I dont know what the testcase was the author encountered, i just posted
this here as the author wanted me to post it for him.
but a simple
make distclean ; ./configure --disable-ssse3 && make -j32
replicates the build failure here (see below for the errors)
We do have the
extern void RENAME(ff_yuv_420_rgb32)(x86_reg index, uint8_t *image, const
uint8_t *pu_index,
const uint8_t *pv_index, const uint64_t
*pointer_c_dither,
const uint8_t *py_2index);
...
under #if HAVE_SSSE3
so i think either that needs to be changed or the code using it needs to be
similarly protected.
the if(...)
is not good enough because it is not something failingh at linking stage but
already before because the compiler has no idea what the identifer even is.
(compared to knowing what it is but not having a implemenetation later, which
works as disabled code and optimized out references dont fail to link)
