2013-02-28Use the actual ABI-determined C calling convention for runtimeJohn McCall
calls and declarations. LLVM has a default CC determined by the target triple. This is not always the actual default CC for the ABI we've been asked to target, and so we sometimes find ourselves annotating all user functions with an explicit calling convention. Since these calling conventions usually agree for the simple set of argument types passed to most runtime functions, using the LLVM-default CC in principle has no effect. However, the LLVM optimizer goes into histrionics if it sees this kind of formal CC mismatch, since it has no concept of CC compatibility. Therefore, if this module happens to define the "runtime" function, or got LTO'ed with such a definition, we can miscompile; so it's quite important to get this right. Defining runtime functions locally is quite common in embedded applications. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176286 91177308-0d34-0410-b5e6-96231b3b80d8

This does not yet implement the LimitNode approach discussed.

2013-02-27[analyzer] Teach FindLastStoreBRVisitor to understand stores of the same value.Jordan Rose
Consider this case: int *p = 0; p = getPointerThatMayBeNull(); *p = 1; If we inline 'getPointerThatMayBeNull', we might know that the value of 'p' is NULL, and thus emit a null pointer dereference report. However, we usually want to suppress such warnings as error paths, and we do so by using FindLastStoreBRVisitor to see where the NULL came from. In this case, though, because 'p' was NULL both before and after the assignment, the visitor would decide that the "last store" was the initialization, not the re-assignment. This commit changes FindLastStoreBRVisitor to consider all PostStore nodes that assign to this region. This still won't catches changes made directly by checkers if they re-assign the same value, but it does handle the common case in user-written code and will trigger ReturnVisitor's suppression machinery as expected. <rdar://problem/13299738> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176201 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-27Don't cache the visibility of types.Rafael Espindola
Since r175326 an implicitly hidden template argument can cause a template installation to become hidden, even if the template itself has an explicit default visibility. This requires that we keep track of "late" additions of the visibility attribute. This is hopefully the last followup change. It just removes the caching of visibilities from types so that we can see new attributes even after a type has been used. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176164 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-27[analyzer] If a struct has a partial lazy binding, its fields aren't Undef.Jordan Rose
This is essentially the same problem as r174031: a lazy binding for the first field of a struct may stomp on an existing default binding for the entire struct. Because of the way RegionStore is set up, we can't help but lose the top-level binding, but then we need to make sure that accessing one of the other fields doesn't come back as Undefined. In this case, RegionStore is now correctly detecting that the lazy binding we have isn't the right type, but then failing to follow through on the implications of that: we don't know anything about the other fields in the aggregate. This fix adds a test when searching for other kinds of default values to see if there's a lazy binding we rejected, and if so returns a symbolic value instead of Undefined. The long-term fix for this is probably a new Store model; see <rdar://problem/12701038>. Fixes <rdar://problem/13292559>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176144 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-27Refine SourceManager's isBeforeInTranslationUnit() cache to have more entries.Ted Kremenek
isBeforeInTranslationUnit() uses a cache to reduce the expensive work to compute a common ancestor for two FileIDs. This work is very expensive, so even caching the latest used FileIDs was a big win. A closer analysis of the cache before, however, shows that the cache access pattern would oscillate between a working set of FileIDs, and thus caching more pairs would be profitable. This patch adds a side table for extending caching. This side table is bounded in size (experimentally determined in this case from a simple Objective-C project), and when the table gets too large we fall back to the single entry caching before as before. On Sketch (a small example Objective-C project), this optimization reduces -fsyntax-only time on SKTGraphicView.m by 5%. This is for a project that is already using PCH.
