2010-07-20Hide FunctionTemplateDecl's specializations folding set as implementation ↵Argyrios Kyrtzidis
detail and introduce FunctionTemplateDecl::findSpecialization. Redeclarations of specializations will not cause the previous decl to be removed from the set, the set will keep the canonical decl. findSpecialization will return the most recent redeclaration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108834 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Whether the specialization should be added to template's folding set when ↵Argyrios Kyrtzidis
read from PCH, is determined by a isCanonicalDecl check. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108833 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Update ImplicitCastExpr to be able to represent an XValue.Sebastian Redl

2010-07-19Remove PCHReader::getStream(), it was unused. Inline ↵Sebastian Redl
PCHReader::getDelsCursor() into its sole caller and remove it. This reduces the attack surface of multiple PCH files towards code outside the PCH implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108763 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-19Introduce a new libclang API, clang_reparseTranslationUnit(), whichDouglas Gregor
reparses an already-parsed translation unit. At the moment it's just a convenience function, but we hope to use it for performance optimizations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108756 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-19Promote the identifier table to per-file data. Also, if a CHAINED_METADATA ↵Sebastian Redl
record exists, it has to be the first thing in the PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108748 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-19Driver: Change the driver to take the path to the main executable, instead ofDaniel Dunbar
taking it in pieces. - Fixes a problem where the Clang executable path was not initialized properly on Win32, because sys::Path::getBasename() doesn't do what I always think it does. Imagine that, a sys::Path interface that is confusing! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108667 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-17Teach the PCH reader to load the dependency when encountering a chain ↵Sebastian Redl

2010-07-16Improved false positive rate for the idempotent operations checker and moved ↵Tom Care
it into the default path-sensitive analysis options. - Added checks for static local variables, self assigned parameters, and truncating/extending self assignments - Removed command line option (now default with --analyze) - Updated test cases to pass with idempotent operation warnings git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108550 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-16First baby steps towards PCHReader being able to keep track of multiple PCH ↵Sebastian Redl
files. WIP git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108537 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-14Add a callback interface that allows interested parties to get notified ↵Sebastian Redl
whenever PCHReader deserializes a type or decl (and possibly other things in the future). Have PCHWriter implement these callbacks as noops and register to receive them if we're chaining PCHs. This will allow PCHWriter to track the IDs of these things, which it needs to write the dependent files. WIP git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108383 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-14There is another implementation of PCHReaderListener around. Update it to ↵Sebastian Redl
the new interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108377 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-13Downgrade the "when type is in parentheses, array cannot have dynamicDouglas Gregor
size" error for code like new (int [size]) to a warning, add a Fix-It to remove the parentheses, and make this diagnostic work properly when it occurs in a template instantiation. <rdar://problem/8018245>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108242 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Modify the pragma handlers to accept and use StringRefs instead of ↵Argyrios Kyrtzidis
IdentifierInfos. When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded). We can avoid this if we just use StringRefs for the pragmas. As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108237 91177308-0d34-0410-b5e6-96231b3b80d8

implementation to the latter. WIP. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108200 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-09When given the -chained-pch option and a previous PCH file, have the ↵Sebastian Redl
PCHWriter emit a CHAINED_METADATA record instead of METADATA, and write a link to the previous file there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108014 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-09Introduce -f{no-}spell-checking options to enable/disableDouglas Gregor
spell-checking. By default, spell-checking is enabled for Clang (obviously) but disabled in CIndex for performance reasons. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107992 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-09Add a frontend option -chained-pch and don't pass an active PCH reader to ↵Sebastian Redl
the PCH writer if it is not set, preventing creation of chained PCH files. Since the reader is so far unused, effectively no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107936 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-08Introduce PCHReader::GetTranslationUnitDecl() and use it instead of ↵Argyrios Kyrtzidis
ReadDeclRecord when initializing. ReadDeclRecord would hit assertion if the translation unit declaration was already loaded during IdentifierInfo initialization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107885 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-08For TagType and TemplateSpecializationType, isDependent calculation may be ↵Argyrios Kyrtzidis
invalid because some decls that the calculation is using may still be initializing. Thus, store the isDependent flag to PCH and restore directly to Type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@107873 91177308-0d34-0410-b5e6-96231b3b80d8
