| | | | llvm-svn: 68170
* Change UsedArray to be a vector of WeakVH to fix a dangling pointer problem ↵Chris Lattner2009-03-311-1/+2

* Do not emit debug information for variables while generating optimized code. ↵Devang Patel2009-03-271-0/+1
| | | | | | The llvm optimizer and code generator are not yet ready to support optimized code debugging. llvm-svn: 67876
* most of this is plumbing to get CompileOptions down into Chris Lattner2009-03-261-8/+7
| | | | | | | CodeGenModule. Once there, add a new NoCommon option to it and implement -fno-common. llvm-svn: 67735
* switch getBuiltinLibFunction to use the new GetOrCreateLLVMFunction Chris Lattner2009-03-221-5/+0
| | | | | | | | functionality, fixing a crash on the attached testcase. Eliminate the BuiltinFunctions cache, as it can contain dangling pointers. This fixes a bunch of valgrind errors on test/CodeGen/builtins.c llvm-svn: 67484

* code cleanups, rename EmitForwardFunctionDefinition -> Chris Lattner2009-03-211-4/+4
| | | | | | | CreateFunctionPrototypeIR, though my next patch will eliminate it entirely. llvm-svn: 67443

* Backout r66408, we don't want handling of globals to rely on theDaniel Dunbar2009-03-091-16/+13

* (LLVM svn up) Generalize RuntimeFunctions to RuntimeGlobals and addDaniel Dunbar2009-03-061-5/+10
| | | | | | | | | | | | | | CodeGenModule::CreateRuntimeVariable. - No real functionality change; although we now assert on silly things like: -- int objc_exception_throw; void f0() { @throw(@"A"); } -- instead of accepting it. llvm-svn: 66292
* Move more of the blocks code up and out.Mike Stump2009-03-041-2/+0
| | | | llvm-svn: 66046
* Move more of blocks codegen out of CodeGenModule and into theMike Stump2009-03-041-24/+1
| | | | | | | | | BlockModule. No functionality change. This should help people that don't want to know anything about blocks not be confused by the overloaded use of the term block or nor want to see all the blocks goop. llvm-svn: 66042
* Start the migration of more of the blocks code out of sight for mostMike Stump2009-03-041-10/+2
| | | | | | people. De-duplicates BLOCK_NEEDS_FREE and friends. llvm-svn: 66034

* Fix PR3612. We ensure that we add builtins to the GlobalDeclMap andMike Stump2009-02-271-2/+2
| | | | | | | | | we ensure that things added to the module can be found even when they are not in GlobalDeclMap. The later is for increased flexibility, should someone want to do something tricky like extern "Ada" in the same module. llvm-svn: 65657
* first wave of fixes for @encode sema support. This is part of PR3648.Chris Lattner2009-02-241-0/+5
| | | | | | | The big difference here is that (like string literal) @encode has array type, not pointer type. llvm-svn: 65391
* Prevent accidental copying of CodeGenFunction and CodeGenModule.Anders Carlsson2009-02-241-0/+3
| | | | llvm-svn: 65372
* Don't emit K&R unprototyped function definitions as varargs.Daniel Dunbar2009-02-191-1/+10
| | | | | | - <rdar://problem/6584606> clang/x86-64 - too many reg saves llvm-svn: 65032
* More codegen for blocks. The type of block literals should be better.Mike Stump2009-02-191-0/+2
| | | | | | The size calculation is improved. llvm-svn: 64994
* Address Chris's comments regarding C++ name mangling.Douglas Gregor2009-02-181-9/+19
| | | | llvm-svn: 64984
* Change EmitConstantExpr to allow failure.Daniel Dunbar2009-02-171-0/+5
| | | | | | | | | | | | | | IRgen no longer relies on isConstantInitializer, instead we just try to emit the constant. If that fails then in C we emit an error unsupported (this occurs when Sema accepted something that it doesn't know how to fold, and IRgen doesn't know how to emit) and in C++ we emit a guarded initializer. This ends up handling a few more cases, because IRgen was actually able to emit some of the constants Sema accepts but can't Evaluate(). For example, PR3398. llvm-svn: 64780
* Use getNameAsCString instead of getNameAsString and reflow the type.Mike Stump2009-02-141-1/+1
| | | | | | Thanks Anders. llvm-svn: 64571
* Generate the helper function for blocks. Now basic codegen isMike Stump2009-02-141-1/+1

* IRgen support for attribute used.Daniel Dunbar2009-02-131-0/+7
| | | | | | - PR3566 llvm-svn: 64492
* Pull MayDeferGeneration out of EmitGlobal.Daniel Dunbar2009-02-131-0/+5
| | | | | | | | - Fix emission of static functions with constructor attribute while I was here. <rdar://problem/6140899> [codegen] "static" and attribute-constructor interact poorly llvm-svn: 64488
* Rename EmitStatics (etc) to EmitDeferred; provide basic infrastructureDaniel Dunbar2009-02-131-7/+25

* Add basic support for C++ name mangling according to the Itanium C++Douglas Gregor2009-02-131-0/+4
| | | | | | | | | | | | | | | | 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. llvm-svn: 64413
* Add a very basic implemenation of global blocks. This needs to be cleaned up.Anders Carlsson2009-02-121-0/+7
| | | | llvm-svn: 64387
* More ABI API cleanup.Daniel Dunbar2009-02-021-3/+3
| | | | | | | - Lift CGFunctionInfo creation above ReturnTypeUsesSret and EmitFunction{Epi,Pro}log. llvm-svn: 63553
* Kill off CGCallInfo, always use CGFunctionInfo for encapsulatingDaniel Dunbar2009-01-311-2/+1
| | | | | | function/call info. llvm-svn: 63466
* Fix the bug that would cause Python to crash at startup.Anders Carlsson2009-01-041-1/+3
| | | | | | | When emitting the static variables we need to make sure that the order is preserved. Fix this by making StaticDecls a std::list which has O(1) random removal. llvm-svn: 61621
* Add option argument to GetAddrOfConstantString to use for name ofDaniel Dunbar2008-10-171-3/+11
| | | | | | | (first) global holding the string. - No functionality change. llvm-svn: 57736
* Add simple interface for protecting runtime functions from nameDaniel Dunbar2008-10-011-0/+13
| | | | | | | | | | | | | | | | | collisions. - Provide CodeGenModule::CreateRuntimeFunction which guarantees that the function it creates will have the provided name in the final module. This allows the runtime to have its functions protected from declarations of the same name in the source code. - One could argue that this is a reason to abuse the llvm::Module namespace for dealing with function redeclarations. However, that approach seems conceptually flawed to me. This one also happens to be somewhat more efficient. No functionality change. llvm-svn: 56899
