2009-02-28First cut CodeGen support for __block variables.Mike Stump
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65688 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-27Change the AST generated for offsetof a bit so that it looks like a Eli Friedman
normal expression, and change Evaluate and IRGen to evaluate it like a normal expression. This simplifies the code significantly, and fixes PR3396. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65622 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-24first wave of fixes for @encode sema support. This is part of PR3648.Chris Lattner
The big difference here is that (like string literal) @encode has array type, not pointer type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65391 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-12Initial codegen for block literals. This is a work in progress. I'veMike Stump

2009-01-29Make CodeGen produce an error if we come across a non-constant initializer ↵Douglas Gregor
list that involves the GNU array-range designator extension git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63327 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-29Introduce a new expression node, ImplicitValueInitExpr, thatDouglas Gregor
represents an implicit value-initialization of a subobject of a particular type. This replaces the (ab)use of CXXZeroValueInitExpr within initializer lists for the "holes" that occur due to the use of C99 designated initializers. The new test case is currently XFAIL'd, because CodeGen's ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be taught to value-initialize when it sees ImplicitValueInitExprs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63317 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-28Code generation support for C99 designated initializers.Douglas Gregor
The approach I've taken in this patch is relatively straightforward, although the code itself is non-trivial. Essentially, as we process an initializer list we build up a fully-explicit representation of the initializer list, where each of the subobject initializations occurs in order. Designators serve to "fill in" subobject initializations in a non-linear way. The fully-explicit representation makes initializer lists (both with and without designators) easy to grok for codegen and later semantic analyses. We keep the syntactic form of the initializer list linked into the AST for those clients interested in exactly what the user wrote. Known limitations: - Designating a member of a union that isn't the first member may result in bogus initialization (we warn about this) - GNU array-range designators are not supported (we warn about this) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63242 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-20Make VLAs usable, and make basic usage work correctly. Also, add a Eli Friedman
simple test that actually does VLA codegen. Note that despite the fact that the alloca isn't in the entry block, it should dominate all uses; this is guaranteed by the restrictions on goto into VLA scope in C99. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61291 91177308-0d34-0410-b5e6-96231b3b80d8
