3 | # OS X Application requires 16 byte stack alignment. The problem is these\r |
| 4 | # APIs are exposed to code that does not have this requirement via \r | |
| 5 | # EFI_UNIX_THUNK_PROTOCOL. So these are wrapper functions that make sure\r | |
| 6 | # the stack is aligned. This code should also work if the stack is already\r | |
| 7 | # aligned. Extra stack padding is really the same as local varaibles so \r | |
| 8 | # it gets freed by the leave instruction\r | |
| 9 | #\r | |
| 10 | # I basically used the compiler, added extra 16 bytes to the local stack and\r | |
| 11 | # made sure %esp ended in 0 before the call (16 byte algined)\r | |
| 12 | #\r | |
| 13 | # The EFI_UNIX_THUNK_PROTOCOL member functions call a C API that then calls \r | |
| 14 | # one of these generic assembly routines. We do it that way to work around \r | |
| 15 | # some magic name changing that happens in C. For example stat() is _stat() \r | |
| 16 | # on Leopard and _stat$INDOE64 on Snow Leopard. That is why we pass stat()\r | |
| 17 | # into one of these gaskets from C code.\r | |
