2019-12-09Fix libdecnumber handling of non-canonical BID significands (PR ↵Joseph Myers1-3/+19
middle-end/91226). As reported in bug 91226, the libdecnumber code used on the host to interpret DFP values in the BID encoding fails, for _Decimal64 and _Decimal128, to check for the case where a significand is too large and so specified in IEEE 754 to be a non-canonical encoding of the zero significand. This patch adds the required handling of that case, together with tests both using -O2 (testing this host code) and -O0 (testing libgcc code, which already worked before the patch); the tests also cover _Decimal32, which already had the required check. In the _Decimal128 case, where the code previously completely ignored the case where the first four bits of the combination field are 1100, 1101 or 1110, the logic for determining the correct quantum exponent in that case is also newly added by this patch, so tests are added for that as well (again, libgcc already handled it correctly when the conversion was done at runtime rather than at compile time). Bootstrapped with no regressions for x86_64-pc-linux-gnu. PR middle-end/91226 libdecnumber: * bid/bid2dpd_dpd2bid.c (_bid_to_dpd64): Handle non-canonical significands. (_bid_to_dpd128): Likewise.
