- gdb-aarch64-hw-break.patch: fix setting hardware debug registers after
fork
- Merge from fedoras gdb-7.6.50-20130731-cvs, of what will become 7.7
eventually. This includes 7.6, which gave:
* new native configurations (e.g. ARM AArch64 GNU/Linux)
* new targets (e.g. ARM AArch64, Lynx 178 PowerPC, x86_64/Cygwin)
* support for the "mini debuginfo" section, .gnu_debugdata
* the C++ ABI now defaults to the GNU v3 ABI
* more Python scripting improvements
* some GDB/MI improvements
* new configure options, new commands, and options
* new remote packets
* a new "target record-btrace" has been added while the
"target record" command has been renamed to "target record-full"
- gdb-ia64-tdep.patch: build fixes
- gdb-ppc-ptrace.diff: Remove patch, not needed on new kernels
