2011-10-24Switch to a more natural formatting of the macro name printing.Chandler Carruth
Suggested by John McCall. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142836 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-16Hoist the logic I added to compute the macro name into a helperChandler Carruth
function. No functionality changed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142128 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-16Now that macro expansion notes are real notes and go through the sameChandler Carruth
formatting as any other diagnostic, they will be properly line wrapped and otherwise pretty printed. Let's take advantage of that and the new factoring to add some helpful information to them (much like template backtrace notes and other notes): the name of the macro whose expansion is being noted. This makes a world of difference if caret diagnostics are disabled, making the expansion notes actually useful in this case. It also helps ensure that in edge cases the information the user needs is present. Consider: % nl -ba t5.cc 1 #define M(x, y, z) \ 2 y 3 4 M( 5 1, 6 2, 7 3); We now produce: % ./bin/clang -fsyntax-only t5.cc t5.cc:6:3: error: expected unqualified-id 2, ^ t5.cc:2:3: note: expanded from macro: M y ^ 1 error generated. Without the added information in the note, the name of the macro being expanded would never be shown. This also deletes a FIXME to use the diagnostic formatting. It's not yet clear to me that we *can* do this reasonably, and the production of this message was my primary goal here anyways. I'd love any comments or suggestions on improving these notes, their wording, etc. Currently, I need to make them provide more helpful information in the presence of a token-pasting buffer, and I'm pondering adding something along the lines of "expanded from argument N of macro: ...". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142127 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-16Fix the original bug in our diagnostic printing that got me started onChandler Carruth
this long quest: actually use the note printing machinery for each macro expansion note rather than a hacky version of it. This will colorize and format the notes the same as any other. There is still some stuff to fix here, but it's one step closer. No test case changes because currently we don't do anything differently that I can FileCheck for -- I don't really want to try matching the color escape codes... Suggestions for how to test this are welcome. =] git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142121 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-16Now that the structure of this is more reasonably laid out, fix a longChandler Carruth
standing deficiency: we were providing no macro backtrace information whenever caret diagnostics were turned off. This sinks the logic for suppressing the code snippet and caret to the code that actually prints tho code snippet and caret. Along the way, clean up the naming of functions, remove some now fixed FIXMEs, and generally improve the wording and logic of this process. Add a test case exerecising this functionality. It is notable that the resulting messages are extremely low quality. I'm working on a follow-up patch that should address this and have left a FIXME in the test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142120 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-16Add proper doxyments to the entry point routine, and remove a dead parameter.Chandler Carruth
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142109 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-16Persist the TextDiagnostic object across multiple diagnostics as long asChandler Carruth
the SourceManager doesn't change, and the source files don't change. This greatly simplifies the interfaces and interactions. The lifetime of the TextDiagnostic object forms the 'session' over which we attempt to condense and deduplicate information in diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142104 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-15Clean up the names of all the TextDiagnostic methods (and even a staticChandler Carruth
function) to agree with the coding conventions, and in one case have a bit more information in it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142088 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-15Move two functions out of the public interface that shouldn't have everChandler Carruth
been there. Also delete their redundant doxyments in favor of those in the source file. I'm putting the doxyments for private and static helpers into the implementation file, and only the public interface doxyments into the header. If folks have strong opinions about this type of split, feel free to chime in, I'm happy to re-organize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142087 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-15Graduate the TextDiagnostic interface to its own header and source file,Chandler Carruth
making it accessible to anyone from the Frontend library. Still a good bit of cleanup to do here, but its a good milestone. This ensures that *all* of the functionality needed to implement the DiagnosticConsumer is exposed via the generic interface in some form. No sneaky re-use of static functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142086 91177308-0d34-0410-b5e6-96231b3b80d8
