2013-04-10Suppress -Wunused-variable for variables declared in headers, which may inMatt Beaumont-Gay
fact be defined and used in another TU. Reshuffle some test cases because we suppress -Wunused-variable after we've emitted an error. This fixes PR15558. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179138 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-10Fix a crash-on-invalid when parsing a reference to an invalid auto declarationDavid Blaikie
auto x((unknown)); int& y = x; would crash because we were not flagging 'x' as an invalid declaration here. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@165675 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-06Improvements to the uninitialized variable warning: Check if the constructorRafael Espindola

2011-06-21Fix PR10168: don't warn for unused non-dependent variables in both the ↵Richard Smith

2011-02-21Clean up the tests for warning about unused function results given theChandler Carruth
appropriate attribute. Add a bit more testing that finds a pretty bad regression (since ~forever) in this warning. Fix it with a nice 2 line change. =] git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126098 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-07Do not use CXXZeroValueInitExpr for class types. Instead, useDouglas Gregor
CXXConstructExpr/CXXTemporaryObjectExpr/CXXNewExpr as appropriate. Fixes PR7556, and provides a slide codegen improvement when copy-initializing a POD class type from a value-initialized temporary.

2010-02-11When we have a dependent direct initializer but not a dependentDouglas Gregor
variable type, we can (and should) still check for completeness of the variable's type. Do so, to work around an assertion that shows up in Boost's shared_ptr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95934 91177308-0d34-0410-b5e6-96231b3b80d8
