2013-03-11Document changes to the record target resulting from the renaming intoMarkus Metzger4-34/+220
record-full. Document two new record sub-commands "record instruction-history" and "record function-call-history" and two associated set/show commands "set record instruction-history-size" and "set record function-call-history-size". Add this to NEWS. gdb/ * NEWS: Add record changes. doc/ * gdb.texinfo (Process Record and Replay): Document record changes.
2013-03-11Add a disassembly flag to omit the pc prefix and use it in the "recordMarkus Metzger4-1/+15
instruction-history" command of record-btrace. The pc prefix would appear multiple times in the branch trace disassembly, which is more confusing than helpful. gdb/ * record-btrace.c (btrace_insn_history): Omit the pc prefix in the instruction history disassembly. * disasm.c (dump_insns): Omit the pc prefix, if requested. * disasm.h (DISASSEMBLY_OMIT_PC): New.
2013-03-11Add a target for branch trace recording.Markus Metzger4-2/+704
The target implements the new record sub-commands "record instruction-history" and "record function-call-history". The target does not support reverse execution or navigation in the recorded execution log. gdb/ * Makefile.in (SFILES): Add record-btrace.c (COMMON_OBS): Add record-btrace.o * record-btrace.c: New. * objfiles.c: Include btrace.h. (free_objfile): call btrace_free_objfile.

This is about the same as the previous patch. Functions that take or return ascii-ish string arguments usually use char* for parameters/return. That means that at points we call into target methods that work with binary blobs, we need casts to/from gdb_byte*/char*.
