2009-03-04Add an optional "tag" to conjured symbols that allows us to distinguish betweenTed Kremenek
multiple symbols conjured at the same location. All that is required of the tag is that it is a fixed void* value that points to an memory address that remains valid throughout the remainder of the lifetime of the SymbolManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66092 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Partial fix for <rdar://problem/6645157> [clang on Xcode; regression]: ↵Steve Naroff
error: instance variable 'someField' is private. A recent regression caused by http://llvm.org/viewvc/llvm-project?rev=65912&view=rev. This commit isn't fully baked. Nevertheless, it should cause Xcode to compile again. Will speak with Fariborz offline. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66045 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Finish up some fixes related to <rdar://problem/6497631> Message lookup is ↵Steve Naroff
sometimes different than gcc's. - Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch). - Tighten up lookup when messaging 'self'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66033 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Add __block codegen testcase. We introduce a temporary flag to enableMike Stump
codegen, until such time as codegen is complete enough to turn on with -fblocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66031 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Driver: More Option implementation.Daniel Dunbar
- Add Options.def file, collects option information. - Actual option instantiation is handled lazily by OptTable to allow the driver to not need to instantiate all options. - cast<> support for Option, other minor tweaks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66028 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04make the token lexer allocate its temporary token buffers forChris Lattner
preexpanded macro arguments from the preprocessor's bump pointer. This reduces # mallocs from 12444 to 11792. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66025 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Switch attributes to be allocated from the declcontext bump pointer just likeChris Lattner
decls. This reduces the number of calls to malloc on cocoa.h with pth and -disable-free from 15958 to 12444 times (down ~3500). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66023 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04add an a Attr::Destroy method and force clients to go through it. As part of Chris Lattner
this, make DeclBase::Destroy destroy attributes instead of the DeclBase dtor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66020 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Minor cleanup for choose expressions: add a helper that returns the Eli Friedman
chosen sub-expression, rather than just evaluating the condition. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66018 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04allocate MultiKeywordSelector's out of a bump pointer allocator instead of ↵Chris Lattner
malloc. This has two advantages 1) no more leaking them, 2) fewer calls to malloc. This changes us from calling malloc 3685/1390/883/2974/1185 times respectively on 16/20/24/28/32 byte objects when parsing cocoa.h with pth and -disable-free to calling it 2816/1020/702/2903/1168 times each respectively. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66017 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04simplify Sema::AddInstanceMethodToGlobalPool, no functionality change.Chris Lattner

2009-03-04add a special case for codegen that improves the case where we haveChris Lattner
multiple sequential cases to a) not create tons of fall-through basic blocks and b) not recurse deeply. This fixes codegen on 100K deep cases, and improves codegen on moderate cases from this: switch i32 %tmp, label %sw.epilog [ i32 1000, label %sw.bb i32 1001, label %sw.bb1 i32 1002, label %sw.bb2 i32 1003, label %sw.bb3 i32 1004, label %sw.bb4 ... sw.bb: ; preds = %entry br label %sw.bb1 sw.bb1: ; preds = %entry, %sw.bb br label %sw.bb2 sw.bb2: ; preds = %entry, %sw.bb1 br label %sw.bb3 sw.bb3: ; preds = %entry, %sw.bb2 br label %sw.bb4 to: switch i32 %tmp, label %sw.epilog [ i32 1000, label %sw.bb i32 1001, label %sw.bb i32 1002, label %sw.bb i32 1003, label %sw.bb i32 1004, label %sw.bb sw.bb: ;; many preds git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66015 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Continuation of PR3687: fix more places to use the right type for Eli Friedman
booleans. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66012 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Change Parser::ParseCaseStatement to use an iterative approach to parsingChris Lattner
multiple sequential case statements instead of doing it with recursion. This fixes a problem where we run out of stack space parsing 100K directly nested cases. There are a couple other problems that prevent this from being useful in practice (right now the example only parses correctly with -disable-free and doesn't work with -emit-llvm), but this is a start. I'm not including a testcase because it is large and uninteresting for regtesting. Sebastian, I would appreciate it if you could scrutinize the smart pointer gymnastics I do. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66011 91177308-0d34-0410-b5e6-96231b3b80d8
