2012-08-30Fix a crash in type merging with enum types.Eli Friedman
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162886 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-29Move TLS check from LValueExprEvaluator::VisitVarDecl toHans Wennborg
CheckLValueConstantExpression. Richard pointed out that using the address of a TLS variable is ok in a core C++11 constant expression, as long as it isn't part of the eventual result of constant expression evaluation. Having the check in CheckLValueConstantExpression accomplishes this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162850 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-29Fix r162835 as per Richard's comments.Hans Wennborg
VisitVarDecl should return Error(E), and we should test that the address of a TLS var can't be used as a constexpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162837 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-29The address of a TLS var is not compile-time constant (PR13720)Hans Wennborg
This makes Clang produce an error for code such as: __thread int x; int *p = &x; The lvalue of a thread-local variable cannot be evaluated at compile time. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162835 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28[ms-inline asm] Have generateAsmString() return the AsmString computed by Sema.Chad Rosier
We still need to translate the string, but this at least gets us one step closer to using the more general EmitAsmStmt() codegen function. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162785 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-28[ms-inline asm] Add constraints to MSAsmStmt. We don't currently computeChad Rosier

2012-08-23Attaching comments to decls: since it was decided that Decl::isImplicit shouldDmitri Gribenko
not be set for implicit instantiations, remove the FIXME. This should be the last bit for PR13634. The actual fix happened in r162238. Motivation: it might be misleading to mark implicit instantiations as Decl::isImplicit = true. Because then, in order to be consistent, we should mark all instantiated members as implicit. But the user did actually type the declaration for the member, but the compiler played with it a little bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162488 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-23Change a bunch of cases where we do "getAs<...>->doSomething()" toTed Kremenek
"castAs<...>->doSomething()". The analyzer was flagging these as potential null dereferences, which is technically true. The invariants appear to be that these casts should never fail, so let's use castAs<> instead and avoid a runtime check. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162468 91177308-0d34-0410-b5e6-96231b3b80d8

name. This should reduce the amount of warning false positives about bad HTML in comments when the comment author intended to put a reference to a template. This change will also enable us parse the comment as intended in these cases.

to overwrite objects that might have been allocated into the type's tail padding. This patch is missing some potential optimizations where the destination is provably a complete object, but it's necessary for correctness. Patch by Jonathan Sauer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162254 91177308-0d34-0410-b5e6-96231b3b80d8
2012-08-20DeclPrinter: add terse output mode and lots of testsDmitri Gribenko
Add a flag PrintingPolicy::DontRecurseInDeclContext to provide "terse" output from DeclPrinter. The motivation is to use DeclPrinter to print declarations in user-friendly format, without overwhelming user with inner detail of the declaration being printed. Also add many tests for DeclPrinter. There are quite a few things that we print incorrectly: search for WRONG in DeclPrinterTest.cpp -- and these tests check our output against incorrect output, so that we can fix/refactor/rewrite the DeclPrinter later. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@162245 91177308-0d34-0410-b5e6-96231b3b80d8

and remove ASTContext reference (which was frequently bound to a dereferenced null pointer) from the recursive lump of printPretty functions.

This is the other half of C++11 [class.cdtor]p4 (the destructor side was added in r161915).
