2012-04-05Improve diagnostics for invalid use of non-static members / this:Richard Smith
* s/nonstatic/non-static/ in the diagnostics, since the latter form outvoted the former by 28-2 in our diagnostics. * Fix the "use of member in static member function" diagnostic to correctly detect this situation inside a block or lambda. * Produce a more specific "invalid use of non-static member" diagnostic for the case where a nested class member refers to a member of a lexically-surrounding class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154073 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-05Fix assertions and wrong output from StmtPrinter's string literal printing.Richard Smith
String literals (including unicode ones) can contain non-Unicode codepoints if they were written using \x or similar. Write those out using \x, but be careful that the following character can't be misinterpreted as part of the \x escape sequence. Convert UTF-16 surrogate pairs back to codepoints before rendering them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154069 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-05Enable warn_impcast_literal_float_to_integer by default.David Blaikie
This diagnostic seems to be production ready, it's just an oversight that it wasn't turned on by default. The test changes are a bit of a mixed bag. Some tests that seemed like they clearly didn't need to use this behavior have been modified not to use it. Others that I couldn't be sure about, I added the necessary expected-warnings to. It's possible the diagnostic message could be improved to make it clearer that this warning can be suppressed by using a value that won't lose precision when converted to the target type (but can still be a floating point literal, such as "bool b = 1.0;"). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154068 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-04Adds a tooling library.Manuel Klimek
Provides an API to run clang tools (FrontendActions) as standalone tools, or repeatedly in-memory in a process. This is useful for unit-testing, map-reduce style applications, source transformation daemons or command line tools. The ability to run over multiple translation units with different command line arguments enables building up refactoring tools that need to apply transformations across translation unit boundaries. See tools/clang-check/ClangCheck.cpp for an example. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154008 91177308-0d34-0410-b5e6-96231b3b80d8

a type specifier and can be combined with unsigned. This allows libstdc++4.7 to be used with clang in c++98 mode. Several other changes are still required for libstdc++4.7 to work with clang in c++11 mode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153999 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-04When performing template argument deduction for an initializer list,Douglas Gregor
be sure to perform the argument type adjustments in [temp.deduct.call]p2, e.g., array decay. And, when performing these deductions in the context of 'auto', make sure that we're deducing the P' in std::initializer_list<P'> rather than the whole initializer list. Together, this makes code like for( auto s : {"Deferred", "New", "Open", "Review"}) { } work properly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153998 91177308-0d34-0410-b5e6-96231b3b80d8
