2013-03-23Revert svn r176894 and r177658.Bob Wilson
Changing -ccc-install-dir to affect cc1's resource-dir setting broke our internal LNT tests. After discussing the situation with Jim, we've decided to pursue an alternate approach. We really want the resource-dir to be located relative to clang, even when using -ccc-install-dir, but we're going to add a fallback setting for the libc++ headers if they don't exist alongside the compiler. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177815 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-23[analyzer] Teach constraint managers about unsigned comparisons.Jordan Rose
In C, comparisons between signed and unsigned numbers are always done in unsigned-space. Thus, we should know that "i >= 0U" is always true, even if 'i' is signed. Similarly, "u >= 0" is also always true, even though '0' is signed. Part of <rdar://problem/13239003> (false positives related to std::vector) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177806 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-23[analyzer] Also transform "a < b" to "(b - a) > 0" in the constraint manager.Jordan Rose
We can support the full range of comparison operations between two locations by canonicalizing them as subtraction, as in the previous commit. This won't work (well) if either location includes an offset, or (again) if the comparisons are not consistent about which region comes first. <rdar://problem/13239003> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177803 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-23[analyzer] Translate "a != b" to "(b - a) != 0" in the constraint manager.Jordan Rose
Canonicalizing these two forms allows us to better model containers like std::vector, which use "m_start != m_finish" to implement empty() but "m_finish - m_start" to implement size(). The analyzer should have a consistent interpretation of these two symbolic expressions, even though it's not properly reasoning about either one yet. The other unfortunate thing is that while the size() expression will only ever be written "m_finish - m_start", the comparison may be written "m_finish == m_start" or "m_start == m_finish". Right now the analyzer does not attempt to canonicalize those two expressions, since it doesn't know which length expression to pick. Doing this correctly will probably require implementing unary minus as a new SymExpr kind (<rdar://problem/12351075>). For now, the analyzer inverts the order of arguments in the comparison to build the subtraction, on the assumption that "begin() != end()" is written more often than "end() != begin()". This is purely speculation. <rdar://problem/13239003> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177801 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-23[analyzer] Use SymExprs to represent '<loc> - <loc>' and '<loc> == <loc>'.Jordan Rose
We just treat this as opaque symbols, but even that allows us to handle simple cases where the same condition is tested twice. This is very common in the STL, which means that any project using the STL gets spurious errors. Part of <rdar://problem/13239003>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@177800 91177308-0d34-0410-b5e6-96231b3b80d8

2013-03-23If a .syms file is available alongside a sanitizer runtime, pass it to theRichard Smith

2013-03-22Use RequireCompleteType() instead of isIncompleteType().Bill Wendling
isIncompleteType() returns true or false for template types depending on whether the type is instantiated yet. In this context, that's arbitrary. The better way to check for a complete type is RequireCompleteType().

2013-03-22[ms-cxxabi] Implement member data pointers for non-dynamic classesReid Kleckner
Summary: For non-dynamic classes (no virtual bases), member data pointers are simple offsets from the base of the record. Dynamic classes use an aggregate for member data pointers and are therefore currently unsupported. Unlike Itanium, the ms ABI uses 0 to represent null for polymorphic classes. Non-polymorphic classes use -1 like Itanium, since 0 is a valid field offset.

headers defining size_t/ptrdiff_t/wchar_t. Clang's <stddef.h> provides definitions for the C standard library types size_t, ptrdiff_t, and wchar_t. However, the system's C standard library headers tend to provide the same typedefs, and the two generally avoid each other using the macros _SIZE_T/_PTRDIFF_T/_WCHAR_T.
