Aaron Ballman	6c93b3e29c	Adding a -Wunused-value warning for expressions with side effects used in an unevaluated expression context, such as sizeof(), or decltype(). Also adds a similar warning when the expression passed to typeid() is evaluated, since it is equally likely that the user would expect the expression operand to be unevaluated in that case. llvm-svn: 224465	2014-12-17 21:57:17 +00:00
Eli Friedman	fbc0dff6f8	Fix a couple issues where we didn't correctly delay diagnostics in PotentiallyPotentiallyEvaluated contexts. In preparation for making sizeof() PotentiallyPotentiallyEvaluated. llvm-svn: 148367	2012-01-18 01:05:54 +00:00
