2011-02-19Warn about code that uses variables and functions with internal linkageJohn McCall
without defining them. This should be an error, but I'm paranoid about "uses" that end up not actually requiring a definition. I'll revisit later. Also, teach IR generation to not set internal linkage on variable declarations, just for safety's sake. Doing so produces an invalid module if the variable is not ultimately defined. Also, fix several places in the test suite where we were using internal functions without definitions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126016 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-18The flags we're supposed to write into a byref struct are *not* theJohn McCall
_Block_object_* flags; it's just BLOCK_HAS_COPY_DISPOSE or not. Also, we don't need to chase forwarding pointers prior to calling _Block_object_dispose; _Block_object_dispose in fact already does this. rdar://problem/9006315 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125823 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-18Move CompilerInstance::LLVMContext and LLVMContext ownership to CodeGenActionPeter Collingbourne
This removes the final dependency edge from any lib outside of CodeGen to core. As a result we can, and do, trim the dependency on core from libclang, PrintFunctionNames, the unit tests and c-index-test. While at it, review and trim other unneeded dependencies. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125820 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-18implement basic support for __label__. I wouldn't be shocked if there areChris Lattner
bugs from other clients that don't expect to see a LabelDecl in a DeclStmt, but if so they should be easy to fix. This implements most of PR3429 and rdar://8287027 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125817 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125761 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-17Change the representation of GNU ?: expressions to use a different expressionJohn McCall
class and to bind the shared value using OpaqueValueExpr. This fixes an unnoticed problem with deserialization of these expressions where the deserialized form would lose the vital pointer-equality trait; or rather, it fixes it because this patch also does the right thing for deserializing OVEs. Change OVEs to not be a "temporary object" in the sense that copy elision is permitted. This new representation is not totally unawkward to work with, but I think that's really part and parcel with the semantics we're modelling here. In particular, it's much easier to fix things like the copy elision bug and to make the CFG look right. I've tried to update the analyzer to deal with this in at least some obvious cases, and I think we get a much better CFG out, but the printing of OpaqueValueExprs probably needs some work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125744 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-17Step #1/N of implementing support for __label__: split labels intoChris Lattner
LabelDecl and LabelStmt. There is a 1-1 correspondence between the two, but this simplifies a bunch of code by itself. This is because labels are the only place where we previously had references to random other statements, causing grief for AST serialization and other stuff. This does cause one regression (attr(unused) doesn't silence unused label warnings) which I'll address next. This does fix some minor bugs: 1. "The only valid attribute " diagnostic was capitalized. 2. Various diagnostics printed as ''labelname'' instead of 'labelname' 3. This reduces duplication of label checking between functions and blocks. Review appreciated, particularly for the cindex and template bits. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125733 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-16Don't call objc_read_weak as part of emitting a block literal.John McCall
Nobody ever gave me a clear reason for why we were doing this, and now it's apparently causing serious problems, so if *not* having this causes problems, we get to solve them the right way this time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125627 91177308-0d34-0410-b5e6-96231b3b80d8

a zero constant for a complete class. rdar://problem/8424975 To make this happen, track the field indexes for virtual bases in the complete object.
