- arguments 4, 5, and 6.)
-
- 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. */
