git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173408 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-25Implement the reader of the global module index and wire it into theDouglas Gregor
AST reader. The global module index tracks all of the identifiers known to a set of module files. Lookup of those identifiers looks first in the global module index, which returns the set of module files in which that identifier can be found. The AST reader only needs to look into those module files and any module files not known to the global index (e.g., because they were (re)built after the global index), reducing the number of on-disk hash tables to visit. For an example source I'm looking at, we go from 237844 total identifier lookups into on-disk hash tables down to 126817. Unfortunately, this does not translate into a performance advantage. At best, it's a wash once the global module index has been built, but that's ignore the cost of building the global module index (which is itself fairly large). Profiles show that the global module index code is far less efficient than it should be; optimizing it might give enough of an advantage to justify its continued inclusion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173405 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-23Fix for case-sensitive file systems. UghDouglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173303 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Implement the writer side of the global module index. Douglas Gregor
The global module index is a "global" index for all of the module files within a particular subdirectory in the module cache, which keeps track of all of the "interesting" identifiers and selectors known in each of the module files. One can perform a fast lookup in the index to determine which module files will have more information about entities with a particular name/selector. This information can help eliminate redundant lookups into module files (a serious performance problem) and help with creating auto-import/auto-include Fix-Its. The global module index is created or updated at the end of a translation unit that has triggered a (re)build of a module by scraping all of the .pcm files out of the module cache subdirectory, so it catches everything. As with module rebuilds, we use the file system's atomicity to synchronize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173301 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Factor the trait for lookup into the on-based hash table ofDouglas Gregor
identifiers into two parts: the part that involves dealing with the key (which can be re-used) and the ASTReader-specific part that creates the IdentifierInfos. While I'm at it, StringRef'ify this code, which was using pair<const char*, unsigned>. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173283 91177308-0d34-0410-b5e6-96231b3b80d8

forming the identifier, e.g., as part of a selector or a declaration name, don't actually deserialize any information about the identifier. Instead, simply mark it "out-of-date" and we'll load the the information on demand. 2% speedup on the modules testcase I'm looking at; should also help PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173056 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-21Introduce a fast path for the ASTReader's name lookup within aDouglas Gregor

2013-01-16Rework the traversal of Objective-C categories and extensions toDouglas Gregor
consider (sub)module visibility. The bulk of this change replaces myriad hand-rolled loops over the linked list of Objective-C categories/extensions attached to an interface declaration with loops using one of the four new category iterator kinds: visible_categories_iterator: Iterates over all visible categories and extensions, hiding any that have their "hidden" bit set. This is by far the most commonly used iterator. known_categories_iterator: Iterates over all categories and extensions, ignoring the "hidden" bit. This tends to be used for redeclaration-like traversals. visible_extensions_iterator: Iterates over all visible extensions, hiding any that have their "hidden" bit set. known_extensions_iterator: Iterates over all extensions, whether they are visible to normal name lookup or not. The effect of this change is that any uses of the visible_ iterators will respect module-import visibility. See the new tests for examples. Note that the old accessors for categories and extensions are gone; there are *Raw() forms for some of them, for those (few) areas of the compiler that have to manipulate the linked list of categories directly. This is generally discouraged. Part two of <rdar://problem/10634711>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172665 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-16[PCH/Modules] Change how macro [re]definitions are de/serialized.Argyrios Kyrtzidis
Previously we would serialize the macro redefinitions as a list, part of the identifier, and try to chain them together across modules individually without having the info that they were already chained at definition time. Change this by serializing the macro redefinition chain and then try to synthesize the chain parts across modules. This allows us to correctly pinpoint when 2 different definitions are ambiguous because they came from unrelated modules. Fixes bogus "ambiguous expansion of macro" warning when a macro in a PCH is redefined without undef'ing it first. rdar://13016031 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172620 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-14Implement parsing, AST, (de-)serialization, and placeholder globalDouglas Gregor
metadata for linking against the libraries/frameworks for imported modules. The module map language is extended with a new "link" directive that specifies what library or framework to link against when a module is imported, e.g., link "clangAST" or link framework "MyFramework" Importing the corresponding module (or any of its submodules) will eventually link against the named library/framework. For now, I've added some placeholder global metadata that encodes the imported libraries/frameworks, so that we can test that this information gets through to the IR. The format of the data is still under discussion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172437 91177308-0d34-0410-b5e6-96231b3b80d8
