/* alloca.c -- allocate automatically reclaimed memory
|
||||
(Mostly) portable public-domain implementation -- D A Gwyn
|
||||
|
||||
This implementation of the PWB library alloca function,
|
||||
which is used to allocate space off the run-time stack so
|
||||
that it is automatically reclaimed upon procedure exit,
|
||||
was inspired by discussions with J. Q. Johnson of Cornell.
|
||||
J.Otto Tennant <[email protected]> contributed the Cray support.
|
||||
|
||||
There are some preprocessor constants that can
|
||||
be defined when compiling for your specific system, for
|
||||
improved efficiency; however, the defaults should be okay.
|
||||
|
||||
The general concept of this implementation is to keep
|
||||
track of all alloca-allocated blocks, and reclaim any
|
||||
that are found to be deeper in the stack than the current
|
||||
invocation. This heuristic does not reclaim storage as
|
||||
soon as it becomes invalid, but it will do so eventually.
|
||||
|
||||
As a special case, alloca(0) reclaims storage without
|
||||
allocating any. It is a good idea to use alloca(0) in
|
||||
your main control loop, etc. to force garbage collection. */

|

|
||||
1) Is this safe? Will it catch all the zero bytes?
|
||||
Suppose there is a byte with all zeros. Any carry bits
|
||||
propagating from its left will fall into the hole at its
|
||||
least significant bit and stop. Since there will be no
|
||||
carry from its most significant bit, the LSB of the
|
||||
byte to the left will be unchanged, and the zero will be
|
||||
detected.
|
||||
|
||||
2) Is this worthwhile? Will it ignore everything except
|
||||
zero bytes? Suppose every byte of LONGWORD has a bit set
|
||||
somewhere. There will be a carry into bit 8. If bit 8
|
||||
is set, this will carry into bit 16. If bit 8 is clear,
|
||||
one of bits 9-15 must be set, so there will be a carry
|
||||
into bit 16. Similarly, there will be a carry into bit
|
||||
24. If one of bits 24-30 is set, there will be a carry
|
||||
into bit 31, so all of the hole bits will be changed.
|
||||
|
||||
The one misfire occurs when bits 24-30 are clear and bit
|
||||
31 is set; in this case, the hole at bit 31 is not
|
||||
changed. If we had access to the processor carry flag,
|
||||
we could close this loophole by putting the fourth hole
|
||||
at bit 32!
|
||||
|
||||
So it ignores everything except 128's, when they're aligned
|
||||
properly.
|
||||
|
||||
3) But wait! Aren't we looking for C, not zero?
|
||||
Good point. So what we do is XOR LONGWORD with a longword,
|
||||
each of whose bytes is C. This turns each byte that is C
|
||||
into a zero. */
