2011-03-18Add support for language-specific address spaces. On top of that,Peter Collingbourne
add support for the OpenCL __private, __local, __constant and __global address spaces, as well as the __read_only, _read_write and __write_only image access specifiers. Patch originally by ARM; language-specific address space support by myself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127915 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-16Having FileManager::getFile always open the file, brought much consternation ↵Argyrios Kyrtzidis
and leaking of file descriptors. Add 'openFile' bool to FileManager::getFile to specify whether we want to have the file opened or not, have it false by default, and enable it only in HeaderSearch.cpp where the open+fstat optimization matters.

2011-03-15Stop leaking file descriptors.Argyrios Kyrtzidis
After the open+fstat optimization, files were already opened for FileManager::getBufferForFile() and we closed them after reading them. The problem was that when -working-directory was passed, the code path that actually reuses & closes the already opened file descriptor was not followed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127639 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-05Currently we can only remap a file by creating a MemoryBuffer and replacing ↵Argyrios Kyrtzidis

2011-02-11Improves Clang's virtual file handling.Zhanyong Wan
This patch contains: - making some of the existing comments more accurate in the presence of virtual files/directories. - renaming some private data members of FileManager to match their roles better. - creating 'DirectorEntry's for the parent directories of virtual files, such that we can tell whether two virtual files are from the same directory. This is useful for injecting virtual files whose directories don't exist in the real file system. - minor clean-ups and adding comments for class FileManager::UniqueDirContainer and FileManager::UniqueFileContainer. - adding statistics on virtual files to FileManager::PrintStats(). - adding unit tests to verify the existing and new behavior of FileManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125384 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-10Implement two related optimizations that make de-serialization ofDouglas Gregor
AST/PCH files more lazy: - Don't preload all of the file source-location entries when reading the AST file. Instead, load them lazily, when needed. - Only look up header-search information (whether a header was already #import'd, how many times it's been included, etc.) when it's needed by the preprocessor, rather than pre-populating it. Previously, we would pre-load all of the file source-location entries, which also populated the header-search information structure. This was a relatively minor performance issue, since we would end up stat()'ing all of the headers stored within a AST/PCH file when the AST/PCH file was loaded. In the normal PCH use case, the stat()s were cached, so the cost--of preloading ~860 source-location entries in the Cocoa.h case---was relatively low. However, the recent optimization that replaced stat+open with open+fstat turned this into a major problem, since the preloading of source-location entries would now end up opening those files. Worse, those files wouldn't be closed until the file manager was destroyed, so just opening a Cocoa.h PCH file would hold on to ~860 file descriptors, and it was easy to blow through the process's limit on the number of open file descriptors. By eliminating the preloading of these files, we neither open nor stat the headers stored in the PCH/AST file until they're actually needed for something. Concretely, we went from *** HeaderSearch Stats: 835 files tracked. 364 #import/#pragma once files. 823 included exactly once. 6 max times a file is included. 3 #include/#include_next/#import. 0 #includes skipped due to the multi-include optimization. 1 framework lookups. 0 subframework lookups. *** Source Manager Stats: 835 files mapped, 3 mem buffers mapped. 37460 SLocEntry's allocated, 11215575B of Sloc address space used. 62 bytes of files mapped, 0 files with line #'s computed. with a trivial program that uses a chained PCH including a Cocoa PCH to *** HeaderSearch Stats: 4 files tracked. 1 #import/#pragma once files. 3 included exactly once. 2 max times a file is included. 3 #include/#include_next/#import. 0 #includes skipped due to the multi-include optimization. 1 framework lookups. 0 subframework lookups. *** Source Manager Stats: 3 files mapped, 3 mem buffers mapped. 37460 SLocEntry's allocated, 11215575B of Sloc address space used. 62 bytes of files mapped, 0 files with line #'s computed. for the same program. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125286 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-05Improve our uniquing of file entries when files are re-saved or areDouglas Gregor
overridden via remapping. Thus, when we create a "virtual" file in the file manager, we still stat() the real file that lives behind it so that we can provide proper uniquing based on inodes. This helps keep the file manager much more consistent. To take advantage of this when reparsing files in libclang, we disable the use of the stat() cache when reparsing or performing code completion, since the stat() cache is very likely to be out of date in this use case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124971 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-03Teach SourceManager::getLocation() how to cope with a source fileDouglas Gregor
whose inode has changed since the file was first created and that is being seen through a different path name (e.g., due to symlinks or relative path elements), such that its FileEntry pointer doesn't match a known FileEntry pointer. Since this requires a system call (to stat()), we only perform this deeper checking if we can't find the file by comparing FileEntry pointers. Also, add a micro-optimization where we don't bother to compute line numbers when given the location (1, 1). This improves the efficiency of clang_getLocationForOffset(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124800 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-02Canonicalize path names in the file manager before performing a lookupDouglas Gregor
on that name. Canonicalization eliminates silliness such as "." and "foo/.." that breaks the uniquing of files in the presence of virtual files or files whose inode numbers have changed during parsing/re-parsing. c-index-test isn't able to create this crazy situation, so I've resorted to testing outside of the Clang tree.
