I understand aliasing inhibits most of the classical optimizations
like PRE coomon subexpression elimination, LICM etc. So can anyone
tell me, what is the typical approach in most compilers. Are classical
optimizations disabled for all pointer variables. Does at least a
statement like p = &a get hoisted out of the loop ?
