2012-02-15Make -Wformat fix-its preserve original conversion specifiers.Hans Wennborg
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". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150578 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-15If a static data member of a class template which could be used in a constantRichard Smith
expression is referenced, defined, then referenced again, make sure we instantiate it the second time it's referenced. This is the static data member analogue of r150518. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150560 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-15Implement DR1454. This allows all intermediate results in constant expressionsRichard Smith
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150557 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-15Split reinterpret_casts of member pointers out from CK_BitCast; thisJohn McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150551 91177308-0d34-0410-b5e6-96231b3b80d8

(In response of Ted's review of r150112.) This moves the logic which checked if a symbol escapes through a parameter to invalidateRegionCallback (instead of post CallExpr visit.)

2012-02-14Use several weighted factors to determine typo candidate viablity.Kaelyn Uhrain
Replace the simple Levenshtein edit distance for typo correction candidates--and the hacky way adding namespace qualifiers would affect the edit distance--with a synthetic "edit distance" comprised of several factors and their relative weights. This also allows the typo correction callback object to convey more information about the viability of a correction candidate than simply viable or not viable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150495 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-14Fix another issue introduced by the proposed wording for core issue 1358: sinceRichard Smith
the instantiation of a constexpr function temploid is now always constexpr, a defaulted constexpr function temploid is often ill-formed by the rule in [dcl.fct.def.default]p2 that an explicitly-defaulted constexpr function must have a constexpr implicit definition.
