I already have: include/linux/compiler.h
/* * "Define 'is'", Bill Clinton * "Define 'if'", Steven Rostedt */ #define if(cond, ...) __trace_if( (cond , ## __VA_ARGS__) ) #define __trace_if(cond) \ if (__builtin_constant_p((cond)) ? !!(cond) : \ ({ \ int ______r; \ static struct ftrace_branch_data \ __attribute__((__aligned__(4))) \ __attribute__((section("_ftrace_branch"))) \ ______f = { \ .func = __func__, \ .file = __FILE__, \ .line = __LINE__, \ }; \ ______r = !!(cond); \ ______f.miss_hit[______r]++; \ ______r; \ }))
