2012-02-07Revert my patches which removed Diagnostic.h includes by moving some ↵Benjamin Kramer
operator overloads out of line. This seems to negatively affect compile time onsome ObjC tests (which use a lot of partial diagnostics I assume). I have to come up with a way to keep them inline without including Diagnostic.h everywhere. Now adding a new diagnostic requires a full rebuild of e.g. the static analyzer which doesn't even use those diagnostics. This reverts commit 6496bd10dc3a6d5e3266348f08b6e35f8184bc99. This reverts commit 7af19b817ba964ac560b50c1ed6183235f699789. This reverts commit fdd15602a42bbe26185978ef1e17019f6d969aa7. This reverts commit 00bd44d5677783527d7517c1ffe45e4d75a0f56f.

2012-02-04Remove Diagnostic.h include from Preprocessor.h.Benjamin Kramer
- Move the offending methods out of line and fix transitive includers. - This required changing an enum in the PPCallback API into an unsigned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149782 91177308-0d34-0410-b5e6-96231b3b80d8

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. Many of the code now under LangOptions::MicrosoftExt will eventually be moved under the LangOptions::MicrosoftMode flag. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139987 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-28Rename tok::eom to tok::eod.Peter Collingbourne
The previous name was inaccurate as this token in fact appears at the end of every preprocessing directive, not just macro definitions. No functionality change, except for a diagnostic tweak. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126631 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-02Frontend: Factor out header include dumping (-H) into its own preprocessorDaniel Dunbar
callbacks class. - Aside from being generally cleaner, this also allows -H to work correctly in modes other than standard preprocessing (e.g., -c, -MM, etc.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124723 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-19Several PPCallbacks take an SourceLocation + IdentifierInfo, ratherCraig Silverstein
than a Token that holds the same information all in one easy-to-use package. There's no technical reason to prefer the former -- the information comes from a Token originally -- and it's clumsier to use, so I've changed the code to use tokens everywhere. Approved by clattner git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119845 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-12Make sure to always check the result ofDouglas Gregor
SourceManager::getPresumedLoc(), so that we don't try to make use of an invalid presumed location. Doing so can cause crashes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118885 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-09When we parse a pragma, keep track of how that pragma was originallyDouglas Gregor
spelled (#pragma, _Pragma, __pragma). In -E mode, use that information to add appropriate newlines when translating _Pragma and __pragma into #pragma, like GCC does. Fixes <rdar://problem/8412013>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113553 91177308-0d34-0410-b5e6-96231b3b80d8

#undefs in -dD mode. (PR7818) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110523 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-13Modify the pragma handlers to accept and use StringRefs instead of ↵Argyrios Kyrtzidis
IdentifierInfos. When loading the PCH, IdentifierInfos that are associated with pragmas cause declarations that use these identifiers to be deserialized (e.g. the "clang" pragma causes the "clang" namespace to be loaded). We can avoid this if we just use StringRefs for the pragmas. As a bonus, since we don't have to create and pass IdentifierInfos, the pragma interfaces get a bit more simplified. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108237 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-20push some source location information down through the compiler,Chris Lattner
into ContentCache::getBuffer. This allows it to produce diagnostics on the broken #include line instead of without a location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101939 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16Remove this hard-coded buffer size. In some basic experiments preprocessingDan Gohman
large files, this doesn't seem significantly better than just letting raw_ostream pick a buffer size. This code predates raw-ostream's automatic buffer sizing; in fact, it was introduced as part of the code which would eventually become raw_ostream. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101473 91177308-0d34-0410-b5e6-96231b3b80d8
