Add simple function-tracing support. Prints a message
every time the committed PC changes from one symbol scope to another. Set function_trace=y on target CPU to enable. To defer start, use function_trace_start=<tick> (in addition to setting function_trace=y). cpu/base_cpu.cc: cpu/base_cpu.hh: Add simple function-tracing support. cpu/simple_cpu/simple_cpu.cc: Add function_trace, function_trace_start params Call traceFunctions() on instruction completion cpu/simple_cpu/simple_cpu.hh: Add function_trace, function_trace_start params --HG-- extra : convert_revision : 8a7f84028ccbaee585253629007f32fc8eae35e1
