FFmpeg/tests/checkasm/hevc_idct.c
Andreas Rheinhardt 3f82b38516 tests/checkasm/hevc_*: Avoid using declare_func_emms where possible
Only the idct_dc and add_residual functions have MMX versions,
so one can use the version with the stricter check (that checks
that the MMX registers have not been clobbered) for all the other
checks.
