* the big refactoring bits of PR3782.Rafael Espindola2010-03-301-3/+3
| | | | | | | | This introduces FunctionType::ExtInfo to hold the calling convention and the noreturn attribute. The next patch will extend it to include the regparm attribute and fix the bug. llvm-svn: 99920
* Rename CGVtableInfo to CodeGenVTables in preparation of adding another ↵Anders Carlsson2010-03-231-1/+1
| | | | | | VTableInfo class. llvm-svn: 99250
* Eliminate the default arguments to ASTContext::getFunctionType(),Douglas Gregor2010-02-211-1/+4
| | | | | | | | fixing up a few callers that thought they were propagating NoReturn information but were in fact saying something about exception specifications. llvm-svn: 96766
* More refactoring around constructor/destructor code generation.John McCall2010-02-191-73/+13
| | | | | | | | | | | | Fix some bugs with function-try-blocks and simplify normal try-block code generation. This implementation excludes a deleting destructor's call to operator delete() from the function-try-block, which I believe is correct but which I can't find straightforward support for at a moment's glance. llvm-svn: 96670
* Make deleting and complete dtor variants defer to other dtor variants byJohn McCall2010-02-181-12/+42
| | | | | | | | calling them as subroutines. This triggers whenever the alias optimization doesn't, i.e. when the dtor has linkonce linkage or there are virtual bases or it's the deleting dtor. llvm-svn: 96605
* Extract out function-body code generation into its own method. No functionalityJohn McCall2010-02-181-71/+55
| | | | | | change. llvm-svn: 96564
* IRgen optimization: cache the value of 'this' and 'vtt' instead ofJohn McCall2010-02-161-3/+9
| | | | | | | | repeatedly reloading from an alloca. We still need to create the alloca for debug info purposes (although we currently create it in all cases because of some abstraction boundaries that're hard to break down). llvm-svn: 96403
* IRgen: Switch 'retval' to use CreateIRTemp.Daniel Dunbar2010-02-161-2/+2
| | | | llvm-svn: 96376
* Pass inline keyword to optimizer as the new InlineHint function attribute.Jakob Stoklund Olesen2010-02-091-0/+10
| | | | | | | | | | At the moment the inlinehint attribute is ignored by the Inliner unless you pass a -respect-inlinehint option. This will soon be the default. The inlinehint attribute is set if the inline keyword is explicitly specified on any declaration. llvm-svn: 95623
* Make sure to set vtable pointers in the destructors as well.Anders Carlsson2010-02-071-0/+2
| | | | llvm-svn: 95525
* Standardize the parsing of function type attributes in a way thatJohn McCall2010-02-051-1/+3
| | | | | | | | | | | | follows (as conservatively as possible) gcc's current behavior: attributes written on return types that don't apply there are applied to the function instead, etc. Only parse CC attributes as type attributes, not as decl attributes; don't accepet noreturn as a decl attribute on ValueDecls, either (it still needs to apply to other decls, like blocks). Consistently consume CC/noreturn information throughout codegen; enforce this by removing their default values in CodeGenTypes::getFunctionInfo(). llvm-svn: 95436
* Rename StartConditionalBranch/FinishConditionalBranch to ↵Anders Carlsson2010-02-041-4/+4
| | | | | | BeginConditionalBranch/EndConditionalBranch. llvm-svn: 95308
* Fix a nasty bug where temporaries weren't marked as being conditional in ↵Anders Carlsson2010-01-241-0/+8
| | | | | | some cases. llvm-svn: 94341
* Emit human readable names for c/c++ functions. Avoid emitting linkage name ↵Devang Patel2010-01-141-7/+1
| | | | | | if it matches regular name. llvm-svn: 93383
* Roll out ASTContext::getTypeSizeInChars(), replacing instances ofKen Dyck2010-01-111-1/+1
| | | | | | | | | | "ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits ones as appropriate. Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, fromQuantity(), and getQuantity() for clarity. llvm-svn: 93153
* Correctly pass VTT parameters to constructors and destructors. The VTTs ↵Anders Carlsson2010-01-021-21/+2
| | | | | | aren't yet used in the ctors/dtors, but that will follow. llvm-svn: 92409
* Eliminate the ASTContext argument to CXXConstructorDecl::isCopyConstructor, ↵Douglas Gregor2009-12-221-1/+1
| | | | | | since the context is available in the Decl llvm-svn: 91862
* Switch codegen for -fcatch-undefined-bahavior over to __builtin_trapMike Stump2009-12-151-1/+1
| | | | | | instead of abort to improve codesize and codegen. llvm-svn: 91374
* Add support for detecting undefined shift behavior. WIP.Mike Stump2009-12-141-2/+2
| | | | llvm-svn: 91341
* Implement runtime checks for undefined behavior. WIP.Mike Stump2009-12-121-1/+2
| | | | | | | | | | | | | This implements a new flag -fcatch-undefined-behavior. The flag turns on additional runtime checks for: T a[I]; a[i] abort when i < 0 or i >= I. Future stuff includes shifts by >= bitwidth amounts. llvm-svn: 91198
* Get rid of static variable.Eli Friedman2009-12-101-1/+2
| | | | llvm-svn: 91041
* Ensure we only generate one terminate handler.Mike Stump2009-12-101-1/+1
| | | | llvm-svn: 90998
* Add cleanups for exceptional edges. WIP.Mike Stump2009-12-091-1/+5

* Use StringRef in CGDebugInfo::EmitFunctionStart.Benjamin Kramer2009-12-081-4/+1
| | | | llvm-svn: 90856
* Add codegen support for exception specifications. WIP.Mike Stump2009-12-071-0/+2

* Add support for function try blocks.Mike Stump2009-12-041-1/+10
| | | | llvm-svn: 90622
* Make functions returning a struct indirectly evaluate the returned structEli Friedman2009-12-041-3/+13
| | | | | | | directly into the sret pointer. This is an optimization in C, but is required for correctness in C++ for classes with a non-trivial copy constructor. llvm-svn: 90526
* More exception handling improvements... WIP.Mike Stump2009-12-021-9/+22
| | | | | | | | | | | Highlights include: Add a helper to generate __cxa_free_exception and _ZSt9terminatev. Add a region to handle EH object deallocation for ctor failures for throw. Add a terminate handler for __cxa_end_catch. A framework for adding cleanup actions for the exceptional edges only. llvm-svn: 90305
* Add VTT parameter to base ctors/dtors with virtual bases. (They aren't used ↵Anders Carlsson2009-11-251-1/+33

* This patch extends CleanupScope to support destructionFariborz Jahanian2009-11-041-7/+9
| | | | | | of array objects on block exit. Patch is by Anders Calrsson. llvm-svn: 86032
* Implement clang support for indirect branch and address of labelChris Lattner2009-10-281-0/+68
| | | | | | | | using the new LLVM support for this. This is temporarily hiding behind horrible and ugly #ifdefs until the time when the optimizer is stable (hopefully a week or so). Until then, lets make it "opt in" :) llvm-svn: 85446
* factor a creation of Int32Ty.Chris Lattner2009-10-281-4/+3
| | | | llvm-svn: 85422
* Fixup the return type of functions.Mike Stump2009-10-231-2/+4
| | | | llvm-svn: 84922
* reimplement codegen for indirect goto with the following advantages:Chris Lattner2009-10-131-31/+72
| | | | | | | | | | | | | 1. CGF now has fewer bytes of state (one pointer instead of a vector). 2. The generated code is determinstic, instead of getting labels in 'map order' based on pointer addresses. 3. Clang now emits one 'indirect goto switch' for each function, instead of one for each indirect goto. This fixes an M*N = N^2 IR size issue when there are lots of address-taken labels and lots of indirect gotos. 4. This also makes the default cause do something useful, reducing the size of the jump table needed (by one). llvm-svn: 83952
* number address-taken labels from 1. This allows 0 to be used as a sentinelChris Lattner2009-10-131-1/+1
| | | | | | | for a null pointer. In other words, "&&foo != NULL" will always work out to true. llvm-svn: 83948
* Use the new Type::getInt8PtrTy method. This should probably be used in a lotChris Lattner2009-10-131-1/+1
| | | | | | more places in clang codegen now. llvm-svn: 83947
* Emit the destructor epilogue in a cleanup block so a return from a ↵Anders Carlsson2009-10-061-1/+20
| | | | | | destructor body still calls the epilogue. llvm-svn: 83397
* CodeGen may see out-of-line declarations of the various special memberDouglas Gregor2009-10-011-14/+23
| | | | | | | | | | | functions when they are explicitly declared, e.g., via a function template specialization or explicit template instantiation declaration. Don't try to synthesize bodies for the special member functions in this case; rather, check whether we have an implicit declaration and, if so, synthesize the appropriate function body. Fixes PR5084. llvm-svn: 83212
