Add a new modifier /c to the "record function-call-history" command to indent the function name based on its depth in the call stack. Also reorder the optional fields to have the indentation at the very beginning. Prefix the insn range (/i modifier) with "inst ". Prefix the source line (/l modifier) with "at ". Change the range syntax from "begin-end" to "begin,end" to allow copy&paste to the "record instruction-history" and "list" commands. Adjust the respective tests and add new tests for the /c modifier. 2014-01-16 Markus Metzger <markus.t.metzger@intel.com> * record.h (enum record_print_flag) <record_print_indent_calls>: New. * record.c (get_call_history_modifiers): Recognize /c modifier. (_initialize_record): Document /c modifier. * record-btrace.c (btrace_call_history): Add btinfo parameter. Reorder fields. Optionally indent the function name. Update all users. * NEWS: Announce changes. testsuite/ * gdb.btrace/function_call_history.exp: Fix expected field order for "record function-call-history". Add new tests for "record function-call-history /c". * gdb.btrace/exception.cc: New. * gdb.btrace/exception.exp: New. * gdb.btrace/tailcall.exp: New. * gdb.btrace/x86-tailcall.S: New. * gdb.btrace/x86-tailcall.c: New. * gdb.btrace/unknown_functions.c: New. * gdb.btrace/unknown_functions.exp: New. * gdb.btrace/Makefile.in (EXECUTABLES): Add new. doc/ * gdb.texinfo (Process Record and Replay): Document new /c modifier accepted by "record function-call-history". Add /i modifier to "record function-call-history" example.
