2012-04-07Fix several problems with protected access control:John McCall
- The [class.protected] restriction is non-trivial for any instance member, even if the access lacks an object (for example, if it's a pointer-to-member constant). In this case, it is equivalent to requiring the naming class to equal the context class. - The [class.protected] restriction applies to accesses to constructors and destructors. A protected constructor or destructor can only be used to create or destroy a base subobject, as a direct result. - Several places were dropping or misapplying object information. The standard could really be much clearer about what the object type is supposed to be in some of these accesses. Usually it's easy enough to find a reasonable answer, but still, the standard makes a very confident statement about accesses to instance members only being possible in either pointer-to-member literals or member access expressions, which just completely ignores concepts like constructor and destructor calls, using declarations, unevaluated field references, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154248 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-06Remove "parse error" in favor of more descriptive diagnostics.David Blaikie
In a few cases clang emitted a rather content-free diagnostic: 'parse error'. This change replaces two actual cases (template parameter parsing and K&R parameter declaration parsing) with more specific diagnostics and removes a third dead case of this in the BalancedDelimiterTracker (the ctor already checked the invariant necessary to ensure that the diag::parse_error was never actually used). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154224 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-06Rework ExprEngine::evalLoad and clients (e.g. VisitBinaryOperator) so that ↵Ted Kremenek
when we generate a new ExplodedNode we use the same Expr* as the one being currently visited. This is preparation for transitioning to having ProgramPoints refer to CFGStmts. This required a bit of trickery. We wish to keep the old Expr* bindings in the Environment intact, as plenty of logic relies on it and there is no reason to change it, but we sometimes want the Stmt* for the ProgramPoint to be different than the Expr* being used for bindings. This requires adding an extra argument for some functions (e.g., evalLocation). This looks a bit strange for some clients, but it will look a lot cleaner when were start using CFGStmt* in the appropriate places. As some fallout, the diagnostics arrows are a bit difference, since some of the node locations have changed. I have audited these, and they look reasonable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154214 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-06SourceManager: Vectorize ComputeLineNumbers for SSE2.Benjamin Kramer
This method is very hot, it is called when emitting diagnostics, in -E mode and for many #pragma handlers. It scans through the whole source file to count newlines, records and caches them in a vector. The speedup from vectorization isn't very large, as we fall back to bytewise scanning when we hit a newline. There might be a way to avoid leaving the sse loop but everything I tried didn't work out because a call to push_back clobbers xmm registers. About 2% speedup on average on "clang -E > /dev/null" of all .cpp files in clang's lib/Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154204 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-06Fix using Clang as a cross compiler installed on a host machine and notChandler Carruth
inside of a sysroot targeting a system+sysroot which is "similar" or "compatible" with the host system. This shows up when trying to build system images on largely compatible hardware as-if fully cross compiled. The problem is that previously we *perfectly* mimiced GCC here, and it turns out GCC has a bug that no one has really stumbled across. GCC will try to look in thy system prefix ('/usr/local' f.ex.) into which it is instaled to find libraries installed along side GCC that should be preferred to the base system libraries ('/usr' f.ex.). This seems not unreasonable, but it has a very unfortunate consequence when combined with a '--sysroot' which does *not* contain the GCC installation we're using to complete the toolchain. That results in some of the host system's library directories being searched during the link. Now, it so happens that most folks doing stuff like this use '--with-sysroot' and '--disable-multilib' when configuring GCC. Even better, they're usually not cross-compiling to a target that is similar to the host. As a result, searching the host for libraries doesn't really matter -- most of the time weird directories get appended that don't exist (no arm triple lib directory, etc). Even if you're cross-compiling from 32-bit to 64-bit x86 or vice-versa, disabling multilib makes it less likely that you'll actually find viable libraries on the host. But that's just luck. We shouldn't rely on this, and this patch disables looking in the system prefix containing the GCC installation if that system prefix is *outside* of the sysroot. For empty sysroots, this has no effect. Similarly, when using the GCC *inside* of the sysroot, we still track wherever it is installed within the sysroot and look there for libraries. But now we can use a cross compiler GCC installation outside the system root, and only look for the crtbegin.o in the GCC installation, and look for all the other libraries inside the system root. This should fix PR12478, allowing Clang to be used when building a ChromiumOS image without polluting the image with libraries from the host system. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@154176 91177308-0d34-0410-b5e6-96231b3b80d8
