2008-10-06Make sema and codegen allow __builtin___CFStringMakeConstantString as a validChris Lattner
constant lvalue. Implement this in codegen by moving the code out of CGBuiltin into EmitConstantExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57163 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-06instead of making codegen try to know about all of the builtins to generateChris Lattner
constants for them, just use the constant evaluator to do the job. This also fixes crashes on 'unknown constant builtins'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57155 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-16Change WarnUnsupported to ErrorUnsupported (in name and in practice).Daniel Dunbar
- We are beyond the point where this shows up often and when it does generating miscompiled files is bad. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54836 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Add GetAddrOfConstantCString methodDaniel Dunbar
- Returns addr of constant for argument + '\0'. - I couldn't think of a better name. - Move appropriate users of GetAddrOfConstantString to this. Rename getStringForStringLiteral to GetStringForStringLiteral. Add GetAddrOfConstantStringFromLiteral - This combines GetAddrOfConstantString and GetStringForStringLiteral. This method can be, but is not yet, more efficient. Change GetAddrOfConstantString to not add terminating '\0' - <rdar://problem/6140956> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54768 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-13Change ObjCRuntime GenerateProtocol[Ref] methods to takeDaniel Dunbar
ObjCProtocolDecl directly. Implement CodeGen support for forward protocol decls (no-ops are so nice to implement). Also moved CGObjCRuntime.h out of CodeGenModule.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54709 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-12Add ObjC constant string support for NeXT.Daniel Dunbar
Changed CGObjCRuntime::GenerateConstantString interface to take std::string instead of char* and size. Change ObjC functions which call on GenerateConstantString to bitcast result to appropriate type. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54659 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11Change CodeGenModule to only create ObjC runtime for ObjC filesDaniel Dunbar
- Changed CodeGenModule::getObjCRuntime to return reference. - Added CodeGenModule::hasObjCRuntime predicate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54645 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-11More #include cleaningDaniel Dunbar
- Remove internal uses of AST.h git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54628 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-10Back out r54608 (inline string literals were getting an extra '\0')Daniel Dunbar
temporarily, I assumed GetAddrForConstantString literal was being used consistently but it doesn't look like it is. Factored out a CodeGenModule::getStringForStringLiteral which handles extracting a std::string for the bytes of a StringLiteral, padded to match the type. Update EmitLValue to use getStringForStringLiteral, this was previously not padding strings correctly. Good thing we only emit strings in 4 different places! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54621 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-10Fix crash during initialization of a bitfield which followed a zeroDaniel Dunbar
length element. Fix some 80-col violations. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54610 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
2008-07-29Rework 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

2008-06-21"this patch adds code generation hooks for Objective-C constant strings. It ↵Chris Lattner
also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet." Patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52599 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-07Fix crash with conversion to an address-space-qualified pointer. Bug Eli Friedman
reported on cfe-dev by Cédric Venet. Note that I seriously doubt that this perticular construct is useful, though: it's a pointer in an alternate address space pointing into unqualified address space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52076 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-30Fix and enable generating general union initializers. Essentially, what Eli Friedman
this does is reconstruct the type for structs and arrays if the type wouldn't be compatible otherwise. The assertion about packing in the struct type reconstruction code sucks, but I don't see any obvious way to fix it. Maybe we need a general utility method to take a list of types and alignments and try to construct an unpacked type if possible? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51785 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-30Fix constant vector init for initializer lists with an incomplete list Eli Friedman
of elements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51769 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-30Some additions to constant initializer generation code. Adds Eli Friedman
bit-field initialization; ugly code, X86-only, but it works, at least for basic stuff. Separates/adds union initialization; currently disabled, though, because the struct/array code needs modifications to support elements of the wrong type. Fixes PR2381 and PR2309 with the bit-field initialization. And NetHack compiles and appears to work with a few tweaks (to work around the lack of transparent_union support, and clang being a bit strict about conflicting declarations). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51763 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-29Add codegen support for a few more kinds of initializer constant Eli Friedman
expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51677 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-20Restructure constant structure init codegen so that it's possible to Eli Friedman
implement bitfield codegen (although I don't envy the person who implements it). This also prevents a crash on code like that from PR2309 (it's still broken, but it fails more gracefully). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51285 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

2008-03-15Make 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
