* Fix conversions to long double on sparc64jca2019-06-212-12/+12
| | | | | | | | | | | | | | | | | | | | | | | Bug exposed by erratic sqlite3 behavior used in ports/devel/proj, as pointed out by landry@. Richard Hipps (SQLite) pointed at the culprit (_Qp_div), many thanks. Adapted from FreeBSD revision 146673 by Stephen Paskaluk and stefanf@FreeBSD. FreeBSD commit message: """ Fix long (and long long) to long double, unsigned to long double and unsigned long (and unsigned long long) to long double conversions. - Add a parameter that specifies the position of the sign bit to the _QP_TTOQ macro, previously it always looked at bit 31. Pass a negative number to disable sign inspection for unsigned types. This fixes _Qp_xtoq(), _Qp_uitoq() and _Qp_uxtoq(). - In the functions __fpu_itof() and __fpu_xtof(), look at the sign bit to decide whether we're doing a conversion from an unsigned type. If so, don't negate the mantissa if the integer exceeds the biggest signed number. """ ok deraadt@

| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@
