Hi Michael,

here's a list of features and bugfixes that can serve as a basis for Monday's discussion on what we should be working on in GDB in the future.

The goal of the list is to fix currently known problems with GDB, including the testsuite, as well as bringing GDB on ARM in line with other platforms by adding required back-end support to enable common GDB features that are already supported elsewhere. It does not yet include anything completely new that we'd develop specifically for ARM.

If anybody knows of a feature or bugfix I've missed, please let me know!

Features/fixes involving kernel support: - hardware watchpoint support - Neon registers in core files - Interrupted syscall handling - PTRACE_ATTACH disabled ?

Features/fixes involving GCC support: - backtrace from abort (missing LR save) - debug info for args in varargs routine

GDB features/fixes: - prologue parsing on Thumb-2 - displaced stepping on Thumb - syscall tracing support - improved epilogue detection (fix software watchpoints) - multi-threaded debugging inferior crashes - multi-threaded Thumb/ARM state tracking - signal handler stepping - inferior call fixes - misc. other testsuite regressions

gdbserver features/fixes - Neon register support - fast tracepoints

Mit freundlichen Gruessen / Best Regards

Ulrich Weigand
