middle-end/112296 - __builtin_constant_p and side-effects
The following tries to clarify the __builtin_constant_p documentation,
stating that the argument expression is not evaluated and side-effects
are discarded. I'm struggling to find the correct terms matching
what the C language standard would call things so I'd appreciate
some help here.
OK for trunk?
Shall we diagnose arguments with side-effects? It seems to me
such use is usually unintended? I think rather than dropping
side-effects as a side-effect of folding the frontend should
discard them at parsing time instead, no?
Thanks,
Richard.
