Strange behaviour of gcc for ADSP21060?

Hello Netters,

We are facing a problem with gcc (cross compiler for ADSP21060 of Anlog
Devices that runs on PC). For different optimisation levels, the compiler
uses different registers/no registers for passing arguments to functions.
Hence it is absolutely essential that all the files to be linked together
are compiled with the same optimisation options. If this is not done, then
the functions get wrong arguments. 

In general this kind of behaviour is definitely not acceptable because a
programmer is bound to use library routines and the compilation options
for a particular library need not be known to the programmer. 

Can somebody enlighten me about whether this is a bug or a feature?

Thanx.

Abhinav Jawadekar.
