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. */ /* Comment this out to get assertion checking. */ #define NDEBUG /* Change this to "#define TRACE(x) x" for some diagnostics. */ #define TRACE(x) #include #include #include "EXTERN.h" #include "perl.h" #include "XSUB.h" #include "patchlevel.h" #include "mpir.h" /* Perl 5.005 doesn't have SvIsUV, only 5.6 and up.

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). */ int use_sv (SV *sv) { double d; if (SvGMAGICAL(sv)) { mg_get(sv); if (SvPOKp(sv)) return USE_PVX; if (SvIOKp(sv)) { if (SvIsUV(sv)) { if (SvNOKp(sv)) goto u_or_n; return USE_UVX; } else { if (SvNOKp(sv)) goto i_or_n; return USE_IVX; } } if (SvNOKp(sv)) return USE_NVX; goto rok_or_unknown; } if (SvPOK(sv)) return USE_PVX; if (SvIOK(sv)) { if (SvIsUV(sv)) { if (SvNOK(sv)) { if (PERL_LT (5, 8)) { u_or_n: d = SvNVX(sv); if (d >= ULONG_MAX_P1_AS_DOUBLE || d < 0.0) return USE_NVX; } d = SvNVX(sv); if (d != floor (d)) return USE_NVX; } return USE_UVX; } else { if (SvNOK(sv)) { if (PERL_LT (5, 8)) { i_or_n: d = SvNVX(sv); if (d >= LONG_MAX_P1_AS_DOUBLE || d < (double) LONG_MIN) return USE_NVX; } d = SvNVX(sv); if (d != floor (d)) return USE_NVX; } return USE_IVX; } } if (SvNOK(sv)) return USE_NVX; rok_or_unknown: if (SvROK(sv)) { if (sv_derived_from (sv, mpz_class)) return USE_MPZ; if (sv_derived_from (sv, mpq_class)) return USE_MPQ; if (sv_derived_from (sv, mpf_class)) return USE_MPF; } return USE_UNKNOWN; } /* Coerce sv to an mpz.
