opus - Sep 2013 - opus code optimization

The opus code default compiles on -o2 optimization level. I would like to
change it to -o3. I have tried doing the changes in makefile.unix . The
change is not getting reflected. I am building the code in Code composer
studio for TI processor C6000. Could anybody help me with this

I'm not familiar with Code Composer, but the website says it's based on
eclipse. Is there an compiler settings tab in the project properties
dialog which has an effect?

Our upstream source doesn't include support for Code Composer, so you'll
have to figure out how your IDE is driving the build. If it was calling
out to Makefile.unix changing that file should have had an effect. Since
it didn't, I would guess it's either calling the autotools build, or you
have a custom project file.

If there's a .cproject in your source tree you can share I might be able
to figure out which it is from that.

Sorry not to be more help,

Hello,
I have attached a makefile that will build the OPUS library for
a TI-c64+ core.
If you are targeting a FIXED_POINT architecture,
the file celt/fixed_c6x.h has an unbalanced '#if 0' statement -
just add a '#endif' to fix it so that the build completes.

Change the OP_FLAGS macro to suit your optimization needs.

give it a try, or modify if your target is a different C6000 core.
