* Revert "Add a completed/incomplete type difference. This allows us to have"Eric Christopher2012-02-152-188/+66

* Add a completed/incomplete type difference. This allows us to haveEric Christopher2012-02-152-66/+188
| | | | | | | | | | | | | | | | partial types for contexts and forward decls while allowing us to complete types later on for debug purposes. This piggy-backs on the metadata replacement and rauw changes for temporary nodes and takes advantage of the incremental support I added in earlier. This allows us to, if we decide, to limit adding methods and variables to structures in order to limit the amount of debug information output into a .o file. The caching is a bit complicated though so any thoughts on untangling that are welcome. llvm-svn: 150631

* Improve typo correction involving nested name specifiers.Kaelyn Uhrain2012-02-151-18/+112
| | | | | | | | | | | | Snooping in other namespaces when the identifier being corrected is already qualified (i.e. a valid CXXScopeSpec is passed to CorrectTypo) and ranking synthesized namespace qualifiers relative to the existing qualifier is now performed. Support for disambiguating the string representation of synthesized namespace qualifers has also been added (the change to test/Parser/cxx-using-directive.cpp is an example of an ambiguous relative qualifier). llvm-svn: 150622

* Remove the unuseful -fdiagnostics-show-nameDavid Blaikie2012-02-154-115/+4
| | | | | | | | | | | | | | This option was added in r129614 and doesn't have any use case that I'm aware of. It's possible that external tools are using these names - and if that's the case we can certainly reassess the functionality, but for now it lets us shave out a few unneeded bits from clang. Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool. This removes the actual diagnostic name strings from clang entirely.

* Make -Wformat fix-its preserve original conversion specifiers.Hans Wennborg2012-02-153-14/+22
| | | | | | | | | | | | | | | | | This commit makes PrintfSpecifier::fixType() and ScanfSpecifier::fixType() only fix a conversion specification enough that Clang wouldn't warn about it, as opposed to always changing it to use the "canonical" conversion specifier. (PR11975) This preserves the user's choice of conversion specifier in cases like: printf("%a", (long double)1); where we previously suggested "%Lf", we now suggest "%La" printf("%x", (long)1); where we previously suggested "%ld", we now suggest "%lx". llvm-svn: 150578

* Implement DR1454. This allows all intermediate results in constant expressionsRichard Smith2012-02-152-166/+267
| | | | | | | | | | | | to be core constant expressions (including pointers and references to temporaries), and makes constexpr calculations Turing-complete. A Turing machine simulator is included as a testcase. This opens up the possibilty of removing CCValue entirely, and removing some copies from the constant evaluator in the process, but that cleanup is not part of this change. llvm-svn: 150557

* Split reinterpret_casts of member pointers out from CK_BitCast; thisJohn McCall2012-02-1512-44/+148
| | | | | | | | | | | | | | | | | | | | | is general goodness because representations of member pointers are not always equivalent across member pointer types on all ABIs (even though this isn't really standard-endorsed). Take advantage of the new information to teach IR-generation how to do these reinterprets in constant initializers. Make sure this works when intermingled with hierarchy conversions (although this is not part of our motivating use case). Doing this in the constant-evaluator would probably have been better, but that would require a *lot* of extra structure in the representation of constant member pointers: you'd really have to track an arbitrary chain of hierarchy conversions and reinterpretations in order to get this right. Ultimately, this seems less complex. I also wasn't quite sure how to extend the constant evaluator to handle foldings that we don't actually want to treat as extended constant expressions. llvm-svn: 150551
