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

2011-09-27Remove the egregious hack that made Objective-C++ ARC work with olderDouglas Gregor
versions of libc++. Newer versions of libc++ know how to deal with ARC properly. Fixes <rdar://problem/10062179>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140651 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-27When 'bool' is not a built-in type but is defined as a macro, printDouglas Gregor
'bool' rather than '_Bool' within types, to make things a bit more readable. Fixes <rdar://problem/10063263>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140650 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-26Add back support for a manually formatted section of the diagnosticChandler Carruth
message. Specifically, we now only line-wrap the first line of te diagnostic message and assume the remainder is manually formatted. While adding it back, simplify the logic for doing this. Finally, add a test that ensures we actually preserve this feature. =D *Now* its not dead code. Thanks to Doug for the test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140538 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-26Hoist and beef up the asserts about the level of infrastructure expectedChandler Carruth
when working with a diagnostic attached to a source location. Also comment more thoroughly why its important to handle non-location diagnostic messages separately. Finally, hoist the creation of the TextDiagnostic object up to the beginning of the location-based diagnostics. This paves the way for sinking more and more of the logic into this class. When everything below this constructor is sunk into the TextDiagnostic class it should be sufficiently "feature complete" to accomplish my two goals: 1) Have the printing of a macro expansion note use the exact same code as any other note. 2) Be able to implement clang_formatDiagnostic in terms of this class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140526 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-26Switch the emission of diagnostics without a source location toChandler Carruth
a dedicated path. The logic for such diagnostics is much simpler than for others. This begins to make an important separation in this routine. We expect most (and most interesting) textual diagnostics to be made in the presence of at least *some* source locations and a source manager. However the DiagnosticConsumer must be prepared to diagnose errors even when the source manager doesn't (yet) exist or when there is no location information at all. In order to sink more and more logic into the TextDiagnostic class while minimizing its complexity, my plan is to force the DiagnosticConsumer to special case diagnosing any locationless messages and then hand the rest to the TextDiagnostic class. I'd appreciate any comments on this design. It requires a bit of code duplication in order to keep interfaces simple. Alternatively, if we really need TextDiagnostic to be capable of handling diagnostics even in the absence of a viable SourceManager, then this split isn't necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140525 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-26Extract the actual printing of the message string into a helperChandler Carruth
function. Doing this conveniently requires moving the word wrapping to use a StringRef which seems generally an improvement. There is a lot that could be simplified in the word wrapping by using StringRef that I haven't looked at yet... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140524 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-26Don't map a file:line:col triplet that is inside the preamble range toArgyrios Kyrtzidis
a "loaded" location of the precompiled preamble. Instead, handle specially locations of preprocessed entities: -When looking up for preprocessed entities, map main file locations inside the preamble range to a preamble loaded location. -When getting the source range of a preprocessing cursor, map preamble loaded locations back to main file locations.

2011-09-26Remove support for splitting word-wrapped diagnostic messages on newlineChandler Carruth
characters. I could find no newline character in a diagnostic message, and adding an assert to this code never fires in the testsuite. I think this code is essentially dead, and was previously used for a different purpose. If I just don't understand how it is we can end up with a newline here please let me know (with a test case?) and I'll revert. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140497 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-25Shuffle some names around. 'CaretDiagnostic' is inaccurate as this needsChandler Carruth

2011-09-25Actually remove the members of CaretDiagnostic no longer in use forChandler Carruth
tracking the start and stop of macro expansion suppression. Also remove the Columns variable which was just a convenience variable based on DiagOpts.

2011-09-25Sink the logic for suppressing some macro expansion notes from theChandler Carruth
TextDiagnosticPrinter into the CaretDiagnostic class. Several interesting results from this: - This removes a significant per-diagnostic bit of state from the CaretDiagnostic class, which should eventually allow us to re-use the object. - It removes a redundant recursive walk of the macro expansion stack just to compute the depth. We don't need the depth until we're unwinding anyways, so we can just mark when we reach it. - It also paves the way for several simplifications we can do to how we implement the suppression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140474 91177308-0d34-0410-b5e6-96231b3b80d8

This moves the existing code for CPATH into the driver and adds the environment lookup and path splitting there.
