2010-12-13Variadic templates: extend Type, NestedNameSpecifier, TemplateName,Douglas Gregor
and TemplateArgument with an operation that determines whether there are any unexpanded parameter packs within that construct. Use this information to diagnose the appearance of the names of parameter packs that have not been expanded (C++ [temp.variadic]p5). Since this property is checked often (every declaration, ever expression statement, etc.), we extend Type and Expr with a bit storing the result of this computation, rather than walking the AST each time to determine whether any unexpanded parameter packs occur. This commit is deficient in several ways, which will be remedied with future commits: - Expr has a bit to store the presence of an unexpanded parameter pack, but it is never set. - The error messages don't point out where the unexpanded parameter packs were named in the type/expression, but they should. - We don't check for unexpanded parameter packs in all of the places where we should. - Testing is sparse, pending the resolution of the above three issues. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121724 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-13Fix PR8774 by restricting when hasInit returns true. Previously, itChandler Carruth
would return true if the initializer pointer union had *any* non-null pointer in it, even if the pointer wasn't one that would actually be returned via getInit(). This makes it more accurately model the logic of 'getInit() != NULL'. This still isn't completely satisfying. From a principled stance, I suspect we should make hasInit() and getInit() *always* return false and NULL (resp.) for ParmVarDecl. We shouldn't at the API level treat initializers and default arguments as the same thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121692 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-13Reduce the number of builtin operator overload candidates added in certainChandler Carruth
cases. First, omit all builtin overloads when no non-record type is in the set of candidate types. Second, avoid arithmetic type overloads for non-arithmetic or enumeral types (counting vector types as arithmetic due to Clang extensions). When heavily using constructs such as STL's '<<' based stream logging, this can have a significant impact. One logging-heavy test case's compile time dropped by 10% with this. Self-host shows 1-2% improvement in compile time, but that's likely in the noise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121665 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-12Move the functionality to mark all vtables of key functions as used withinChandler Carruth
a translation unit to the ActOnEndOfTranslationUnit function instead of doing it at the start of DefineUsedVTables. The latter is now called *recursively* during template instantiation, which causes an absolutely insane number of walks of every record decl in the translation unit. After this patch, an extremely template instantiation heavy test case's compile time drops by 10x, and we see between 15% and 20% improvement in average compile times across a project. This is just recovering a regression, it doesn't make anything faster than it was several weeks ago. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121644 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-12Finish cleaning up the static utility code for adding builtin operator overloadChandler Carruth
candidates. They're now wrapped in nice APIs which hide the tables, etc. Also removes some repetitive code from clients. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121634 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-12Clean up the helpers used to compute the usual arithmetic conversions' resultChandler Carruth
type. Localize all of the logic within a single function rather than spreading it throughout the class. Also fixes a buglet where we failed to check for a RHS arithmetic type wider than the LHS and return its canonical type. I've yet to produce a test case that breaks because of this, but it was spotted by inspection by folks on the IRC channel and is obviously correct now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121633 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-12Sink the logic to suppress builtin operator overloads in the presence ofChandler Carruth
user-defined operator overloads on the same enumeral types to the one place where it is used. In theory this removes wasted computation from several paths through this code, but I'm not aware of a case where it actually matters. This is mostly for cleanliness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121630 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-12Reorder the cases in the switch to be more logically grouped (to my mind). IfChandler Carruth
others have another ordering they would prefer, I'm all ears, but this one made it much easier for me to find the group of operators I'm interested in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121629 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-12Fix 80-column violations and reflowing some code to facilitate those fixes.Chandler Carruth

2010-12-12Begin the refactoring of how builtin operators are added to the overloadChandler Carruth
candidate set. This breaks apart a huge switch + goto system into distinct methods on a class. It also places the current mess of tables and other static state used in the process within that class. This is still a work in progress. I did a few simplifications that jumped out at me as I went, but I plan to iterate on this a bit before it's truly clean. However, this is easily the most invasive chunk. I benchmarked it on all-std-headers.cpp and an internal testcase that has a major hotspot in overload resolution and saw no real performance impact. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121623 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-10Any property declared in a class extension might have userFariborz Jahanian
declared setter or getter in current class extension or one of the other class extensions. Mark them as synthesized as property will be synthesized when property with same name is seen in the @implementation.

2010-12-10Do not assert on shifts of Neon polynomial types.Bob Wilson
Most Neon shift intrinsics do not have variants for polynomial types, but vsri_n and vsli_n do support them, and we need to properly range-check the shift immediates for them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121509 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-10Replace two QualType::getTypePtrOrNull() calls withDouglas Gregor
QualType::getTypePtr(). It turns out that cast_or_null/dyn_cast_or_null don't actually use simplify_type, so they're guaranteed to operator on non-NULL QualType or CanQualType objects. Good for a 0.6% win on 403.gcc's combine.c with -emit-llvm. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121495 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-10Do not substitute template types if template has dependent contextPeter Collingbourne
We should not substitute template types if the template has a dependent context because the template argument stack is not yet fully formed. Instead, defer substitution until the template has a non-dependent context (i.e. instantiation of an outer template). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121491 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-10Eliminate the branching in QualType::getTypePtr() by providing aDouglas Gregor
common base for ExtQuals and Type that stores the underlying type pointer. This results in a 2% performance win for -emit-llvm on a typical C file, with 1% memory growth in the AST. Note that there is an API change in this optimization: QualType::getTypePtr() can no longer be invoked on a NULL QualType. If the QualType might be NULL, use QualType::getTypePtrOrNull(). I've audited all uses of getTypePtr() in the code base and changed the appropriate uses over to getTypePtrOrNull(). A future optimization opportunity would be to distinguish between cast/dyn_cast and cast_or_null/dyn_cast_or_null; for the former, we could use getTypePtr() rather than getTypePtrOrNull(), to take another branch out of the cast/dyn_cast implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121489 91177308-0d34-0410-b5e6-96231b3b80d8

2010-12-10It's kindof silly that ExtQuals has an ASTContext&, and we can use thatJohn McCall
space better. Remove this reference. To make that work, change some APIs (most importantly, getDesugaredType()) to take an ASTContext& if they need to return a QualType. Simultaneously, diminish the need to return a QualType by introducing some useful APIs on SplitQualType, which is just a std::pair<const Type *, Qualifiers>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121478 91177308-0d34-0410-b5e6-96231b3b80d8
