Dear all, Please help me
my code works without optimization. but when I set it to file level (o3)
optimization it doesn't work and it remains for allways in the following
while loop. when I investigated the code in mixed mode I saw that the
spitobyte() function is deleted in readreg() function. Even when I substituted
spitobyte() with its source code compiler deleted some parts of it and it
didn't work. Do you know why? and how can I use the code in file level
optimization without this problem?( I work with CCS3.1 and c5510 DSP)
int readreg(int i)
{
bytetospi(i);
return spitobyte();
}
...
regval=readreg(31);
while(regval)
regval=readreg(31);
...
optimization problem (file level o3)

How about you define the parameter 'volatile'? But it can also because
of other problems.
