Currently, function graph tracer support have some overhead for searching the stack address of the return address(ra). we hope the PROFILE_BEFORE_PROLOGUE macro will be enabled by default in the next version of gcc, and then the overhead can be removed via hijacking the ra register directly for both non-leaf and leaf function. Thanks very much to the people in the CC list for their feedbacks, all the lastest changes goes to this git repo: git://dev.lemote.com/rt4ls.git linux-mips/dev/ftrace-upstream Welcome to play with it and give more feedbacks.
