* exec/configure.ac (OPEN_SYSCALL, OPENAT_SYSCALL): Define new macros. * exec/exec.h (struct exec_tracee): New field `sp'. * exec/trace.c (handle_openat): New function. (process_system_call): If handle_openat executes successfully, save the unmodified stack pointer within the tracee structure to be restored once the system call completes.
This directory holds the source code to a library used to replace the `execve' and `execveat' system calls, used by the Android port of Emacs to start executables without intervention from the system.
