RAM Disk:T/") and volume names (SYS: -> "AmigaOS:") producing paths that fail when BFD's file cache tries to reopen them Minor cleanup: - Fix typos in comments - Use gdbarch register numbers consistently
