E.g. order of eval of args to a call…if you have SSA a compiler can easily reorder to match target, no need to leave unspecified.
@samth I'd be interested in concrete examples of where the purity of an expression is hard to tell.

@pcwalton I think "function call" is the usual thing here. Lots of compilers, esp. old ones, don't do any interprocedural analysis.Thanks. Twitter will use this to make your timeline better. UndoUndo
