2009-02-17fix a minor bug with my previous patchChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64747 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-17fix notes so that they are always filtered with the same logic Chris Lattner
as the last non-note diagnostic that preceeded them. This ensures that diagnostics in main files which have notes with locations in system headers get all the bits and pieces emitted or not in a unit. This fixes PR3215. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64746 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-15add a new SourceManager::getInstantiationRange helper method.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64606 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-15track "just a little more" location information for macro instantiations.Chris Lattner
Now instead of just tracking the expansion history, also track the full range of the macro that got replaced. For object-like macros, this doesn't change anything. For _Pragma and function-like macros, this means we track the locations of the ')'. This is required for PR3579 because apparently GCC uses the line of the ')' of a function-like macro as the location to expand __LINE__ to. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64601 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-13Give TargetInfo a new IntPtrType to hold the intptr_t type forChris Lattner
a target. Make Preprocessor.cpp define a new __INTPTR_TYPE__ macro based on this. On linux/32, set intptr_t to int, instead of long. This fixes PR3563. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64495 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-12FileManager:Ted Kremenek
- set the 'StatSysCallCache' object using a setter method instead of FileManager's constructor. This allows the cache to be installed after the FileManager object is created. - Add 'file mode' to FileEntry (useful for stat caching) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64351 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-12Add lightweight shim "clang::StatSysCallCache" that caches 'stat' system callsTed Kremenek
for use by FileManager. FileManager now takes a StatSysCallCache* in its constructor (which defaults to NULL). This will be used for evaluating whether or not caching 'stat' system calls in PTH is a performance win. This shim adds no observable performance impact in the case where the 'StatSysCallCache*' is null. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64345 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-04Some name-lookup-related fixes, from Piotr Rak!Douglas Gregor
- Changes Lookup*Name functions to return NamedDecls, instead of Decls. Unfortunately my recent statement that it will simplify lot of code, was not quite right, but it simplifies some... - Makes MergeLookupResult SmallPtrSet instead of vector, following Douglas suggestions. - Adds %qN format for printing qualified names to Diagnostic. - Avoids searching for using-directives in Scopes, which are not DeclScope, during unqualified name lookup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63739 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04Implement handling of file entry/exit notifications from GNUChris Lattner

2009-02-04add the difference in the line marker phys line number and theChris Lattner
query point to the returned presumed location. We now produce: foo.h:92:2: warning: #warning blarg! #warning blarg! ^ foo.h:93:2: warning: #warning blarg! #warning blarg! ^ foo.h:94:2: warning: #warning blarg! #warning blarg! ^ for: #line 92 "foo.h" #warning blarg! #warning blarg! #warning blarg! blarg indeed! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63710 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04add really really trivial #line support, where #line now makes every Chris Lattner
location below it report as coming from the #line location. For example, with: #line 92 "foo.h" #warning blarg! #warning blarg! we now emit: foo.h:92:2: warning: #warning blarg! #warning blarg! ^ foo.h:92:2: warning: #warning blarg! #warning blarg! ^ git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63709 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04lower the interface to getLineNumber like we did forChris Lattner
getColumnNumber. This fixes a FIXME in SourceManager::getPresumedLoc because we now just decompose the sloc once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63701 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-04make SM::getColumnNumber take a predecomposed FileID/offset, whichChris Lattner
makes it clear to clients that they have to pick an instantiation or spelling location before calling it and allows optimization based on that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63698 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-03reclaim my precious bit in FileInfo by ensuring that ContentCache objectsChris Lattner
are 8-byte aligned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63630 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03switch SourceManager from using an std::map and std::list of Chris Lattner
ContentCache objects to using a densemap and list, and allocating the ContentCache objects from a bump pointer. This does not speed up or slow down things substantially, but gives us control over their alignment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63628 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-27Split the single monolithic DiagnosticKinds.def file into oneChris Lattner
.def file for each library. This means that adding a diagnostic to sema doesn't require all the other libraries to be rebuilt. Patch by Anders Johnsen! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63111 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-27Introduce a new PresumedLoc class to represent the concept of a locationChris Lattner
as reported to the user and as manipulated by #line. This is what __FILE__, __INCLUDE_LEVEL__, diagnostics and other things should follow (but not dependency generation!). This patch also includes several cleanups along the way: - SourceLocation now has a dump method, and several other places that did similar things now use it. - I cleaned up some code in AnalysisConsumer, but it should probably be simplified further now that NamedDecl is better. - TextDiagnosticPrinter is now simplified and cleaned up a bit. This patch is a prerequisite for #line, but does not actually provide any #line functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63098 91177308-0d34-0410-b5e6-96231b3b80d8
