- /* Notes:
- Routines are grouped with the alias feature and a table of function
- pointers where possible, since each xsub routine ends up with quite a bit
- of code size. Different combinations of arguments and return values have
- to be separate though.
- The "INTERFACE:" feature isn't available in perl 5.005 and so isn't used.
- "ALIAS:" requires a table lookup with CvXSUBANY(cv).any_i32 (which is
- "ix") whereas "INTERFACE:" would have CvXSUBANY(cv).any_dptr as the
- function pointer immediately.
- Mixed-type swapped-order assignments like "$a = 123; $a += mpz(456);"
- invoke the plain overloaded "+", not "+=", which makes life easier.
- mpz_assume etc types are used with the overloaded operators since such
- operators are always called with a class object as the first argument, we
- don't need an sv_derived_from() lookup to check. There's assert()s in
- MPX_ASSUME() for this though.
- The overload_constant routines reached via overload::constant get 4
- arguments in perl 5.6, not the 3 as documented. This is apparently a
- bug, using "..." lets us ignore the extra one.
- There's only a few "si" functions in gmp, so usually SvIV values get
- handled with an mpz_set_si into a temporary and then a full precision mpz
- routine. This is reasonably efficient.
- Argument types are checked, with a view to preserving all bits in the
- operand. Perl is a bit looser in its arithmetic, allowing rounding or
- truncation to an intended operand type (IV, UV or NV).
- Bugs:
- The memory leak detection attempted in GMP::END() doesn't work when mpz's
- are created as constants because END() is called before they're
- destroyed. What's the right place to hook such a check?
- See the bugs section of GMP.pm too. */

- /* mg_get is called every time we get a value, even if the private flags are
- still set from a previous such call. This is the same as as SvIV and
- friends do.
- When POK, we use the PV, even if there's an IV or NV available. This is
- because it's hard to be sure there wasn't any rounding in establishing
- the IV and/or NV. Cases of overflow, where the PV should definitely be
- used, are easy enough to spot, but rounding is hard. So although IV or
- NV would be more efficient, we must use the PV to be sure of getting all
- the data. Applications should convert once to mpz, mpq or mpf when using
- a value repeatedly.
- Zany dual-type scalars like $! where the IV is an error code and the PV
- is an error description string won't work with this preference for PV,
- but that's too bad. Such scalars should be rare, and unlikely to be used
- in bignum calculations.
- When IOK and NOK are both set, we would prefer to use the IV since it can
- be converted more efficiently, and because on a 64-bit system the NV may
- have less bits than the IV. The following rules are applied,
- - If the NV is not an integer, then we must use that NV, since clearly
- the IV was merely established by rounding and is not the full value.
- - In perl prior to 5.8, an NV too big for an IV leaves an overflow value
- 0xFFFFFFFF. If the NV is too big to fit an IV then clearly it's the NV
- which is the true value and must be used.
- - In perl 5.8 and up, such an overflow doesn't set IOK, so that test is
- unnecessary. However when coming from get-magic, IOKp _is_ set, and we
- must check for overflow the same as in older perl.
- FIXME:
- We'd like to call mg_get just once, but unfortunately sv_derived_from()
- will call it for each of our checks. We could do a string compare like
- sv_isa ourselves, but that only tests the exact class, it doesn't
- recognise subclassing. There doesn't seem to be a public interface to
- the subclassing tests (in the internal isa_lookup() function). */
