2013-02-07Fix handling of module imports adding names to a DeclContext after qualifiedRichard Smith
name lookup has been performed in that context (this probably only happens in C++). 1) Whenever we add names to a context, set a flag on it, and if we perform lookup and discover that the context has had a lookup table built but has the flag set, update all entries in the lookup table with additional names from the external source. 2) When marking a DeclContext as having external visible decls, mark the context in which lookup is performed, not the one we are adding. These won't be the same if we're adding another copy of a pre-existing namespace. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174577 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07Simplify FindExternalVisibleDeclsByName by making it return a bool indicatingRichard Smith
if it found any decls, rather than returning a list of found decls. This removes a returning-ArrayRef-to-deleted-storage bug from MultiplexExternalSemaSource (in code not exercised by any of the clang binaries), reduces the work required in the found-no-decls case with PCH, and importantly removes the need for DeclContext::lookup to be reentrant. No functionality change intended! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174576 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-07-Wimplicit-fallthrough: fixed two cases where "fallthrough annotation in ↵Alexander Kornienko

In actual unreachable code, but not immediately on a fall-through execution path "fallthrough annotation does not directly precede switch label" is better; 2. After default: in a switch with covered enum cases. Actually, these shouldn't be treated as unreachable code for our purpose.

2013-02-07Introduce -fmodules-ignore-macro=NNN to ignore a macro when building/loading ↵Douglas Gregor
modules. The use of this flag enables a modules optimization where a given set of macros can be labeled as "ignored" by the modules system. Definitions of those macros will be completely ignored when building the module hash and will be stripped when actually building modules. The overall effect is that this flag can be used to drastically reduce the number of Eventually, we'll want modules to tell us what set of macros they respond to (the "configuration macros"), and anything not in that set will be excluded.

2013-02-06[analyzer]Revert part of r161511; suppresses leak false positives in C++Anna Zaks
This is a "quick fix". The underlining issue is that when a const pointer to a struct is passed into a function, we do not invalidate the pointer fields. This results in false positives that are common in C++ (since copy constructors are prevalent). (Silences two llvm false positives.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174468 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-05Change subexpressions to be visited in the CFG from left-to-right.Ted Kremenek
This is a more natural order of evaluation, and it is very important for visualization in the static analyzer. Within Xcode, the arrows will not jump from right to left, which looks very visually jarring. It also provides a more natural location for dataflow-based diagnostics. Along the way, we found a case in the analyzer diagnostics where we needed to indicate that a variable was "captured" by a block. -fsyntax-only timings on sqlite3.c show no visible performance change, although this is just one test case.
