2012-01-18constexpr: converted constant expression handling for enumerator values, caseRichard Smith
values and non-type template arguments of integral and enumeration types. This change causes some legal C++98 code to no longer compile in C++11 mode, by enforcing the C++11 rule that narrowing integral conversions are not permitted in the final implicit conversion sequence for the above cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148439 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18Convert SemaDecl.cpp to pass callback objects to CorrectTypo.Kaelyn Uhrain
Includes tests highlighting the cases where accuracy has improved (there is one call that does no filtering beyond selecting the set of allowed keywords, and one call that only triggers for ObjC code for which a test by someone who knows ObjC would be welcome). Also fixes a small typo in one of the suggestion messages, and drops a malformed "expected-note" for a suggestion that did not occur even when the malformed note was committed as r145930. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148420 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-18Optimize unqualified/global name lookup in modules by introducing aDouglas Gregor
generational scheme for identifiers that avoids searching the hash tables of a given module more than once for a given identifier. Previously, loading any new module invalidated all of the previous lookup results for all identifiers, causing us to perform the lookups repeatedly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148412 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18Improves support for Unicode in character literalsSeth Cantrell
Updates ProcessUCNExcape() for C++. C++11 allows UCNs in character and string literals that represent control characters and basic source characters. Also C++03 allows UCNs that refer to surrogate codepoints. UTF-8 sequences in character literals are now handled as single c-chars. Added error for multiple characters in Unicode character literals. Added errors for when a the execution charset encoding of a c-char cannot be represented as a single code unit in the associated character type. Note that for the purposes of this error the asso- ciated character type for a narrow character literal is char, not int, even though in C narrow character literals have type int. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148389 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-18Convert DiagnoseEmptyLookup to use correction callbacks.Kaelyn Uhrain
No new unit tests yet as there is no behavioral change (except for slightly more specific filtering in Sema::ActOnStartOfLambdaDefinition). Tests will be added as the code paths are traced in greater depth to determine how to improve the results--there are at least one or two known bugs that require those improvements. This commit lays the groundwork for those changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148382 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-18Move narrowing conversion detection code from SemaInit to SemaOverload, readyRichard Smith
for it to be used in converted constant expression checking, and fix a couple of issues: - Conversion operators implicitly invoked prior to the narrowing conversion were not being correctly handled when determining whether a constant value was narrowed. - For conversions from floating-point to integral types, the diagnostic text incorrectly always claimed that the source expression was not a constant expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148381 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-17Rename the first of 11 DeduceTemplateArguments overloads.Sebastian Redl
There are 5 functions of this name in Sema, and 6 more static helpers in SemaTemplateDeduction.cpp. The Sema functions have jobs like "deduce for function call", "deduce for taking the address", etc. The static helpers have jobs like "deduce by comparing two types", "deduce by comparing two lists of types", "deduce by comparing two template arguments", etc. The fact that they all are called the same and only differ in two of their 6 or more arguments makes the code using them very hard to read. Here I rename the one function that concerns me most at the moment, but as a matter of cleanup, the others will eventually be renamed as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148351 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-17Rework the way in which we (de-)serialize the declarationsDouglas Gregor
corresponding to TagType and ObjCInterfaceType. Previously, we would serialize the definition (if available) or the canonical declaration (if no definition was available). However, this can end up forcing the deserialization of the definition even through we might not want to yet. Instead, always serialize the canonical declaration reference in the TagType/ObjCInterfaceType entry, and as part of loading a pending definition, update the "decl" pointer within the type node to point at the definition. This is more robust in hard-to-isolate cases where the *Type gets built and filled in before we see the definition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@148323 91177308-0d34-0410-b5e6-96231b3b80d8
