.`gdb` is rebased to version 16.3 This update of `gdb` to version 16.3 in RHEL 9.7 provides the following notable enhancements: * Removed support for Intel MPX. * Added support for tagged data pointers, including Intel's Linear Address Masking (LAM) and aarch64's Memory Tagging Extension (MTE). * Enabled background DWARF reading for improved performance. * Enhanced Intel Process Trace (`record btrace`): ** Asynchronous event printing enabled with `set record btrace pt event-tracing`. ** Ptwrite payloads can now be accessed in Python as `RecordAuxiliary` objects. * Improved Python integration: ** Stop events now include a `details` attribute, mirroring MI "*stopped" events. ** `gdb.Progspace()` no longer creates objects directly; objects must be obtained with other APIs. ** User-defined attributes can be added to `gdb.Inferior` and `gdb.InferiorThread` objects. ** Introduced new event source: `gdb.tui_enabled`. ** Added `gdb.record.clear`, which clears the current recording’s trace data. ** Added modules for handling missing objfiles and debug information. ** New class `gdb.missing_debug.MissingDebugInfo` can be subclassed to handle missing debug information. ** New attribute `gdb.Symbol.is_artificial`. ** New constants for symbol lookup across multiple domains. ** New function `gdb.notify_mi(NAME, DATA)` emits custom async notifications. ** New attribute `gdb.Value.bytes` for reading and writing value contents. ** Added `gdb.interrupt` to simulate a CTRL-C interrupt. ** New attribute `gdb.InferiorThread.ptid_string` provides the target ID. * Debug Adapter Protocol (DAP) changes: ** Updated "scopes" request to include global variables and the last return value. ** "launch" and "attach" requests can be used at any time, effective after "configurationDone". ** "variables" request no longer returns artificial symbols. ** Added "process" event and support for the "cancel" request. ** "attach" request now supports specifying the program. * Introduced new commands for styling, language frame mismatch warnings, missing objfile handlers, and function call timeouts. * Enhanced and renamed several commands, including improved error handling for `disassemble` and renaming `set unwindonsignal` to `set unwind-on-signal`. * Expanded remote packet support, including new packets for file status and memory fetch, and new stop reasons such as `clone`. * Introduced per-thread event reporting options and address tagging checks.
