2012-07-02Reduce default template instantiation depth to 512; we're blowing outDouglas Gregor

2012-07-02Add a new libclang completion API to get brief documentation comment that isDmitri Gribenko
attached to a declaration in the completion string. Since extracting comments isn't free, a new code completion option is introduced. A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option. But because ASTUnit caches global declarations during parsing before even completion consumer is created, the option is duplicated as a translation unit option (in both libclang and ASTUnit, like the option to cache code completion results). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159539 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-26Add template type diffing to Clang. This feature will provide a betterRichard Trieu
comparison between two templated types when they both appear in a diagnostic. Type elision will remove indentical template arguments, which can be disabled with -fno-elide-type. Cyan highlighting is applied to the differing types. For more formatting, -fdiagnostic-show-template-tree will output the template type as an indented text tree, with differences appearing inline. Template tree works with or without type elision. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159216 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Restructure how the driver communicates information about theJohn McCall
target Objective-C runtime down to the frontend: break this down into a single target runtime kind and version, and compute all the relevant information from that. This makes it relatively painless to add support for new runtimes to the compiler. Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z, available at the driver level as a better and more general alternative to -fgnu-runtime and -fnext-runtime. This new concept of an Objective-C runtime also encompasses what we were previously separating out as the "Objective-C ABI", so fragile vs. non-fragile runtimes are now really modelled as different kinds of runtime, paving the way for better overall differentiation. As a sort of special case, continue to accept the -cc1 flag -fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak. I won't go so far as to say "no functionality change", even ignoring the new driver flag, but subtle changes in driver semantics are almost certainly not intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158793 91177308-0d34-0410-b5e6-96231b3b80d8

option. On the driver, check if we are using libraries from gcc 4.7 or newer and if so pass -fuse-init-array to the frontend. The crtbegin*.o files in gcc 4.7 no longer call the constructors listed in .ctors, so we have to use .init_array. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158694 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-13More doxygen/documentation cleanups.James Dennett
This reduces the number of warnings generated by Doxygen by about 100 (roughly 10%). Issues addressed: (1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments when they're not supposed to be Doxygen commands or links, and similarly for "<baz>" when it's not intended as as HTML tag; (2) Changed some \t commands (which don't exist) to \c ("to refer to a word of code", as the Doxygen manual says); (3) \precondition becomes \pre; (4) When touching comments, deleted a couple of spurious spaces in them; (5) Changed some \n and \r to \\n and \\r; (6) Fixed one tiny typo: #pragms -> #pragma. This patch touches documentation/comments only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158422 91177308-0d34-0410-b5e6-96231b3b80d8

http://llvm.org/bugs/show_bug.cgi?id=12924 This issue was that the source location was pointing to a non-printable character and so CaretEnd was pointing one _column_ past the caret but not one _character_ past the caret.

from the frontend when the location is invalid and the SourceManager null. Instead of keeping the SourceManager object in DiagnosticRenderer, propagate it to the calls accordingly (as reference when it is expected to not be null, or pointer when it may be null).
