* An insomniac stab at making block declarations list the variables they closeJohn McCall2011-02-021-1/+1
| | | | | | | on, as well as more reliably limiting invalid references to locals from nested scopes. llvm-svn: 124721
* Use RecordLayout::getBaseClassOffset() where CharUnits are needed instead ofKen Dyck2011-01-261-7/+4
| | | | | | converting getBaseClassOffsetInBits() to CharUnits. llvm-svn: 124274
* Fix the computation of alignment for fields of packed+aligned structs.John McCall2011-01-201-8/+1
| | | | | | Part of the fix for PR8413. llvm-svn: 123904
* Replace calls to CharUnits::fromQuantity() with onesKen Dyck2011-01-181-13/+8
| | | | | | ASTContext::toCharUnitsFromBits() when converting from bit sizes to char units. llvm-svn: 123715
* Introduce a new expression kind, SubstNonTypeTemplateParmPackExpr,Douglas Gregor2011-01-151-0/+1
| | | | | | | | | that captures the substitution of a non-type template argument pack for a non-type template parameter pack within a pack expansion that cannot be fully expanded. This follows the approach taken by SubstTemplateTypeParmPackType. llvm-svn: 123506
* Replace a literal '8' with getCharWidth().Ken Dyck2011-01-141-1/+2
| | | | llvm-svn: 123421
* PR3558: mark "logically const" accessor methods in ASTContext as const,Jay Foad2011-01-121-14/+16
| | | | | | | and mark the fields they use as mutable. This allows us to remove a few const_casts. llvm-svn: 123314
* Implement the sizeof...(pack) expression to compute the length of aDouglas Gregor2011-01-041-1/+9
| | | | | | | | | parameter pack. Note that we're missing proper libclang support for the new SizeOfPackExpr expression node. llvm-svn: 122813
* Implement support for pack expansions whose pattern is a non-typeDouglas Gregor2011-01-031-0/+1
| | | | | | | | | | | | | | | | | template argument (described by an expression, of course). For example: template<int...> struct int_tuple { }; template<int ...Values> struct square { typedef int_tuple<(Values*Values)...> type; }; It also lays the foundation for pack expansions in an initializer-list. llvm-svn: 122751
* Change all self assignments X=X to (void)X, so that we can turn on aJeffrey Yasskin2010-12-231-1/+1
| | | | | | | | | new gcc warning that complains on self-assignments and self-initializations. Fix one bug found by the warning, in which one clang::OverloadCandidate constructor failed to initialize its FunctionTemplate member. llvm-svn: 122459
* Rewrite ComplexExprEvaluator::VisitCastExpr to use cast kinds, and fixJohn McCall2010-12-141-78/+109
| | | | | | | the basic casting logic to insert intermediate casts and preserve the exact complex-cast design. Fixes a crash in the test suite. llvm-svn: 121776

* PR5207: Change APInt methods trunc(), sext(), zext(), sextOrTrunc() andJay Foad2010-12-071-4/+3
| | | | | | | | zextOrTrunc(), and APSInt methods extend(), extOrTrunc() and new method trunc(), to be const and to return a new value instead of modifying the object in place. llvm-svn: 121121
* Type traits intrinsic implementation: __is_base_of(T, U)Francois Pichet2010-12-071-0/+5
| | | | | | New AST node introduced: BinaryTypeTraitExpr; to be reused for more intrinsics. llvm-svn: 121074
* Rename CXXExprWithTemporaries -> ExprWithCleanups; there's no theoreticalJohn McCall2010-12-061-1/+1
| | | | | | reason this is limited to C++, and it's certainly not limited to temporaries. llvm-svn: 120996
* Simplify the ASTs by consolidating ObjCImplicitGetterSetterExpr and ↵John McCall2010-12-021-1/+0
| | | | | | | | ObjCPropertyRefExpr into the latter. llvm-svn: 120643
* Kill CK_Unknown and flesh out the documentation for the existing CastKinds.John McCall2010-11-161-29/+0
| | | | llvm-svn: 119331
* Add a new expression kind, OpaqueValueExpr, which is useful forJohn McCall2010-11-151-0/+1
| | | | | | | certain internal type-checking procedures as well as for representing certain implicitly-generated operations. Uses to follow. llvm-svn: 119289
* Add a few more complex-related cast kinds that arise due to arbitraryJohn McCall2010-11-141-1/+8
| | | | | | | | | | implicit conversions; the last batch was specific to promotions. I think this is the full set we need. I do think dividing the cast kinds into floating and integral is probably a good idea. Annotate a *lot* more C casts with useful cast kinds. llvm-svn: 119036
* Introduce five new cast kinds for various conversions into andJohn McCall2010-11-131-0/+2

* Split out -Wconversion warnings about constant precision into theirJohn McCall2010-11-091-3/+16
| | | | | | | | | | | own subcategory, -Wconstant-conversion, which is on by default. Tweak the constant folder to give better results in the invalid case of a negative shift amount. Implements rdar://problem/6792488 llvm-svn: 118636
* Rename getBaseClassOffset to getBaseClassOffsetInBits and introduce a ↵Anders Carlsson2010-10-311-2/+2
| | | | | | getBaseClassOffset which returns the offset in CharUnits. Do the same thing for getVBaseClassOffset. llvm-svn: 117881
* Teach the constant expr evaluator about derived-to-base casts when no ↵Anders Carlsson2010-10-311-0/+36

* Implement C++0x user-defined string literals.Alexis Hunt2010-08-291-1/+2
| | | | | | | | | | The extra data stored on user-defined literal Tokens is stored in extra allocated memory, which is managed by the PreprocessorLexer because there isn't a better place to put it that makes sure it gets deallocated, but only after it's used up. My testing has shown no significant slowdown as a result, but independent testing would be appreciated. llvm-svn: 112458
* GCC didn't care for my attempt at API compatibility, so brute-force everythingJohn McCall2010-08-251-116/+116

* Get rid of isObjectType; when C++ says "object type", it generallyEli Friedman2010-08-051-1/+1
| | | | | | | just means "not a function type", not "not a function type or void". This changes behavior slightly, but generally in a way which accepts more code. llvm-svn: 110303
* Fix namespace polution.Dan Gohman2010-07-261-1/+5
| | | | llvm-svn: 109440
* Introduce a new cast kind for an "lvalue bitcast", which handlesDouglas Gregor2010-07-131-0/+1
| | | | | | | | | | | | | | | | reinterpret_casts (possibly indirectly via C-style/functional casts) on values, e.g., int i; reinterpret_cast<short&>(i); The IR generated for this is essentially the same as for *reinterpret_cast<short*>(&i). Fixes PR6437, PR7593, and PR7344. llvm-svn: 108294

| | | | | | | | | | in C++ that involve both integral and enumeration types. Convert all of the callers to Type::isIntegralType() that are meant to work with both integral and enumeration types over to Type::isIntegralOrEnumerationType(), to prepare to eliminate enumeration types as integral types. llvm-svn: 106071
