The fbstp implementation fails to check for out-of-range and invalid values, instead just taking the result of conversion to int64_t and storing its sign and low 18 decimal digits. Fix this by checking for an out-of-range result (invalid conversions always result in INT64_MAX or INT64_MIN from the softfloat code, which are large enough to be considered as out-of-range by this code) and storing the packed BCD indefinite encoding in that case. Backports commit 374ff4d0a3c2cce2bc6e4ba8a77eaba55c165252 from qemu |
