...which usually calls a
platform-specific version via _enc->opt_vtable.fdct8x8, though on some
platforms, it will call a specific version directly (e.g.,
oc_enc_fdct8x8_x86_64sse2 on x86-64). All of the functions with
platform-specific accelerated versions work like this. If you want to
force oc_enc_fdct8x8_c (the unaccelerated version) to be called, then
build without assembly optimizations enabled (e.g., pass --disable-asm
to configure).
