2013-04-10Improve the diagnostics of the number-reading preprocessor directives.Michael Ilseman
The GNU line marker directive was sharing code with the #line directive, but some of the warnings/errors were reporting as #line directive diagnostics in both cases. Previously: #line 11foo1 ==> "#line directive requires a simple digit sequence" # 11foo1 ==> "#line directive requires a simple digit sequence" Now, we get: #line 11foo1 ==> "#line directive requires a simple digit sequence" # 11foo1 ==> "GNU line marker directive requires a simple digit sequence" git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179139 91177308-0d34-0410-b5e6-96231b3b80d8
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
2013-04-09Remove outdated run lines from tests.Richard Trieu
These run lines originally tested that the fix-its were properly applied. Originally, the fixits were attached to warnings and were applied by -fixit. Now, the fixits are attached to notes, so nothing happens. These run lines still manage to pass since Clang will produce an empty output which gets piped back to Clang. Then Clang produces no error on an empty input. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179131 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-09[analyzer] Replace isIntegerType() with isIntegerOrEnumerationType().Jordan Rose
Previously, the analyzer used isIntegerType() everywhere, which uses the C definition of "integer". The C++ predicate with the same behavior is isIntegerOrUnscopedEnumerationType(). However, the analyzer is /really/ using this to ask if it's some sort of "integrally representable" type, i.e. it should include C++11 scoped enumerations as well. hasIntegerRepresentation() sounds like the right predicate, but that includes vectors, which the analyzer represents by its elements. This commit audits all uses of isIntegerType() and replaces them with the general isIntegerOrEnumerationType(), except in some specific cases where it makes sense to exclude scoped enumerations, or any enumerations. These cases now use isIntegerOrUnscopedEnumerationType() and getAs<BuiltinType>() plus BuiltinType::isInteger(). isIntegerType() is hereby banned in the analyzer - lib/StaticAnalysis and include/clang/StaticAnalysis. :-) Fixes real assertion failures.

2013-04-08<rdar://problem/13584715> Converted constant expressions are expected to ↵Douglas Gregor
have integral values. We were assuming that any expression used as a converted constant expression would either not have a folded constant value or would be an integer, which is not the case for some ill-formed constant expressions. Because converted constant expressions are only used where integral values are expected, we can simply treat this as an error path. If that ever changes, we'll need to widen the interface of Sema::CheckConvertedConstantExpression() anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@179068 91177308-0d34-0410-b5e6-96231b3b80d8
