2009-02-13Add basic support for C++ name mangling according to the Itanium C++Douglas Gregor
ABI to the CodeGen library. Since C++ code-generation is so incomplete, we can't exercise much of this mangling code. However, a few smoke tests show that it's doing the same thing as GCC. When C++ codegen matures, we'll extend the ABI tester to verify name-mangling as well, and complete the implementation here. At this point, the major client of name mangling is in the uses of the new "overloadable" attribute in C, which allows overloading. Any "overloadable" function in C (or in an extern "C" block in C++) will be mangled the same way that the corresponding C++ function would be mangled. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64413 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-10Function parameters for PIC16 are like local variables. So use the keyword ↵Sanjiv Gupta
".auto." to mangle their names. The working of PIC16AsmPrinter relies on that keyword currently. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64198 91177308-0d34-0410-b5e6-96231b3b80d8

Fixes PR3491. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63879 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-03Targets that don't have stack use global address space for parameters.Sanjiv Gupta
Specify external linkage for such globals so that llvm optimizer do not assume there values initialized as zero. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63636 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-25Rename Expr::isConstantExpr to Expr::isConstantInitializer; this more Eli Friedman
accurately states what the function is trying to do and how it is different from Expr::isEvaluatable. Also get rid of a parameter that is both unused and inaccurate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62951 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-16more SourceLocation lexicon change: instead of referring to theChris Lattner
"logical" location, refer to the "instantiation" location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62316 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

2008-12-20Change EmitVLASize to take a QualType that must be a variably modified type.Anders Carlsson
Emit the size even if the declared type is a variably modified type. This lets us handle void f(int n) { int (*a)[n]; printf("size: %d\n", sizeof(*a)); } git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61285 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-24Migrate some stuff from NamedDecl::getName() to Chris Lattner
NamedDecl::getNameAsString() to make it more explicit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59937 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-24Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make itChris Lattner
assert if the name is not an identifier. Update callers to do the right thing and avoid this method in unsafe cases. This also fixes an objc warning that was missing a space, and migrates a couple more to taking IdentifierInfo and QualTypes instead of std::strings. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59936 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-17Introduction the DeclarationName class, as a single, general method ofDouglas Gregor
representing the names of declarations in the C family of languages. DeclarationName is used in NamedDecl to store the name of the declaration (naturally), and ObjCMethodDecl is now a NamedDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@59441 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-10reimplement debug info generation in terms of DebugInfo.h instead ofChris Lattner
using MachineModuleInfo. This runs at about the same speed as the old code, but fixes a bunch of bugs and is simpler and shorter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58971 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-31Made the mechanism of defining preprocessor defs for maxint, ptrdiff_t, wcharSanjiv Gupta
etc more generic. For some targets, long may not be equal to pointer size. For example: PIC16 has int as i16, ptr as i16 but long as i32. Also fixed a few build warnings in assert() functions in CFRefCount.cpp, CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@58501 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-17Change CGDebugInfo::setLocation to just ignore invalid locations. ThisDaniel Dunbar
simplifies clients. Also, add assert that RegionStack is empty when the CGDebugInfo is destroyed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57684 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-15Simplify handling of struct/union/class tags.Argyrios Kyrtzidis
Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl. Cleans up the code a bit and better reflects that Decl class structure. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57541 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-16Add NeXT runtime support for generating methods.Daniel Dunbar
Change CodeGenFunction::EmitParmDecl to take either a ParmVarDecl or an ImplicitParamDecl. Drop hasAggregateLLVMType from CodeGenModule.cpp (use version in CodeGenFunction). Change the Objective-C method generation to use EmitParmDecl for implicit parameters. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54838 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-13Basic support for volatile loads and stores. Stores the volatile Eli Friedman

2008-06-08Don't crash emitting an initializer for a static local with union type. Eli Friedman
This fix just makes sure to construct the global with the appropriate type, and fixes up the one user this affects to compensate. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52084 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-22Change uses of llvm::Type::isFirstClassType to use the newDan Gohman
llvm::Type::isSingleValueType. Currently these two functions have the same behavior, but soon isFirstClassType will return true for struct and array types. Clang may some day want to use of isFirstClassType for some of these some day as an optimization, but it'll require some consideration. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51446 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-08Add basic support for the pic-* target triples and add support forChris Lattner

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
