2011-09-30Some fixes for MS-style asm parsing: specifically, add some error checking, ↵Eli Friedman
and handle asm comments using semicolons correctly. (The comments are actually surprisingly tricky.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140837 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-29Mark the ExtWarn for in-class initialization of static const float members ↵Richard Smith

2011-09-29constexpr: semantic checking for constexpr variables.Richard Smith
We had an extension which allowed const static class members of floating-point type to have in-class initializers, 'as a C++0x extension'. However, C++0x does not allow this. The extension has been kept, and extended to all literal types in C++0x mode (with a fixit to add the 'constexpr' specifier). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140801 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-29Add support for alignment-specifiers in C1X and C++11, removePeter Collingbourne

2011-09-29Add an ns_bridged attribute, used to specify that a John McCall
pointer to the annotated struct type can be used as an Objective-C object pointer. If an argument is given, the type is actually "toll-free bridged" to the specific type named there, rather than just to 'id'. For now, we cannot rely on all types being so annotated, and we'll always have to have exceptions for things like CFTypeRef (aka const void*), but this is clearly a good foundation for improving toolage in this area. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140779 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Like IBOutletCollection, it only makes sense to apply the IBOutlet ↵Ted Kremenek
annotation to Objective-C object types. Fixes <rdar://problem/10142685>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140778 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-29Basic/Diagnostic: Kill off a few unnecessary functions now that refactoring ↵Daniel Dunbar
is done, and add a note that the new setDiagnosticGroup{...} methods only operate on the current diagnostic state. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140771 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Rewrite DiagnosticIDs::getDiagnosticLevel completely to ↵Daniel Dunbar
be straighter line code, use the new DiagnosticMappingInfo flags, and eliminate the odd MAP_WARNING_NO_WERROR and friend mappings. - This fixes a host of obscure bugs with regards to how warning mapping options composed with one another, and I believe makes the code substantially easier to read and reason about. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140770 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Add three explicit bits to DiagnosticMappingInfo to track ↵Daniel Dunbar
"no-warning-as-error", "no-error-as-fatal", and "show-in-system-header", and update DiagnosticsEngine::setDiagnosticGroup{WarningAsError,ErrorAsFatal} and GetDefaultDiagMappingInfo to set them appropriately. - No actual functionality change for now, we still also use the diag::Mapping::{MAP_WARNING_NO_ERROR,MAP_ERROR_NO_FATAL,MAP_WARNING_SHOW_IN_SYSTEM_HEADER} for a little while longer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140768 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Add a DiagnosticIDs::getDiagnosticsInGroup method, and useDaniel Dunbar
that in DiagnosticEngine instead of the convoluted calling into DiagnosticIDs which then calls back into the DiagnosticsEngine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140766 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostic: Add a DiagSate::getOrAddMappingInfo method.Daniel Dunbar
- Also, spell const_iterator as const_iterator. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140765 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140764 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Move setDiagnosticMapping() to using DiagnosticMappingInfoDaniel Dunbar
and eliminate setDiagnosticMappingInternal. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140763 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Add a DiagnosticMappingInfo helper class, and switch toDaniel Dunbar
storing mappings with that instead of straying some magic constants about the source. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140760 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Eliminate getDiagnosticMappingInfo method, which wasn't ↵Daniel Dunbar
worth methodizing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140759 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostic: Eliminate the extra "mapping" out-parameter now that I ↵Daniel Dunbar
killed the sole client. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140756 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Add an isDefaultMappingAsError method, and switch ↵Daniel Dunbar
TextDiagnosticPrinter to use that instead of extracting the current mapping via getDiagnosticLevel, which fixes one class of corner cases w.r.t. printing the "-Werror" diagnostic option marker. - The TextDiagnosticPrinter code is still fragile as it is just "reverse engineering" what the diagnostic engine is doing. Not my current priority to fix though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140752 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-29Basic/Diagnostic: Factor outDaniel Dunbar
DiagnosticsEngine::setDiagnosticGroup{ErrorAsFatal,WarningAsError} methods which more accurately model the correct API -- no internal change to the diagnostics engine yet though. - Also, stop honoring -Werror=everything (etc.) as a valid (but oddly behaved) option. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140747 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-29Introduce a pure virtual clone() method to DiagnosticConsumer, so thatDouglas Gregor
we have the ability to create a new, distict diagnostic consumer when we go off and build a module. This avoids the currently horribleness where the same diagnostic consumer sees diagnostics for multiple translation units (and multiple SourceManagers!) causing all sorts of havok. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140743 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Basic/Diagnostics: Split out the default warning "no-Werror" andDaniel Dunbar
"show-in-system-header" bits, which is part of teasing them apart from the diagnostic mapping kind. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140742 91177308-0d34-0410-b5e6-96231b3b80d8
