Re: [tree-ssa] where to fix this?
I should add that there are a few cases where the language *does* want to
control the optimization aspects of folding, although most of the problems
require some parser state to be kept track of separately rather than the
language controlling folding. For example, bug 7284: signed left shift is
implementation-defined in C90 but undefined in C99, and this is the sort
of optimization that front ends need to be able to control.
