OK, so if I understand well the problem that "gcc doesn't unroll nested loops"
exists only for C++, not for C ? That seems so strange to me, but then again I
don't know much about compilers.
So now I need to make a decision for my C++ project. I am planning to unfold
nested loops into normal loops, for instance replace
for( col = 0; col < size(); col++)
for( row = 0; row < size(); row++)
{
...
}
with
for( int foo = 0; foo < size() * size(); foo++)
{
col = foo / size();
row = foo % size();
...
}
Do you think this will help solve my problem? Do you see a better solution?
