2013-02-22Only suppress instance context if a member is actuallyJohn McCall
accessible in its declaring class; otherwise we might fail to apply [class.protected] when considering accessibility in derived classes. Noticed by inspection; <rdar://13270329>. I had an existing test wrong. Here's why it's wrong: Follow the rules (and notation) of [class.access]p5. The naming class (N) is B and the context (R) is D::getX. - 'x' as a member of B is protected, but R does not occur in a member or friend of a class derived from B. - There does exist a base class of B, A, which is accessible from R, and 'x' is accessible at R when named in A because 'x' as a member of A is protected and R occurs in a member of a class, D, that is derived from A; however, by [class.protected], the class of the object expression must be equal to or derived from that class, and A does not derive from D. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175858 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22[analyzer] Place all inlining policy checks into one palceAnna Zaks
Previously, we had the decisions about inlining spread out over multiple functions. In addition to the refactor, this commit ensures that we will always inline BodyFarm functions as long as the Decl is available. This fixes false positives due to those functions not being inlined when no or minimal inlining is enabled such (as shallow mode). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175857 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22Add -fbracket-depth=N, analogous to -ftemplate-depth= and -fconstexpr-depth=,Richard Smith
to control the check for the C 5.2.4.1 / C++ [implimits] restriction on nesting levels for parentheses, brackets and braces. Some code with heavy macro use exceeds the default limit of 256, but we don't want to increase it generally to avoid stack overflow on stack-constrained systems. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175855 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22[analyzer] Make sure a materialized temporary matches its bindings.Jordan Rose
This is a follow-up to r175830, which made sure a temporary object region created for, say, a struct rvalue matched up with the initial bindings being stored into it. This does the same for the case in which the AST actually tells us that we need to create a temporary via a MaterializeObjectExpr. I've unified the two code paths and moved a static helper function onto ExprEngine. This also caused a bit of test churn, causing us to go back to describing temporary regions without a 'const' qualifier. This seems acceptable; it's our behavior from a few months ago. <rdar://problem/13265460> (part 2) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175854 91177308-0d34-0410-b5e6-96231b3b80d8

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

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
