2010-08-29Implement C++0x user-defined string literals.Sean Hunt
The extra data stored on user-defined literal Tokens is stored in extra allocated memory, which is managed by the PreprocessorLexer because there isn't a better place to put it that makes sure it gets deallocated, but only after it's used up. My testing has shown no significant slowdown as a result, but independent testing would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112458 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-26Introduce basic support for loading a precompiled preamble whileDouglas Gregor
reparsing an ASTUnit. When saving a preamble, create a buffer larger than the actual file we're working with but fill everything from the end of the preamble to the end of the file with spaces (so the lexer will quickly skip them). When we load the file, create a buffer of the same size, filling it with the file and then spaces. Then, instruct the lexer to start lexing after the preamble, therefore continuing the parse from the spot where the preamble left off. It's now possible to perform a simple preamble build + parse (+ reparse) with ASTUnit. However, one has to disable a bunch of checking in the PCH reader to do so. That part isn't committed; it will likely be handled with some other kind of flag (e.g., -fno-validate-pch). As part of this, fix some issues with null termination of the memory buffers created for the preamble; we were trying to explicitly NULL-terminate them, even though they were also getting implicitly NULL terminated, leading to excess warnings about NULL characters in source files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109445 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-22Improve performance during cursor traversal when a region of interestDouglas Gregor
is present. Rather than using clang_getCursorExtent(), which requires us to lex the token at the ending position to determine its length. Then, we'd be comparing [a, b) source ranges that cover the characters in the range rather than the normal behavior for Clang's source ranges, which covers the tokens in the range. However, relexing causes us to read the source file (which may come from a precompiled header), which is rather unfortunate and affects performance. In the new scheme, we only use Clang-style source ranges that cover the tokens in the range. At the entry points where this matters (clang_annotateTokens, clang_getCursor), we make sure to move source locations to the start of the token. Addresses most of <rdar://problem/8049381>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109134 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-20Introduce a new lexer function to compute the "preamble" of a file,Douglas Gregor
which is the part of the file that contains all of the initial comments, includes, and preprocessor directives that occur before any of the actual code. Added a new -print-preamble cc1 action that is only used for testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108913 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
