2010-04-17Add raw_ostream operators to NamedDecl for convenience. Switch over all ↵Benjamin Kramer
users of getNameAsString on a stream. The next step is to print the name directly into the stream, avoiding a temporary std::string copy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101632 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Consolidate most of the integer constant expression builtin requirementEric Christopher
checking into a single function and use that throughout. Remove some now unnecessary diagnostics and update tests with now more accurate diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101610 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16make our existing "switch on bool" warning work for C. SinceChris Lattner
the result of comparisons are 'int' in C, it doesn't work to test just the result type of the expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101576 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-16Switch Sema::FindCompositePointerType() over to InitializationSequence. Douglas Gregor
This is the last of the uses of TryImplicitConversion outside of overload resolution and InitializationSequence itself. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101569 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-16Collapse the three separate initialization paths inDouglas Gregor
TryStaticImplicitCast (for references, class types, and everything else, respectively) into a single invocation of InitializationSequence. One of the paths (for class types) was the only client of Sema::TryInitializationByConstructor, which I have eliminated. This also simplified the interface for much of the cast-checking logic, eliminating yet more code. I've kept the representation of C++ functional casts with <> 1 arguments the same, despite the fact that I hate it. That fix will come soon. To satisfy my paranoia, I've bootstrapped + tested Clang with these changes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101549 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16Switch the checking of implicit casts for static_cast, C-style, andDouglas Gregor
functional casts over to InitializationSequence, eliminating a caller of Sema::TryImplicitConversion. We also get access and ambiguity checking "for free". More cleanups to come in this routine. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101526 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-15Audit uses of Sema::LookupSingleName for those lookups that areDouglas Gregor
intended for redeclarations, fixing those that need it. Fixes PR6831. This uncovered an issue where the C++ type-specifier-seq parsing logic would try to perform name lookup on an identifier after it already had a type-specifier, which could also lead to spurious ambiguity errors (as in PR6831, but with a different test case). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101419 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Feed proper source-location information into Sema::LookupSingleResult,Douglas Gregor

2010-04-15Fix a few cases where enum constant handling was usingDouglas Gregor
ASTContext::getTypeSize() rather than ASTContext::getIntWidth() for the width of an integral type. The former includes padding for bools (to the target's size) while the latter does not, so we woud end up zero-extending bools to the target width when we shouldn't. Fixes a crash-on-valid in the included test. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101372 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-15Warn about non-aggregate classes with no user-declared constructorsDouglas Gregor
that have reference or const scalar members, since those members can never be initializer or modified. Fixes <rdar://problem/7804350>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101316 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14Always diagnose and complain about problems inDouglas Gregor
ResolveAddressOfOverloadedFunction when asked to complain. Previously, we had some weird handshake where ResolveAddressOfOverloadedFunction expected its caller to handle some of the diagnostics but not others, and yet there was no way for the caller to know which case we were in. Eliminate this madness, fixing <rdar://problem/7765884>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101312 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14Teach typo correction about various language keywords. We can'tDouglas Gregor
generally recover from typos in keywords (since we would effectively have to mangle the token stream). However, there are still benefits to typo-correcting with keywords: - We don't make stupid suggestions when the user typed something that is similar to a keyword. - We can suggest the keyword in a diagnostic (did you mean "static_cast"?), even if we can't recover and therefore don't have a fix-it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101274 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14Return the corrected DeclarationName from Sema::CorrectTypo ratherDouglas Gregor
than just a bool indicating that correction occurred. No actual functionality change (it's still always used like a bool), but this refactoring will be used to support typo correction to keywords. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101259 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-14When diagnosing suspicious precedence or assignments, move the fix-itDouglas Gregor
that adds parentheses from the main diagnostic down to a new note. This way, when the fix-it represents a choice between two options, each of the options is associted with a note. There is no default option in such cases. For example: /Users/dgregor/t.c:2:9: warning: & has lower precedence than ==; == will be evaluated first [-Wparentheses] if (x & y == 0) { ^~~~~~~~ /Users/dgregor/t.c:2:9: note: place parentheses around the & expression to evaluate it first if (x & y == 0) { ^ ( ) /Users/dgregor/t.c:2:9: note: place parentheses around the == expression to silence this warning if (x & y == 0) { ^ ( ) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101249 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14Implement typo correction for Objective-C message sends when theDouglas Gregor
receiver is a mis-typed class name. Previously, we would give a non-specific typo-correction diagnostic from the expression-parsing code, but there was no fix-it because it was too late to recover. Now, we give a nice diagnostic honk.m:6:4: error: unknown receiver 'Hnk'; did you mean 'Honk'? [Hnk method]; ^~~ Honk honk.m:1:1: note: 'Honk' declared here @interface Honk ^ which includes a fix-it. We still need to recover better from mis-typing "super". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101211 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Refactor and simplify the computation of implicit conversion sequencesDouglas Gregor
for reference binding. The code attempted to handle both the computation of the ICS and the actual conversion, but the latter is an anachronism: we now use InitializationSequence for that. Sema::CheckReferenceInit is now a static function TryReferenceInit that's only use within overload resolution, and has been simplified slightly. It still needs to be updated per C++ [over.ics.ref], by eliminating more of the lvalue/rvalue checks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101136 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12Implement C++ [over.ics.user]p3, which restricts the final conversionDouglas Gregor
from a conversion function template specialization to one of exact match rank. We only know how to test this in C++0x with default function template arguments, but it's also in the C++03 spec. Fixes PR6285. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101089 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Improve source-location information for C++ conversion functions, byDouglas Gregor
copying the type location information from the conversion-type-id into the type location information for the function type. Do something similar for constructors and destructors, by giving their "void" return type source-location information. In all of these cases, we previously left this type-source information uninitialized, which led to various unfortunate crashes. We still aren't tracking good source-location information for the actual names. That's PR6357. John, please check my sanity on this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@101088 91177308-0d34-0410-b5e6-96231b3b80d8
