Add a disassembly flag to omit the pc prefix and use it in the "record
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.
