Akira Hatanaka	50a81ea2bc	Don't apply lvalue-to-rvalue conversion in DefaultLValueConversion to the expression that is passed to it if it has a function type or array type lvalue-to-rvalue conversion should only be applied to non-function, non-array types, but clang was applying the conversion to discarded value expressions of array types. rdar://problem/61203170 Differential Revision: https://reviews.llvm.org/D78134	2020-05-13 20:12:10 -07:00
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
Aaron Ballman	78ecb8737d	No longer emit diagnostics about unused results (comparisons, etc) from unevaluated contexts. Fixes PR18571. llvm-svn: 219954	2014-10-16 20:13:28 +00:00
