#369 missing symbol INT123_dct36_sse_wrap when configured with --with-cpu=sse_alone

[Ozkan Sezer]

The issue shows itself best if you add -Wl,--no-undefined to LDFLAGS:

This seems to be because of r5396, and there is an OPT_MULTI confusion: OPT_MULTI is not defined in this build, but OPT_THE_DCT36 and thus DCT36_WRAP are only defined if OPT_MULTI is defined.

[Thomas Orgis]

Yes, I reverted that change. The indirect branch on aarch64 is the bogus thing here. No OPT_THE_DCT36 and thus no wrappers for single optimizations.

[Thomas Orgis]

(sorry)

[Ozkan Sezer]

OK, this can be closed.
