240 Porting to new platforms
241 ========================
243 On Unix systems, where faults are notified to the program through a signal
244 handler, the core routines in handler-unix.c can be used without
245 modifications. But they need the following bits of information. Each of
246 them is stored in a platform dependent file; the file is chosen in configure.
248   * List of signals that are sent when an invalid virtual memory address
249     is accessed, or when the stack overflows.
250     This is a file among signals-*.h.
251     configure chooses and sets the variable CFG_SIGNALS.
253   * What arguments are passed to a fault handler.
254     This is a file among fault-*.h.
255     configure chooses and sets the variable CFG_FAULT.
257   * How to determine the stack's virtual memory area.
258     This is a file among stackvma-*.c.
259     configure chooses and sets the variable CFG_STACKVMA.
261   * How to leave a signal handler that is executing on the alternate
262     signal stack.
263     This is a file among leave-*.c.
264     configure chooses and sets the variable CFG_LEAVE.
266 For each of these, the approach should be:
268   - Find a way to implement the needed functionality.  This might involve
269     study of the system include files (in particular <signal.h> and
270     <ucontext.h>) and of the kernel sources.
271     For CFG_FAULT, the best starting point is to run the tests/sigsegv1
272     program with a breakpoint set at 'sigsegv_handler'.
274   - Add to configure.in a test whether your new code works.  This will
275     help portability to platforms similar to yours.
276     Then regenerate the configure script (run "autoconf") and verify
277     that the test says "yes" on your platform.
279   - Create a platform dependent file (e.g. fault-<os>-<cpu>.h) and change
280     configure.in to choose this particular file when your test says "yes".
281     Then regenerate the configure script (run "autoconf").
283   - Verify that "make" and "make check" pass.
285 For non-Unix systems, a separate handler-<os>.c is likely to be needed.
