2012-10-02Add FP_CONTRACT support for clang.Lang Hames
Clang will now honor the FP_CONTRACT pragma and emit LLVM fmuladd intrinsics for expressions of the form A * B + C (when they occur in a single statement). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164989 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-02-Wformat: Don't check format strings in uninstantiated templates.Jordan Rose
Also applies to -Wnonnull, -Wtype-safety, and -Wnon-pod-varargs. All of these can be better checked at instantiation time. This change does not actually affect regular CallExpr function calls, since the checks there only happen after overload resolution. However, it will affect Objective-C method calls. <rdar://problem/12373934> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164984 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-01[analyzer] Allow ObjC ivar lvalues where the base is nil.Jordan Rose
By analogy with C structs, this seems to be legal, if probably discouraged. It's only if the ivar is read from or written to that there's a problem. Running a program that gets the "address" of an instance variable does in fact return the offset when the base "object" is nil. This isn't a full revert because r164442 includes some diagnostic tweaks as well; those have been kept. This partially reverts r164442 / 08965091770c9b276c238bac2f716eaa4da2dca4. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164960 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-01[analyzer] Add a test for PR13927 "offsetof replacement flagged as null deref"Jordan Rose

2012-10-01Revert "[analyzer] Check that a member expr is valid even when the result is ↵Jordan Rose
an lvalue." The original intent of this commit was to catch potential null dereferences early, but it breaks the common "home-grown offsetof" idiom (PR13927): (((struct Foo *)0)->member - ((struct foo *)0)) As it turns out, this appears to be legal in C, per a footnote in C11 6.5.3.2: "Thus, &*E is equivalent to E (even if E is a null pointer)". In C++ this issue is still open: http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_active.html#232 We'll just have to make sure we have good path notes in the future. This reverts r164441 / 9be016dcd1ca3986873a7b66bd4bc027309ceb59. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164958 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-01The Redeclarable part of named decls is read before their name.Axel Naumann
Lookup can nevertheless find them due to the serialized lookup table. For instance when reading a template decl's templatedDecl, it will search for existing decls that it could be a redeclaration of, and find the half-read template decl. Thus there is no point in asserting the names of decls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@164932 91177308-0d34-0410-b5e6-96231b3b80d8
