* a long double or returning a double). So we can simply jump to func.
* Using __GI_func in jump to make optimized intra-library jump.
* gcc will still generate a useless "ret" after asm. Oh well...
+ *
+ * Update: we do need to use call (instead of tail jump) as gcc can create
+ * stack frame, and push/modify/pop ebx during PIC build.
+ * TODO: add conditionals to use tail jump if possible?
