* UtilityFunction::MakeFunctionCaller uses the Error to report failure,Jim Ingham2016-04-261-0/+3

* Compilation can end up calling functions (e.g. to resolve indirect ↵Jim Ingham2016-03-211-2/+2

* Add a DiagnosticManager replace error streams in the expression parser.Sean Callanan2016-03-191-15/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We want to do a better job presenting errors that occur when evaluating expressions. Key to this effort is getting away from a model where all errors are spat out onto a stream where the client has to take or leave all of them. To this end, this patch adds a new class, DiagnosticManager, which contains errors produced by the compiler or by LLDB as an expression is created. The DiagnosticManager can dump itself to a log as well as to a string. Clients will (in the future) be able to filter out the errors they're interested in by ID or present subsets of these errors to the user. This patch is not intended to change the *users* of errors - only to thread DiagnosticManagers to all the places where streams are used. I also attempt to standardize our use of errors a bit, removing trailing newlines and making clients omit 'error:', 'warning:' etc. and instead pass the Severity flag. The patch is testsuite-neutral, with modifications to one part of the MI tests because it relied on "error: error:" being erroneously printed. This patch fixes the MI variable handling and the testcase. <rdar://problem/22864976> llvm-svn: 263859

* This patch makes Clang-independent base classes for all the expression types ↵Jim Ingham2015-09-151-0/+123
that lldb currently vends. Before we had: ClangFunction ClangUtilityFunction ClangUserExpression and code all over in lldb that explicitly made Clang-based expressions. This patch adds an Expression base class, and three pure virtual implementations for the Expression kinds: FunctionCaller UtilityFunction UserExpression You can request one of these expression types from the Target using the Get<ExpressionType>ForLanguage. The Target will then consult all the registered TypeSystem plugins, and if the type system that matches the language can make an expression of that kind, it will do so and return it. Because all of the real expression types need to communicate with their ExpressionParser in a uniform way, I also added a ExpressionTypeSystemHelper class that expressions generically can vend, and a ClangExpressionHelper that encapsulates the operations that the ClangExpressionParser needs to perform on the ClangExpression types. Then each of the Clang* expression kinds constructs the appropriate helper to do what it needs. The patch also fixes a wart in the UtilityFunction that to use it you had to create a parallel FunctionCaller to actually call the function made by the UtilityFunction. Now the UtilityFunction can be asked to vend a FunctionCaller that will run its function. This cleaned up a lot of boiler plate code using UtilityFunctions. Note, in this patch all the expression types explicitly depend on the LLVM JIT and IR, and all the common JIT running code is in the FunctionCaller etc base classes. At some point we could also abstract that dependency but I don't see us adding another back end in the near term, so I'll leave that exercise till it is actually necessary. llvm-svn: 247720
