2016-11-25softfloat: decrease MIN_EXP to cover full float rangeAndreas Cadhalpun
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>
2016-11-15softfloat: handle -INT_MAX correctlyAndreas Cadhalpun

2015-11-08softfloat: handle INT_MIN correctly in av_int2sfAndreas Cadhalpun
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>
2015-11-08softfloat: assert when the argument of av_sqrt_sf is negativeAndreas Cadhalpun
The correct result can't be expressed in SoftFloat. Currently it returns a random value from an out of bounds read. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

2008-08-31Globally rename the header inclusion guard names.Stefano Sabatini
Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk
