I have a patch for this; gcc took quite some convincing that the loop bounds were correct. I'll push it tomorrow after some testing. > ratecontrol.cpp > +---- > h:/MSYS/home/LigH/x265/source/encoder/ratecontrol.cpp: In member function > 'bool x265::RateControl::initPass2()': > h:/MSYS/home/LigH/x265/source/encoder/ratecontrol.cpp:731:6: warning: > 'minVal' may be used uninitialized in this function [-Wmaybe-uninitialized] > bool RateControl::initPass2() > ^ > h:/MSYS/home/LigH/x265/source/encoder/ratecontrol.cpp:731:6: warning: > 'maxVal' may be used uninitialized in this function [-Wmaybe-uninitialized] > h:/MSYS/home/LigH/x265/source/encoder/ratecontrol.cpp:731:6: warning: 'a' > may be used uninitialized in this function [-Wmaybe-uninitialized] > h:/MSYS/home/LigH/x265/source/encoder/ratecontrol.cpp:731:6: warning: > 'minVal' may be used uninitialized in this function [-Wmaybe-uninitialized] > h:/MSYS/home/LigH/x265/source/encoder/ratecontrol.cpp:731:6: warning: > 'maxVal' may be used uninitialized in this function [-Wmaybe-uninitialized] > h:/MSYS/home/LigH/x265/source/encoder/ratecontrol.cpp:731:6: warning: 'a' > may be used uninitialized in this function [-Wmaybe-uninitialized] > +---- These I've tracked to the CLIP_DURATION() macros which map to Clip3( MIN, MAX, f ) where MIN and MAX are constant floats. I haven't the slightest clue why GCC thinks the minVal/maxVal arguments might be uninitialized, when they are constants: 0.01 and 1.00. This is gcc 4.8.1. Older versions of gcc don't seem to complain about it. -- Steve Borho _______________________________________________ x265-devel mailing list x265-devel@videolan.org https://mailman.videolan.org/listinfo/x265-devel
