2008-05-20Add codegen support for stack address intrinsics.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51309 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-20Implement codegen for comma operator for structs.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51304 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
2008-05-20Remove code that shouldn't have any effect anymore.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51284 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-19Implement CodeGen for __builtin_memcpy.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51282 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-19Fix the emission of expressions like char a[10] = "asdf"; previously, Eli Friedman
they were causing bad code to be emitted. There are two fixes here: one makes sure we emit a string that is long enough, and one makes sure we properly handle string initialization in init lists. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51259 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-17Fix support for _Bool bitfields. The issue is that the bitfield width Eli Friedman
used for _Bool is not the same as the primitive width (which for _Bool is 1 bit). The load and store changes add some casts to make the types consistent. The EmitLValue changes make sure that the pointer is of an appropriate type for loading the bitfield. This isn't perfect, but it's an improvement, and getting everything right depends on actually laying out structs in an ABI-compliant way. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51224 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-16Backout of codegen-based fix to PR2334; this has been fixed differently Eli Friedman
at the Sema layer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51203 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-16Fix some prototypes, and implement some builtins until we have our header ↵Nate Begeman
files completed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51199 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-16Patch for PR2334, and a similar ObjC bug.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51193 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-15Handle a couple missing builtins that will go away eventually when the variousNate Begeman
intrin.h files are finished git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51137 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-14Implementation of __builtin_shufflevector, a portable builtin capable of Eli Friedman
expressing the full flexibility of the LLVM shufflevector instruction. The expected immediate usage is in *mmintrin.h, so that they don't depend on the mess of gcc-inherited (and not completely implemented) shuffle builtins. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51113 91177308-0d34-0410-b5e6-96231b3b80d8

2008-05-13Add support for init lists for complex variables.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51080 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50966 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-09Added support to generate some atomic operators (add, sub, and, or etc..)Mon P Wang
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50919 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-09Extend vector member references to include {.hi, .lo, .e, .o} which return aNate Begeman
vector of the same element type and half the width, with the high, low, even, and odd elements respectively. Allow member references to member references, so that .hi.hi gives you the high quarter of a vector. This is fairly convenient syntax for some insert/extract operations. Remove some unnecessary methods/types in the ExtVectorElementExpr class. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50892 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
2008-05-08Add basic support for the pic-* target triples and add support forChris Lattner
targets that do not support recursion (and thus codegen stack variables as globals). Patch contributed by Alireza Moshtaghi! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@50844 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

actually used. Warn about unused static functions and variables. This fixes PR1998. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49987 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-18Allow targets to override double size, alignment, and semantics, and tie thisNate Begeman
information into the IR type codegen. This allows a target to codegen the C 'double' type as either double or float. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49898 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

2008-04-09The dtor CGObjCRuntime::~CGObjCRuntime() was implemented twice, onceTed Kremenek
in CGObjCGNU.cpp and once in CGObjCEtoile.cpp. Moved its definition to CGObjC.cpp. This resolves a build error in Xcode, and also cleans things up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49429 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-04Fix PR2049, updating Eli's patch that fixes to mainline. This produces ↵Chris Lattner
incorrect code, but the codegen doesn't crash. I'll file a bugzilla for the AST being wrong. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49226 91177308-0d34-0410-b5e6-96231b3b80d8
