VDSP35<>21065L

Started by Jens Michaelsen August 9, 2004
Hello members,

trying hard to port a complete C-applikation
from VDSP-2.0 to VDSP-3.5. Doing things like:
- Boot up System
- Init some Io-Ports
- emulate SPI and TWI interface via software.
- capture 48kHz two channel audio via IIS.

All fine, as long as I do not
switch on the optimizers.

- I have plenty of external Stack and Heap memory
- I do NOT make braindead pointer stuff
just some plain floating point routines.

Using VDSP-3.5 with official patches from June.
Running under Windows 2000 in VmWare 4.5 Box.

Small projekts seem to work fine.
My complete application fails.
Things compile but execute strange. Looks
like relevant statements get optimzed out.
Sometimes loops crach after second iteration.(??)
Results are different when I compile all in one
big file (not realy modular...).

Did I miss an update??
Any better compiler revision to use??

ThanX
