Make the array interface 64-bit safe by using SSize_t instead of I32
for array indices.
This is based on a patch by Chip Salzenberg.
This completes what the previous commit began when it changed
av_extend.

For threaded platforms, this reduces the object code size significantly, and
should slightly reduce CPU usage.

Add Perl v5.6 compatibility code to FastCalc.xs (Closes RT #63859).

Remove _new() from XS code and use _new() in Math::BigInt::Calc
instead. The XS _new() doesn't handle integers that are too large to
be represented exactly as floating point numbers, but small enough
to be represented as 64 bit integers. E.g., even with 64 bit integer
support, applying _num() to 18446744073709551615 (= 2**64-1) gives
1.84467440737096e+19, not 18446744073709551615. The XS _new() also
returns nan, not inf, when it overflows. This closes RT #63335 and
RT #49569.

croak_xs_usage is new in perl 5.10, but some version xsubpp emulate it on older
perls as well. However, really old xsubpps don't do that.

This makes applying patches between them easier.

The variables are neither documented nor exported, and nothing on CPAN uses
them. Hence there is no need to set them, which means that the return list from
Math::BigInt::Calc::_base_len() can be passed directly into FastCalc's XS
bootstrap.
|
| |
|
|
|
| |
The BEGIN context of the code C<use>ing it will be early enough for the
subroutine assignments to take full effect.
|
| |
|
|
|
|
| |
This avoids the need for a separate, special, one-shot _set_XS_BASE routine.
We take advantage of the fact that all arguments to XSLoader::load() are passed
on to the module's bootstrap routine.
|
| |
|
|
|
| |
A search of CPAN shows that this private function is only used internally
between Math::BigInt::Calc, Math::BigInt::FastCalc and their test suites.

Previously these were using AV *. Whilst the code always was managing
references correctly, to work around the deficiency of the standard typemap
entry for AV * it had to mortalise the array it created, meaning that it was
creating 2 entries per call on the mortals stack, not 1.

As the minimum perl version is 5.006, enable 'use warnings'.

With the previous commit, both are now only used in one place.
No need to use sv_2mortal() on the reset of boolSV(), as both PL_sv_no and
PL_sv_yes are immortals. [And special-cased within the implementation of
sv_2mortal() - not only is it a no-op, it's a non-free no-op :-)]

_one, _two and _ten are aliases to _zero
_is_odd is an alias of _is_even
_is_one, _is_two, _is_ten are aliases of _is_zero
On this system this reduces the object code size by about 4.5K (about 20%).
