+ 12(%esp) Arg# 3

+
+ The following code tries hard to be optimal. A general assumption
+ (which is true according to the data books I have) is that
+
+ 2 * xchg is more expensive than pushl + movl + popl
+
+ Beside this a neat trick is used. The calling conventions for Linux
+ tell that among the registers used for parameters %ecx and %edx need
+ not be saved. Beside this we may clobber this registers even when
+ they are not used for parameter passing.
+
+ As a result one can see below that we save the content of the %ebx
+ register in the %edx register when we have less than 3 arguments
+ (2 * movl is less expensive than pushl + popl).
+
+ Second unlike for the other registers we don't save the content of
+ %ecx and %edx when we have more than 1 and 2 registers resp.
+
+ The code below might look a bit long but we have to take care for
+ the pipelined processors (i586). Here the `pushl' and `popl'
+ instructions are marked as NP (not pairable) but the exception is
+ two consecutive of these instruction. This gives no penalty on
+ other processors though. */
