2013-02-22Preproceessor: fix #if skipping under -traditional-cpp.Jordan Rose
When parsing directives within skipped #if blocks, we don't want to retain any whitespace. Previously we were just skipping comments, but it's not possible to skip comments and retain other whitespace. This change matches the usual behavior for parsing directives (i.e. the behavior outside of skipped #if blocks). <rdar://problem/13267695> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175840 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-21[analyzer] Make sure a temporary object region matches its initial bindings.Jordan Rose
When creating a temporary region (say, when a struct rvalue is used as the base of a member expr), make sure we account for any derived-to-base casts. We don't actually record these in the LazyCompoundVal that represents the rvalue, but we need to make sure that the temporary region we're creating (a) matches the bindings, and (b) matches its expression. Most of the time this will do exactly the same thing as before, but it fixes spurious "garbage value" warnings introduced in r175234 by the use of lazy bindings to model trivial copy constructors. <rdar://problem/13265460> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175830 91177308-0d34-0410-b5e6-96231b3b80d8

being included in C++. Don't define alignof or alignas in this case.

2013-02-21[analyzer] Tighten up safety in the use of lazy bindings.Jordan Rose
- When deciding if we can reuse a lazy binding, make sure to check if there are additional bindings in the sub-region. - When reading from a lazy binding, don't accidentally strip off casts or base object regions. This slows down lazy binding reading a bit but is necessary for type sanity when treating one class as another. A bit of minor refactoring allowed these two checks to be unified in a nice early-return-using helper function. <rdar://problem/13239840> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175703 91177308-0d34-0410-b5e6-96231b3b80d8
