trace_functions_graph.c:(.text+0x6dba0): undefined reference to `__irqentry_text_start'
trace_functions_graph.c:(.text+0x6dba8): undefined reference to `__irqentry_text_start'
trace_functions_graph.c:(.text+0x6dbd0): undefined reference to `__irqentry_text_end'
trace_functions_graph.c:(.text+0x6dbd4): undefined reference to `__irqentry_text_end'
