2011-12-19Optimize serialized representation of redeclarable declarations forDouglas Gregor
which there are no redeclarations. This reduced by size of the PCH file for Cocoa.h by ~650k: ~536k of that was in the new LOCAL_REDECLARATIONS table, which went from a ridiculous 540k down to an acceptable 3.5k, while the rest was due to the more compact abbreviated representation of redeclarable declaration kinds (which no longer need to store the 'first' declaration ID). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146869 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-19constexpr handling improvements. Produce detailed diagnostics when a 'constexpr'Richard Smith
variable is initialized by a non-constant expression, and pass in the variable being declared so that earlier-initialized fields' values can be used. Rearrange VarDecl init evaluation to make this possible, and in so doing fix a long-standing issue in our C++ constant expression handling, where we would mishandle cases like: extern const int a; const int n = a; const int a = 5; int arr[n]; Here, n is not initialized by a constant expression, so can't be used in an ICE, even though the initialization expression would be an ICE if it appeared later in the TU. This requires computing whether the initializer is an ICE eagerly, and saving that information in PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146856 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-17Completely re-implement (de-)serialization of declarationDouglas Gregor
chains. The previous implementation relied heavily on the declaration chain being stored as a (circular) linked list on disk, as it is in memory. However, when deserializing from multiple modules, the different chains could get mixed up, leading to broken declaration chains. The new solution keeps track of the first and last declarations in the chain for each module file. When we load a declaration, we search all of the module files for redeclarations of that declaration, then splice together all of the lists into a coherent whole (along with any redeclarations that were actually parsed). As a drive-by fix, (de-)serialize the redeclaration chains of TypedefNameDecls, which had somehow gotten missed previously. Add a test of this serialization. This new scheme creates a redeclaration table that is fairly large in the PCH file (on the order of 400k for Cocoa.h's 12MB PCH file). The table is mmap'd in and searched via a binary search, but it's still quite large. A future tweak will eliminate entries for declarations that have no redeclarations anywhere, and should drastically reduce the size of this table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146841 91177308-0d34-0410-b5e6-96231b3b80d8
2011-12-17Split the Windows toolchain definition into its own file. This isChandler Carruth
especially nice as the Windows toolchain needs the windows header files, and has lots of platform specific hooks in it. To facilitate the split, hoist a bunch of file-level static helpers into class-level static helpers. Spiff up their doxygen comments while there as they're now more likely to be looked up via docs. Hopefully, this will be followed by further breaking apart of the toolchain definitions. Most of the large and complex ones should likely live on their own.

2011-12-17In Parser::SkipUntil do not stop at '@' unconditionally.Argyrios Kyrtzidis
Stopping at '@' was originally intended to avoid skipping an '@' at the @interface context when doing parser recovery, but we should not stop at all '@' tokens because they may be part of expressions (e.g. in @"string", @selector(), etc.), so in most cases we will want to skip them. This commit caused 'test/Parser/method-def-in-class.m' to fail for the cases where we tried to recover from unmatched angle bracket but IMO it is not a big deal to not have good recovery from such broken code and the way we did recovery would not always work anyway (e.g. if there was '@' in an expression). The case that rdar://7029784 is about still passes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@146815 91177308-0d34-0410-b5e6-96231b3b80d8
