| D | ftrace-design.txt | 31 You will need to implement the mcount and the ftrace_stub functions.
33 The exact mcount symbol name will depend on your toolchain. Some call it
34 "mcount", "_mcount", or even "__mcount". You can probably figure it out by
36 $ echo 'main(){}' | gcc -x c -S -o - - -pg | grep mcount
37 call mcount
38 We'll make the assumption below that the symbol is "mcount" just to keep things
41 Keep in mind that the ABI that is in effect inside of the mcount function is
46 mcount call (before/after function prologue). You might also want to look at
47 how glibc has implemented the mcount function for your architecture. It might
50 The mcount function should check the function pointer ftrace_trace_function
