--- Comment #18 from Xi Ruoyao <ryxi at stu dot xidian.edu.cn> --- > Compile with '-fcilkplus -S'. According to cilkplus spec, x() should be > evaluated in the child (for the asm produced by GCC, in _cilk_spn_0). > If you find "call x" in the asm of "z" instead of "_cilk_spn_0", that version > of GCC is buggy. Note that some version of GCC put "call _cilk_enter_frame_1" in "z", before calling "x". They are good.
