The tables that are used take 256B; the code to initialize them uses
281B here (GCC 9.3, x64, -O3, but in av_cold functions). On top of that,
removing this code also allows to remove the array of AVOnce used to
guard the cosine tables against multiple initializations; this also
removes
There are three types of FFTs: floating-point, 32-bit fixed-point and
16-bit fixed-point. The latter has exactly one user: The fixed-point
AC-3-encoder; the cosine tables used by it use up to seven bits. The
tables corresponding to eight to seventeen bits are unused, as are the
FFT functions for
The fixed point FFT never uses the 32bit revtab; this commit adds
some compile-time checks to make sure that dead code doesn't get
compiled in.
Also, while just at it, fix the indentation in ff_fft_init() and make sure
that a do {} while (0) macro does not already swallow the semicolon on its
tableprint.h does not declare anything as aligned; it just prints
DECLARE_ALIGNED. So it can be removed; in fact, it needs to be removed,
because mem_internal.h includes config.h which leads to warnings when
building with hardcoded tables enabled because of redefinitions of
