* fix CreateTempAlloca to not set a name on the alloca for temporariesChris Lattner2009-03-221-3/+5
| | | | | | | | | in release-assert builds. For automatic variables, explicitly set a name with setName that does not make a temporary std::string. This speeds up -emit-llvm-only -disable-free on PR3810 by 4.6% llvm-svn: 67459

* Don't mangle names of local variables.Daniel Dunbar2009-03-051-2/+2
| | | | | | | | - For one thing, this adds unneeded overhead; for another, this routine can be used to emit unnamed decls which we shouldn't try to mangle. llvm-svn: 66212

* Last part of PR3254: use the same alignment computation in Sema and Eli Friedman2009-02-221-4/+1
| | | | | | | CodeGen. I'm not sure whether this actually makes any visible difference, but it's better to be consistent anyway. llvm-svn: 65259

* Address Chris's comments regarding C++ name mangling.Douglas Gregor2009-02-181-2/+2
| | | | llvm-svn: 64984
* Change EmitConstantExpr to allow failure.Daniel Dunbar2009-02-171-6/+11
| | | | | | | | | | | | | | 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
* Set constant bit on static block vars as well. Patch by Anders Johnson!qDaniel Dunbar2009-02-131-1/+1

* IRgen support for attribute used.Daniel Dunbar2009-02-131-1/+3

* Add basic support for C++ name mangling according to the Itanium C++Douglas Gregor2009-02-131-2/+2
| | | | | | | | | | | | | | | | 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
* Honor attribute section on static block var decls.Daniel Dunbar2009-02-121-0/+4
| | | | llvm-svn: 64411
* Function parameters for PIC16 are like local variables. So use the keyword ↵Sanjiv Gupta2009-02-101-1/+1
| | | | | | ".auto." to mangle their names. The working of PIC16AsmPrinter relies on that keyword currently. llvm-svn: 64198
* Use the new cleanup infrastructure for VLAs. The next iteration of patches ↵Anders Carlsson2009-02-091-2/+12
| | | | | | will remove the old Obj-C EH cleanup code. llvm-svn: 64161
* Emit a cleanup block for the cleanup attributeAnders Carlsson2009-02-071-0/+16

* Fixup goto codegen in and around VLAs.Mike Stump2009-02-071-1/+1
| | | | llvm-svn: 64014
* Follow Eli's advice and store the VLA size with the native size_t type. ↵Anders Carlsson2009-02-051-0/+3
| | | | | | Fixes PR3491. llvm-svn: 63879
* Targets that don't have stack use global address space for parameters.Sanjiv Gupta2009-02-031-5/+15
| | | | | | | Specify external linkage for such globals so that llvm optimizer do not assume there values initialized as zero. llvm-svn: 63636
* Rename Expr::isConstantExpr to Expr::isConstantInitializer; this more Eli Friedman2009-01-251-1/+1
| | | | | | | | 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. llvm-svn: 62951
* more SourceLocation lexicon change: instead of referring to theChris Lattner2009-01-161-1/+2
| | | | | | "logical" location, refer to the "instantiation" location. llvm-svn: 62316
* Make VLAs usable, and make basic usage work correctly. Also, add a Eli Friedman2008-12-201-10/+2
| | | | | | | | | | 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. llvm-svn: 61291
* Handle typedefs to VLAs (Emit the size expr when we encounter the typedefAnders Carlsson2008-12-201-1/+8
| | | | llvm-svn: 61290
* Change EmitVLASize to take a QualType that must be a variably modified type.Anders Carlsson2008-12-201-3/+4
| | | | | | | | | | | | 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)); } llvm-svn: 61285
* Split up emitting of VLA sizes and getting the size of a VLA.Anders Carlsson2008-12-201-1/+1
| | | | llvm-svn: 61284
* Add some ErrorUnsupported calls and turn on VLA codegen again.Anders Carlsson2008-12-201-9/+0

* disable Anders' recent VLA patch, this fixes PR3209.Chris Lattner2008-12-131-0/+9
| | | | llvm-svn: 60989
* Implement allocation and sizeof VLAs. This is very basic for now.Anders Carlsson2008-12-121-5/+30
| | | | llvm-svn: 60943
* Migrate some stuff from NamedDecl::getName() to Chris Lattner2008-11-241-4/+4
| | | | | | NamedDecl::getNameAsString() to make it more explicit. llvm-svn: 59937
* Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make itChris Lattner2008-11-241-2/+4
| | | | | | | | | 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. llvm-svn: 59936
* Introduction the DeclarationName class, as a single, general method ofDouglas Gregor2008-11-171-2/+2
| | | | | | | | 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. llvm-svn: 59441
* reimplement debug info generation in terms of DebugInfo.h instead ofChris Lattner2008-11-101-10/+4
| | | | | | | using MachineModuleInfo. This runs at about the same speed as the old code, but fixes a bunch of bugs and is simpler and shorter. llvm-svn: 58971
* Made the mechanism of defining preprocessor defs for maxint, ptrdiff_t, wcharSanjiv Gupta2008-10-311-1/+1
| | | | | | | | | | 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. llvm-svn: 58501
