2012-10-18PR14021: Copy lookup results to ensure safe iteration.David Blaikie
Within the body of the loop the underlying map may be modified via Sema::AddOverloadCandidate -> Sema::CompareReferenceRelationship -> Sema::RequireCompleteType to avoid the use of invalid iterators the sequence is copied first. A reliable, though large, test case is available - it will be reduced and committed shortly. Patch by Robert Muth.

2012-10-18Start factoring the on-disk records for an AST file into a controlDouglas Gregor
block, which stores information about how the AST file to generated, from the AST block, which stores the actual serialized AST. The information in the control block should be enough to determine whether the AST file is up-to-date and compatible with the current translation unit, and reading it should not cause any side effects that aren't easy to undo. That way, we can back out from an attempt to read an incompatible or out-of-date AST file. Note that there is still more factoring to do. In particular, information about the source files used to generate the AST file (along with their time stamps, sizes, etc.) still resides in the source manager block. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166166 91177308-0d34-0410-b5e6-96231b3b80d8

declaration of a virtual function. GCC and Clang both do not warn on: struct a { virtual void func(); }; struct b: a { virtual void func(); void func(int); }; struct c: b { void func(int); using b::func; }; but if the "using" was using a::func GCC would still remain silent where Clang would warn.

2012-10-17[analyzer] When binding to a ParenExpr, bind to its inner expression instead.Jordan Rose
This actually looks through several kinds of expression, such as OpaqueValueExpr and ExprWithCleanups. The idea is that binding and lookup should be consistent, and so if the environment needs to be modified later, the code doing the modification will not have to manually look through these "transparent" expressions to find the real binding to change. This is necessary for proper updating of struct rvalues as described in the previous commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166121 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-17[analyzer] Create a temporary region when accessing a struct rvalue.Jordan Rose
In C++, rvalues that need to have their address taken (for example, to be passed to a function by const reference) will be wrapped in a MaterializeTemporaryExpr, which lets CodeGen know to create a temporary region to store this value. However, MaterializeTemporaryExprs are /not/ created when a method is called on an rvalue struct, even though the 'this' pointer needs a valid value. CodeGen works around this by creating a temporary region anyway; now, so does the analyzer. The analyzer also does this when accessing a field of a struct rvalue. This is a little unfortunate, since the rest of the struct will soon be thrown away, but it does make things consistent with the rest of the analyzer. This allows us to bring back the assumption that all known 'this' values are Locs. This is a revised version of r164828-9, reverted in r164876-7. <rdar://problem/12137950> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166120 91177308-0d34-0410-b5e6-96231b3b80d8

combination of a load+objc_release; this is generally better for tools that try to track why values are retained and released.

2012-10-16Add pnaclcall convention to Native Client targets.Derek Schuff
Because PNaCl bitcode must be target-independent, it uses some different bitcode representations from other targets (e.g. byval and sret for structures). This means that without additional type information, it cannot meet some native ABI requirements for some targets (e.g. passing structures containing unions by value on x86-64). To allow generation of code which uses the correct native ABIs, we also support triples such as x86_64-nacl, which uses target-dependent IR (as opposed to le32-nacl, which uses byval and sret). To allow interoperation between the two types of code, this patch adds a calling convention attribute to be used in code compiled with the target-dependent triple, which will generate code using the le32-style bitcode. This calling convention does not need to be explicitly supported in the backend because it determines bitcode representation rather than native conventions (the backend just needs to undersand how to handle byval and sret for the Native Client OS). This patch implements __attribute__((pnaclcall)) to generate calls in bitcode according to the le32 bitcode conventions, an attribute which is accepted by any Native Client target, but issues a warning otherwise. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166065 91177308-0d34-0410-b5e6-96231b3b80d8
