* Removed many JIT workarounds from IRForTarget.Sean Callanan2016-02-131-19/+0
| | | | | | | | | | | | | | | | | | | | | | Since IRExecutionUnit is now capable of looking up symbols, and the JIT is up to the task of generating the appropriate relocations, we don't need to do all the work that IRForTarget used to do to fixup symbols at the IR level. We also don't need to allocate data manually (with its attendant bugs) because the JIT is capable of doing so without crashing. We also don't need the awkward lldb.call.realName metadata to determine what calls are objc_msgSend, because they now just reference objc_msgSend. To make this work, we ensure that we recognize which symbols are extern "C" and report them to the compiler as such. We also report the full Decl of functions rather than just making up top-level functions with the appropriate types. This should not break any testcases, but let me know if you run into any issues. <rdar://problem/22864926> llvm-svn: 260768

* Use an artifical namespace so that member vars do not hide local vars.Siva Chandra2016-02-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: While evaluating expressions when stopped in a class method, there was a problem of member variables hiding local variables. This was happening because, in the context of a method, clang already knew about member variables with their name and assumed that they were the only variables with those names in scope. Consequently, clang never checks with LLDB about the possibility of local variables with the same name and goes wrong. This change addresses the problem by using an artificial namespace "$__lldb_local_vars". All local variables in scope are declared in the "$__lldb_expr" method as follows: using $__lldb_local_vars::<local var 1>; using $__lldb_local_vars::<local var 2>; ... This hides the member variables with the same name and forces clang to enquire about the variables which it thinks are declared in $__lldb_local_vars. When LLDB notices that clang is enquiring about variables in $__lldb_local_vars, it looks up local vars and conveys their information if found. This way, member variables do not hide local variables, leading to correct evaluation of expressions. A point to keep in mind is that the above solution does not solve the problem for one specific case: namespace N { int a; } class A { public: void Method(); int a; }; void A::Method() { using N::a; ... // Since the above solution only touches locals, it does not // force clang to enquire about "a" coming from namespace N. } Reviewers: clayborg, spyffe Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D16746 llvm-svn: 259810

* Add PersistentVariableDelegate to handle language-specific dematerialization.Sean Callanan2015-10-031-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | The concept here is that languages may have different ways of communicating results. In particular, languages may have different names for their result variables and in fact may have multiple types of result variables (e.g., error results). Materializer was tied to one specific model of result handling. Instead, now UserExpressions can register their own handlers for the result variables they inject. This allows language-specific code in Materializer to be moved into the expression parser plug-in, and it simplifies Materializer. These delegates are subclasses of PersistentVariableDelegate. PersistentVariableDelegate can provide the name of the result variable, and is notified when the result variable is populated. It can also be used to touch persistent variables if need be, updating language-specific state. The UserExpression owns the delegate and can decide on its result based on consulting all of its (potentially multiple) delegates. The user expression itself now makes the determination of what the final result of the expression is, rather than relying on the Materializer, and I've added a virtual function to UserExpression to allow this. llvm-svn: 249233
* Moved more Clang-specific parts of the expression parser into the Clang plugin.Sean Callanan2015-09-251-0/+705
There are still a bunch of dependencies on the plug-in, but this helps to identify them. There are also a few more bits we need to move (and abstract, for example the ClangPersistentVariables). llvm-svn: 248612
