RE: [PATCH 0/4] 'catch syscall' feature -- Introduction

  I had just one question about this:

  This patch is linux specific in its current state,
but I thought (but you are welcome to correct me if I am wrong,
as I am unsure of what follows) that other operating systems
also use syscalls (like FreeBSD or NetBSD, probably others also).

  If my previous statement is wrong, you can skip
what is following, otherwise my questions are:
1) Do all OS using syscalls use the same number to
functionality correspondence?
2) Do all OS follow the "linux" habit of never changing the
syscall numbers in changing versions?

If the answer to 2) is NO, it probably means that
extending this patch to such OS's will be harder...

Even if we stick to linux only for now,
shouldn't we explicitly add linux in the name of the processor-dependent
xml files?

This would make it easier to extend the feature to other OS's
later, no?

> source-code (as requested by Daniel Jacobowits).
> - PPC, PPC64 and i386 support.
> - Implementation of the GDB's datadir (Daniel asked this too).
