+ * June 27, 2001 Manuel Novoa III
+ *
+ * This is a heavily modified version of gcc's output for the _syscall5 macro.
+ * The idea (originally from dietlibc) is that all syscall functions simply set
+ * the syscall number as the first argument, then set the syscall arguments as
+ * the next up-to-five arguments, and then jump here. All the common work is
+ * done by syscall(), saving a fair amount of generated code when a number of
+ * syscalls are used. The (potential) cost is some unnecessary pushes, pops,
+ * and movs but the execution time penalty should be relatively small compared
+ * to the cost of the syscall itself.
+ *
+ * July 24, 2002
+ *
+ * Modified by Erik Andersen to take all function parameters from off the stack
+ * like a proper function and eliminates the old 255 syscall number limit. So
+ * now we can just call this as a function as syscall() per the function
+ * prototype in unistd.h, so to call _exit(42) you can just call.
+ * syscall(__NR_exit, 42);
+ * and things will just work.

+ 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'

+ two consecutive of these instruction. This gives no penalty on
