"When dumping the tokens (-dumptokens output type), the column numbers are not correctly shown. This patch fixes that issue." git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53796 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-26clang uses the llvm backend, so define __llvm__ like llvm-gcc. Chris Lattner
Additionally, define __clang__ so clients can predicate based on clang features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52788 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-15Fix rewriter bug <rdar://problem/5929344> clang ObjC rewriter: "extern int ↵Steve Naroff
__CFConstantStringClassReference[];" should be extern "C". Have clang predefine OBJC_NEW_PROPERTIES (which is what gcc does). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51163 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-09DO NOT pre-defined __OBJC2__. The __OBJC2__ macro should only be defined ↵Steve Naroff
when targeting the new, Apple 2.0 *runtime ABI*. It is not intended to be used to #ifdef ObjC 2.0 langauge features. This is unfortunate (given it's name). In a perfect world, this defined would be named __OBJC2_RUNTIME_ABI__. Oh well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50913 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-05Neil pointed out that clang doesn't generate ranges from diagnosticsChris Lattner
related to pp-expressions. Doing so is pretty simple and this patch implements it, yielding nice diagnostics like: t.c:2:7: error: division by zero in preprocessor expression #if 1 / (0 + 0) ~ ^ ~~~~~~~ t.c:5:14: error: expected ')' in preprocessor expression #if (412 + 42 ~~~~~~~~^ t.c:5:5: error: to match this '(' #if (412 + 42 ^ t.c:10:10: warning: left side of operator converted from negative value to unsigned: -42 to 18446744073709551574 #if (-42 + 0U) / -2 ~~~ ^ ~~ t.c:10:16: warning: right side of operator converted from negative value to unsigned: -2 to 18446744073709551614 #if (-42 + 0U) / -2 ~~~~~~~~~~ ^ ~~ 5 diagnostics generated. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50638 91177308-0d34-0410-b5e6-96231b3b80d8

dstor. clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and passes it to the preprocessor object. clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main(). html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new Preprocessor to highlight macros. class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros(). Updated clients of HTMLDiagnostics to use this new interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49875 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-18move #include to the file that needs it.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48485 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
