# Abstract:
#
#   OS X Application requires 16 byte stack alignment. The problem is these
#   APIs are exposed to code that does not have this requirement via 
#   EFI_UNIX_THUNK_PROTOCOL. So these are wrapper functions that make sure
#   the stack is aligned. This code should also work if the stack is already
#   aligned. Extra stack padding is really the same as local varaibles so 
#   it gets freed by the leave instruction
#
# I basically used the compiler, added extra 16 bytes to the local stack and
# made sure %esp ended in 0 before the call (16 byte algined)
#
# cat t.c
##include <stdio.h>
##include <sys/stat.h>
#
#int chmod (int fd, mode_t len){
#  long m = (long)fd;
#}
#
#int Gasketchmod (int fd, mode_t len){
#  return chmod (fd, len);
#}
#
# gcc -S t.c
# cat t.s
# this gives you the starting point....
