[FFmpeg-devel] Disable inlining when using --disable-optimizations
Thu Jul 30 21:28:58 CEST 2009
When debugging issues and crashes in ffmpeg recently, I found it helpful
to have a way to disable inlining so you can get real stack frames for
each function. --disable-optimizations gets you most of the way there, but
functions marked av_always_inline will still get inlined.
Turns out there is already a case for disabling av_always_inline
(--enable-small); I extended the conditions for that to include
I've been using this for several weeks here and found it useful, so I
figured I'd post it.
When using this I noticed that the existing way of turning off
av_always_inline causes warnings of redefinition; patch
silences the warnings, too.
