2011-09-17Rename LangOptions::Microsoft to LangOptions::MicrosoftExt to make it clear ↵Francois Pichet
that this flag must be used only for Microsoft extensions and not emulation; to avoid confusion with the new LangOptions::MicrosoftMode flag.

2011-09-13For modules, use a hash of the compiler version, language options, andDouglas Gregor
target triple to separate modules built under different conditions. The hash is used to create a subdirectory in the module cache path where other invocations of the compiler (with the same version, language options, etc.) can find the precompiled modules. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139662 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-13When building a module on-demand, clear out the "non-modular" languageDouglas Gregor

2011-09-13Switch LangOptions over to a .def file that describes header of theDouglas Gregor
language options. Use that .def file to declare the LangOptions class and initialize all of its members, eliminating a source of annoying initialization bugs. AST serialization changes are next up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139605 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-12When an import statement fails to find a module in the module cache,Douglas Gregor
but there is a corresponding umbrella header in a framework, build the module on-the-fly so it can be immediately loaded at the import statement.

2011-09-01Allow the preprocessor to be constructed without performing target-Douglas Gregor
and language-specific initialization. Use this to allow ASTUnit to create a preprocessor object *before* loading the AST file. No actual functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138983 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-01Modules hide macro definitions by default, so that silly things likeDouglas Gregor
include guards don't show up as macro definitions in every translation unit that imports a module. Macro definitions can, however, be exported with the intentionally-ugly #__export_macro__ directive. Implement this feature by not even bothering to serialize non-exported macros to a module, because clients of that module need not (should not) know that these macros even exist. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138943 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-23Amend r138129 (reduction of SLocEntries) which introduced performance ↵Argyrios Kyrtzidis
regression due to increased calls to SourceManager::getFileID. (rdar://9992664) Use a slightly different approach that is more efficient both in terms of speed (no extra getFileID calls) and in SLocEntries reduction. Comparing pre-r138129 and this patch we get: For compiling SemaExpr.cpp reduction of SLocEntries by 26%. For the boost enum library: -SLocEntries -34% (note that this was -5% for r138129) -Memory consumption -50% -PCH size -31% Reduced SLocEntries also benefit the hot function SourceManager::getFileID, evident by the reduced "FileID scans". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138380 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-21Boost the efficiency of SourceManager::getMacroArgExpandedLocation.Argyrios Kyrtzidis
Currently getMacroArgExpandedLocation is very inefficient and for the case of a location pointing at the main file it will end up checking almost all of the SLocEntries. Make it faster: -Use a map of macro argument chunks to their expanded source location. The map is for a single source file, it's stored in the file's ContentCache and lazily computed, like the source lines cache. -In SLocEntry's FileInfo add an 'unsigned NumCreatedFIDs' field that keeps track of the number of FileIDs (files and macros) that were created during preprocessing of that particular file SLocEntry. This is useful when computing the macro argument map in skipping included files while scanning for macro arg FileIDs that lexed from a specific source file. Due to padding, the new field does not increase the size of SLocEntry. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138225 91177308-0d34-0410-b5e6-96231b3b80d8

functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@138127 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-18Implement '-Weverything', which enables all warnings except those explicitly ↵Ted Kremenek
mapped to be ignored. Currently this includes -pedantic warnings as well; we'll need to consider whether these should be included. This works as expected with -Werror. Test cases were added to Sema/warn-unused-parameters.c, but they should probably be broken off into their own test file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137910 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-17Introduce SourceManager::getMacroArgExpandedLocation function.Argyrios Kyrtzidis
If we pass it a source location that points inside a function macro argument, the returned location will be the macro location in which the argument was expanded. If a macro argument is used multiple times, the expanded location will be at the first expansion of the argument. e.g. MY_MACRO(foo); ^ Passing a file location pointing at 'foo', will yield a macro location where 'foo' was expanded into. Make SourceManager::getLocation call getMacroArgExpandedLocation as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137794 91177308-0d34-0410-b5e6-96231b3b80d8
