2011-04-07Basic, untested implementation for an "unknown any" type requested by LLDB.John McCall
The idea is that you can create a VarDecl with an unknown type, or a FunctionDecl with an unknown return type, and it will still be valid to access that object as long as you explicitly cast it at every use. I'm still going back and forth about how I want to test this effectively, but I wanted to go ahead and provide a skeletal implementation for the LLDB folks' benefit and because it also improves some diagnostic goodness for placeholder expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129065 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-05Commit a bit of a hack to fully handle the situation where variables areChandler Carruth
marked explicitly as uninitialized through direct self initialization: int x = x; With r128894 we prevented warnings about this code, and this patch teaches the analysis engine to continue analyzing subsequent uses of 'x'. This should wrap up PR9624. There is still an open question of whether we should suppress the maybe-uninitialized warnings resulting from variables initialized in this fashion. The definitely-uninitialized uses should always be warned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128932 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-05Added *hidden* flags -print-options and -print-all-options soAndrew Trick
developers can see if their driver changed any cl::Option's. The current implementation isn't perfect but handles most kinds of options. This is nice to have when decomposing the stages of compilation and moving between different drivers. It's also a good sanity check when comparing results produced by different command line invocations that are expected to produce the comparable results. Note: This is not an attempt to prolong the life of cl::Option. On the contrary, it's a placeholder for a feature that must exist when cl::Option is replaced by a more appropriate framework. A new framework needs: a central option registry, dynamic name lookup, non-global containers of option values (e.g. per-module, per-function), *and* the ability to print options values and their defaults at any point during compilation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128911 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-05Separate the logic for issuing the initialization fixit hint from theChandler Carruth
diagnostic emission. The fixit hint, when suggested, typically has nothing to do with the nature or form of the reference. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128899 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-05Begin refactoring the uninitialized warning code that I uglied up. ThisChandler Carruth
extracts a function to handle the emission of the diagnostic separately from the walking over the set of uninitialized uses. Also updates the naming used within this extracted function to be a bit more consistent with the rest of Clang's naming patterns. The next step will be breaking this apart so that we can go through different functions rather than tracking so many boolean variables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128898 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-05Fix PR9624 by explicitly disabling uninitialized warnings for direct self-init:Chandler Carruth
int x = x; GCC disables its warnings on this construct as a way of indicating that the programmer intentionally wants the variable to be uninitialized. Only the warning on the initializer is turned off in this iteration. This makes the code a lot more ugly, but starts commenting the surprising behavior here. This is a WIP, I want to refactor it substantially for clarity, and to determine whether subsequent warnings should be suppressed or not. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128894 91177308-0d34-0410-b5e6-96231b3b80d8

numerous CFG and UninitializedValues analysis changes: 1) Change the CFG to include the DeclStmt for conditional variables, instead of using the condition itself as a faux DeclStmt. 2) Update ExprEngine (the static analyzer) to understand (1), so not to regress. 3) Update UninitializedValues.cpp to initialize all tracked variables to Uninitialized at the start of the function/method. 4) Only use the SelfReferenceChecker (SemaDecl.cpp) on global variables, leaving the dataflow analysis to handle other cases. The combination of (1) and (3) allows the dataflow-based -Wuninitialized to find self-init problems when the initializer contained control-flow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128858 91177308-0d34-0410-b5e6-96231b3b80d8
