Optimization

[Robert Thomas]

Can you provide some insight into what the -fcombine_statics
optimization flag does and what impact removing it will have on our
code.

We are compiling with 2.7.2 and when we use either -O2 or -O3 we get
internal compiler errors.  Through some playing around it aws found that
removing the -fcombine_statics flag after specifying -O3 things compile
fine.

We need to be able to justify this reduction in optimization as a
'non-issue'. However, we are unclear what exactly we are losing by
removing this flag.

Can you provide any insight into this or perhaps direct me so the
correct place to ask?

Thanks in advance
Rob
