SBCL's internal functions
in [Lisp]

From: Bata on 14 Dec 2009 22:08 Hello, I am just learning to perform profiling on SBCL, and the statistical profiler, when run on my program, returns statistics on 2 different kinds of "+" (Addition) functions. There is one entry for sb-kernel:two-arg-+ and there is another entry for sb-vm::generic-+. I have tried looking for the differences between the two, but have so far been unsuccessful. Could someone provide me with a link for these (And other) SBCL functions? I tried looking in the manual, but didn't see any heading in there that seems close to what I am looking for. Thank you, Bata

(of course you need SBCL's sources on your system). Eg in Emacs, M-. on sb-kernel:two-arg-+ takes me to (two-arg-+/- two-arg-+ + add-bignums), above that is the macro used to define the operation. That said, I have rarely needed to look at the source of these things in SBCL. Profiling, benchmarking and compiler hints [which you can get with (declaim (optimize (speed 3))), or similar declarations for individual functions] would be the first things I consider. HTH, Tamas
