| D | ftrace-design.rst | 37 You will need to implement the mcount and the ftrace_stub functions.
39 The exact mcount symbol name will depend on your toolchain. Some call it
40 "mcount", "_mcount", or even "__mcount". You can probably figure it out by
43 $ echo 'main(){}' | gcc -x c -S -o - - -pg | grep mcount
44 call mcount
46 We'll make the assumption below that the symbol is "mcount" just to keep things
49 Keep in mind that the ABI that is in effect inside of the mcount function is
54 mcount call (before/after function prologue). You might also want to look at
55 how glibc has implemented the mcount function for your architecture. It might
58 The mcount function should check the function pointer ftrace_trace_function
