- Merge from gdb-7.5.1-30.fc18.src.rpm.
7.5.1 gives:
* An "Attempt to dereference a generic pointer" errors (-var-create).
* Backtrace problems on x32 (PR backtrace/14646).
* next/step/finish problems on x32 (PR gdb/14647).
* A "malformed linespec error: unexpected keyword, [...]" error
(PR breakpoints/14643).
* GDB crash while stepping through powerpc (32bits) code.
* A failed assertion in linux_ptrace_test_ret_to_nx.
* A "!frame_id_inlined_p (frame_id)" failed assertion.
* A "No more reverse-execution history." error during reverse
"next" execution (PR 14548).
* Incomplete command descriptions in "apropos" output.
* PR gdb/14494 (a GDB crash difficult to characterize).
7.5 gives:
* Go language support.
* New targets (x32 ABI, microMIPS, Renesas RL78, HP OpenVMS ia64).
* More Python scripting improvements.
* SDT (Static Defined Tracing) probes support with SystemTap probes.
* GDBserver improvements (stdio connections, target-side evaluation
of breakpoint conditions, remote protocol improvements).
* Other miscellaneous improvements (ability to stop when a shared
library is loaded/unloaded, dynamic printf, etc).
* Reverse debugging on ARM.
- Do not provide a custom (safe) auto-load dir.
