2013-01-25Rename the -cc1 option "-generate-module-index" toDouglas Gregor
"-fmodules-global-index" and expand its behavior to include both the use and generation of the global module index. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173404 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-24[analyzer] Replace "-analyzer-ipa" with "-analyzer-config ipa".Anna Zaks
The idea is to eventually place all analyzer options under "analyzer-config". In addition, this lays the ground for introduction of a high-level analyzer mode option, which will influence the default setting for IPAMode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173385 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

2013-01-23Add a new LangOpt NativeHalfType. This option allows for native half/fp16Joey Gouly
operations (as opposed to storage only half/fp16). Also add some semantic checks for OpenCL half types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173254 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-23Documentation cleanup: fixing documentation for FrontendAction.James Dennett
* Fix a typo, s/BeginSourceAction/BeginSourceFile/, so that the documentation for FrontendAction::BeginSourceFileAction links correctly to BeginSourceFile; * Add some basic \file documentation for FrontendAction.h; * More use of "\brief" instead of repeating the name of the entity being documented; * Stop using Doxygen-style "///" comments in FrontendAction.cpp, as they were polluting the documentation for BeginSourceFile; * Drop incorrect "\see" markup that broke Doxygen's formatting; * Other minor documentation fixes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173213 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-20Nuke SetUpBuildDumpLog.Sean Silva
Also, it was the only reason that `argc` and `argv` were being passed into createDiagnostics, so remove those parameters and clean up callers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172945 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-20Fix what appears to be a copy-paste error.Sean Silva
This looks like it was copied from SetUpBuildDumpLog, which dumps to the file `DiagOpts->DumpBuildInformation`. There is another member `DiagOpts->DiagnosticLogFile` which appears to be unused. The fact that this feature doesn't even print to the output file specified on the command line makes me think that it should be ripped out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@172944 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-15[driver] Warnings for warning options are handled by the frontend. The ↵Chad Rosier

2013-01-12Provide Decl::getOwningModule(), which determines the (sub)module inDouglas Gregor

2012-12-13More hacking on mapDiagnosticRanges to make it handle more cases.Eli Friedman
This still isn't quite right, but it fixes a crash. I factored out findCommonParent because we need it on the result of getImmediateExpansionRange: for a function macro, the beginning and end of an expansion range can come out of different macros/macro arguments, which means the resulting range is a complete mess to handle consistently. I also made some changes to how findCommonParent works; it works somewhat better in some cases, and somewhat worse in others, but I think overall it's a better balance. I'm coming to the conclusion that mapDiagnosticRanges isn't using the right algorithm, though: chasing the caret is fundamentally more complicated than any algorithm which only considers one FileID for the caret can handle because each SourceLocation doesn't really have a single parent. We need to follow the same path of choosing expansion locations and spelling locations which the caret used to come up with the correct range in the general case. Fixes <rdar://problem/12847524>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170049 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-11Extend stat query APIs to explicitly specify if the query is forArgyrios Kyrtzidis
a file or directory, allowing just a stat call if a file descriptor is not needed. Doing just 'stat' is faster than 'open/fstat/close'. This has the effect of cutting down system time for validating the input files of a PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169831 91177308-0d34-0410-b5e6-96231b3b80d8
