2008-08-10Bug fix, inline string literals were getting an extra '\0'.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54608 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-06Implement GNU asm-label extension support in CodeGen. This fixesDaniel Dunbar
scimark2 on Darwin. - Added Sema support for asm-label on variables, which I forgot before. - Update CodeGen to use GlobalDeclMap to determine if static Decls require emission (instead of LLVM module name lookup). Important since the Decl name and the LLVM module name can differ. - <rdar://problem/6116729> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54388 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-05Change CodeGen of global decls to key off of the name (instead ofDaniel Dunbar
having multiple bindings from all the possible decls which conceptually map to the same global). - This eliminates CodeGen depending on the LLVM module for name lookup. - This also eliminates the need for ReplaceMapValuesWith (hurrah). - This handles lookups for FunctionDecls correctly in the presence of aliases, this was previously broken. - WIP: Can still clean up & unify variable and function emission. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54382 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-05Refactored driver logic for CodeGen into LLVMCodeGenWriter. This ↵Ted Kremenek
ASTConsumer layers on top of LLVMCodeGen (another existing ASTConsumer) to emit bitcode files to disk. This layering takes this logic out of clang.cpp and puts it directly into the ASTConsumer interface. The benefit is that now --emit-llvm works with both serialized ASTs and regular source files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54364 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-04Finally fix PR2189. This makes a fairly invasive but important change toChris Lattner
move getAsArrayType into ASTContext instead of being a method on type. This is required because getAsArrayType(const AT), where AT is a typedef for "int[10]" needs to return ArrayType(const int, 10). Fixing this greatly simplifies getArrayDecayedType, which is a good sign. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54317 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-01Support constructor and destructor attributes in CodeGenDaniel Dunbar
- There is an miscompilation issue remaining due to a poor interaction between the delayed emission of static functions and the emission of constructors, but that already existed prior to this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54258 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-30Change CodeGenModule GlobalDeclMap to directly reference globalsDaniel Dunbar
instead of mapping the decl to a bitcast of the global to the correct type. - GetAddrOf{Function,GlobalVar} introduce the bitcast on every use now. - This solves a problem where a dangling pointer could be introduced by the RAUW done when replacing a forward or tentative definition. See testcase for more details. - Fixes <rdar://problem/6108358> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54211 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
2008-07-29Fix codegen of chained declarationsDaniel Dunbar
- Killed useless CodeGenModule::EmitGlobalVarDeclarator, instead just recurse on any ScopedDecl. - Fix for <rdar://problem/6093838> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54162 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21move two more lists of protocols over to use ObjCList<ObjCProtocolDecl>,Chris Lattner
simplifying code along the way and fixing a problem and memory leak or two. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53876 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-21introduce a new ObjCList templated class and start moving Chris Lattner
various objc lists over to it. First up, the protocol list on ObjCInterfaceDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53856 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-26refactor more objc codegen interfaces to pass around selectors soChris Lattner
we don't push strings into LLVM IR and then have to read them back out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52765 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-26give CreateObjCRuntime a full CGM so it can get whatever state it needs, Chris Lattner
instead of passing in just a couple random things it currently happens to use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52756 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-05Emit debug information for global and static variables when -g is specified.Sanjiv Gupta
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51993 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-04For setting attributes, don't assume there are ParamVarDecls available, Eli Friedman
because trying to access non-existent ParamVarDecls can crash. Testcase from the original source for PR2414. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51960 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
2008-05-30PR1893: Fix up the type of tentative definitions of incomplete array Eli Friedman
types so that they end up the correct size. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51787 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-30Allow the type of a global to be different from the type of its Eli Friedman
associated declaration. This is a prerequisite to handling general union initializations; for example, an array of unions involving pointers has to be turned into a struct because the elements can have incompatible types. I refactored the code a bit to make it more readable; now, the logic for definitions is all in EmitGlobalVarInit. The second parameter for GetAddrOfGlobalVar is now dead; I'll remove it separately. By itself, this patch should not cause any visible changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51783 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-30Always check that the definition of a function has the correct type. Eli Friedman
This fixes a crash on the included testcase (found in NetHack). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51767 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-29Add CodeGen support for alignment on globals, both for unusual natural Eli Friedman
alignment and alignment attributes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51676 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-29Tentative declarations are supposed to have common linkage, not weak. Eli Friedman
This change makes clang generate the same thing as llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51674 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-27The cache is working again; re-enable it.Eli Friedman

2008-05-27Add a more reliable check for whether a static declaration has already Eli Friedman
been used. In preparation for the fix to PR2360, but also a minor bug in its own right. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51583 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-26Emit memmove, not memcpy, for structure copies; this is unfortunately Eli Friedman
required for correctness in cases of copying a struct to itself or to an overlapping struct (itself for cases like *a = *a, and overlapping is possible with unions). Hopefully, this won't end up being a perf issue; LLVM *should* be able to optimize memmove to memcpy in a lot of cases, and for small copies the generated code *should* be mostly comparable. (In reality, LLVM is currently horrible at optimizing memmove, but that's a bug, not a fundamental issue.) gcc currently generates wrong code; that's http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32667. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51566 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
2008-05-20Disable the function address cache; this doesn't have any ill effects, Eli Friedman
as far as I can tell, and it fixes code like test/CodeGen/functions.c. (Whatever performance effect it might have, crashing on a construct like this isn't really acceptable; I've run into this multiple times.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51312 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-08Added -g command line options to clang for generating source level debug ↵Sanjiv Gupta
information. This patch currently enables generation of line number debug information (stoppoints) and region begin/end debug information. The new files CGDebugInfo.h and CGDebugInfo.cpp implements the debug info manager class CGDebugInfo. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50848 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-25remove the 'unused static' diagnostic from codegen. This should be Chris Lattner
reimplemented in Sema someday. This is tracked in PR2236. Until then disabling it removes some bogus diagnostics (see 2236). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50263 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

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
