2012-02-20[PCH] Recover gracefully if the ASTReader detects that a file is differentArgyrios Kyrtzidis
from the one stored in the PCH/AST, while trying to load a SLocEntry. We verify that all files of the PCH did not change before loading it but this is not enough because: - The AST may have been 1) kept around, 2) to do queries on it. - We may have 1) verified the PCH and 2) started parsing. Between 1) and 2) files may change and we are going to have crashes because the rest of clang cannot deal with the ASTReader failing to read a SLocEntry. Handle this by recovering gracefully in such a case, by initializing the SLocEntry with the info from the PCH/AST as well as reporting failure by the ASTReader. rdar://10888929 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151004 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-20Make sure that we set up the right declaration contexts when creatingDouglas Gregor
and introducing the lambda closure type and its function call operator. Previously, we assumed that the lambda closure type would land directly in the current context, and not some parent context (as occurs with linkage specifications). Thanks to Richard for the test case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150987 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-20Basic support for name mangling of C++11 lambda expressions. BecauseDouglas Gregor
name mangling in the Itanium C++ ABI for lambda expressions is so dependent on context, we encode the number used to encode each lambda as part of the lambda closure type, and maintain this value within Sema. Note that there are a several pieces still missing: - We still get the linkage of lambda expressions wrong - We aren't properly numbering or mangling lambda expressions that occur in default function arguments or in data member initializers. - We aren't (de-)serializing the lambda numbering tables git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150982 91177308-0d34-0410-b5e6-96231b3b80d8

match the behavior of GCC. Also add a test for these intrinsics, which apparently have *zero* tests. =[ Not surprisingly, Clang crashed when compiling these. Fix the bug in CodeGen where we failed to bitcast the argument type to x86mmx prior to calling the LLVM intrinsic. This fixes an assert on the new 3dnow-builtins.c test. This is one issue impacting the efforts to get Clang to emulate the Microsoft intrinsics headers -- 3dnow intrinsics are implictitly made available there. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@150948 91177308-0d34-0410-b5e6-96231b3b80d8
