- * @fileoverview Turns CALLs into NOPs that are fixupable at runtime.
- *
- * Things like lock/unlock function calls can take on average 100ms.
- * Libc needs to use internal locking pervasively in order to support
- * threads. So there's a lot of cost everywhere, even though most progs
- * don't use threads. In ANSI mode we dispatching (__threaded && lock())
- * to solve this problem, but if we write lock statements that way, it
- * adds a lot of bloat to the functions that call locking routines. So
- * what we do here is replace the CALL instruction with NOP, which keeps
- * the code just as fast as inlining, while making code size 10x tinier.
