[Speex-dev] DSP c5x

[Jean-Marc Valin]

Hi, (trying to get back in touch with the rest of the world)

You shouldn't use ENABLE_VALGRIND unless you're actually debugging using
valgrind. As for reducing the encoder/decoder stack, you can usually
decrease that value when you're not using high complexity settings. If
your compiler supports C99 variable arrays or a non-braindead alloca,
you can try the code in svn and define either VAR_ARRAYS or USE_ALLOCA.
Note however that this is still experimental and may break.

As for the remaining float values when you define FIXED_POINT, it's
because not all the code has been completely converted to fixed-point.
There are still some float operations left in e.g. initialization and
packet loss concealment.
