2009-03-07Remove last FIXME for block literal codegen that I know about and turnMike Stump
on all the new code by default. There is still plenty of testing to do and issues I'm sure need resolving. Let me know if you find anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66323 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-07Remove some FIXMEs for block literals that should be close to working.Mike Stump

2009-03-07Back out the patch in r66302, and re-fix it properly. We assume for Eli Friedman
performance that the type of the returned llvm::Value for an expression matches the converted type of the clang::Expr; mismatches will cause all sorts of errors and silent miscompilations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66321 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-05Don't mangle names of local variables.Daniel Dunbar
- For one thing, this adds unneeded overhead; for another, this routine can be used to emit unnamed decls which we shouldn't try to mangle. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66212 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-05Make IRGen compatible with declaring a function with incomplete Eli Friedman
return/argument types. (The generated IR isn't ideal, but we can't really do better in general.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66132 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Move more of blocks codegen out of CodeGenModule and into theMike Stump
BlockModule. No functionality change. This should help people that don't want to know anything about blocks not be confused by the overloaded use of the term block or nor want to see all the blocks goop. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66042 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
2009-03-04Minor 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
2009-03-04add 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.
