* softfloat: decrease MIN_EXP to cover full float rangeAndreas Cadhalpun2016-11-251-1/+1
| | | | | | | | floats are not necessarily normalized, so a normalized softfloat needs MIN_EXP lowered by 23 to cover that range. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

* softfloat: handle INT_MIN correctly in av_int2sfAndreas Cadhalpun2015-11-081-1/+6
| | | | | | | | Otherwise v=INT_MIN doesn't get normalized and thus triggers av_assert2 in other functions. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
