2008-08-04Avoid creating dummy block when no indirect gotos are present.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54322 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-04Add CodeGen support for indirect goto.Daniel Dunbar
- Follows emission scheme used by llvm-gcc, i.e. invent an id for each label whose address is taken and replace each indirect goto by a switch to each possible target. - Currently we emit a switch for each indirect goto instead of merging them as llvm-gcc does. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54318 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-29Rework codegen emission of globalsDaniel Dunbar
- No (intended) functionality change. - Primary purpose is to clearly separate (lazy) construction of globals that are a forward declaration or tentative definition from those that are the final definition. - Lazy construction is now encapsulated in GetAddrOf{Function,GlobalVar} while final definitions are constructed in EmitGlobal{Function,Var}Definition. - External interface for dealing with globals is now limited to EmitGlobal and GetAddrOf{Function,GlobalVar}. - Also updated helper functions dealing with statics, annotations, and ctors to be private. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54179 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-17Change self/_cmd to be instances of ImplicitParamDecl instead of ParmVarDecl.Chris Lattner
Patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52422 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-13Basic support for volatile loads and stores. Stores the volatile Eli Friedman
qualifier in the lvalue, and changes lvalue loads/stores to honor the volatile flag. Places which need some further attention are marked with FIXMEs. Patch by Cédric Venet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52264 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-01First cut at setting attributes for functions and calls; this puts us Eli Friedman
much closer to passing the gcc struct layout tests. It might be possible to refactor this a bit, but I'm not sure there's actually enough common code for that to be useful. To get the calling convention completely correct, a bit of platform-specific code is necessary even for x86-Linux. On x86-Linux, the alignment of function parameters is extremely strange; as far as I can tell, it's always 4 except for SSE vectors or structs containing SSE vectors. I'm continuing to investigate this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51839 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-01Support for code generation of Objective-C top-level language constructs.Anton Korobeynikov
Implemented by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51835 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-25Generate subprogram debug info with -g.Sanjiv Gupta
Also take care of freeing memory at the right places. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51553 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-22Make debugging information usable. This is barebones, but it makes -g Eli Friedman
actually work (instead of crashing llc), and there's enough info emitted to get line number information in gdb. This should hopefully be helpful for debugging non-working programs. I got rid of the begin/endregion calls because the implementation wasn't working; someone who knows the debugging info a bit better might try to add it. I really have no clue how a compiler is supposed to emit them. This commit shouldn't have any effect without -g. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51404 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-22Move getAccessedFieldNo out of lib/AST/Expr.cpp intoDan Gohman
lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to use its own enum for visibility types instead of using llvm::GlobalValue::VisibilityTypes. These changes eliminate dependencies in the AST library on LLVM's VMCore library. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51398 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-04if a decl is both 'static' and weak or static and inline, its linkageChris Lattner
type should be internal, not weak/linkonce. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50611 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Remove FileVarDecl and BlockVarDecl. They are replaced by ↵Steve Naroff
VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl(). This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49748 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-30some cleanups on top of David's patch. There are still twoChris Lattner
remaining open issues I've communicated to him: 1) self can be assigned to, and his patch didn't handle it correctly. 2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses all parent class ivars) and flattens classes. If A derives from B, and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}. David, please review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48970 91177308-0d34-0410-b5e6-96231b3b80d8

etoile runtime, patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48969 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
