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
2008-05-08The awesome GNU "comma elision extension" works with both the standardChris Lattner
__VA_ARGS__ syntax as well as with the amazingly awesome GNU "named variadic macro" extension. Allow it with the GNU syntax as well. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50843 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

2008-05-04Fix the rest of PR2279:Chris Lattner
a) correct rejection of ',' in pp expressions. b) the precedence of ',' was wrong w.r.t. ?:. Thanks again to Neil for finding these and providing testcases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50625 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
