I have brought LLDB up-to-date with top of tree LLVM/Clang. This brings in several fixes, including: - Improvements in the Just-In-Time compiler's allocation of memory: the JIT now allocates memory in chunks of sections, improving its ability to generate relocations. I have revamped the RecordingMemoryManager to reflect these changes, as well as to get the memory allocation and data copying out fo the ClangExpressionParser code. Jim Grosbach wrote the updates to the JIT on the LLVM side. - A new ExternalASTSource interface to allow LLDB to report accurate structure layout information to Clang. Previously we could only report the sizes of fields, not their offsets. This meant that if data structures included field alignment directives, we could not communicate the necessary alignment to Clang and accesses to the data would fail. Now we can (and I have update the relevant test case). Thanks to Doug Gregor for implementing the Clang side of this fix. - The way Objective-C interfaces are completed by Clang has been made consistent with RecordDecls; with help from Doug Gregor and Greg Clayton I have ensured that this still works. - I have eliminated all local LLVM and Clang patches, committing the ones that are still relevant to LLVM and Clang as needed. I have tested the changes extensively locally, but please let me know if they cause any trouble for you. git-svn-id: https://llvm.org/svn/llvm-project/lldb/trunk@149775 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for persistent types to the expression parser. You can use a persistent type like this: (lldb) expr struct $foo { int a; int b; }; (lldb) struct $foo i; i.a = 2; i.b = 3; i ($foo) $0 = { (int) a = 2 (int) b = 3 } typedefs work similarly. This patch affects the following files: test/expression_command/persistent_types/* A test case for persistent types, in particular structs and typedefs. ClangForward.h Added TypeDecl, needed to declare some functions in ASTResultSynthesizer.h ClangPersistentVariables.[h,cpp] Added a list of persistent types to the persistent variable store. ASTResultSynthesizer.[h,cpp] Made the AST result synthesizer iterate across TypeDecls in the expression, and record any persistent types found. Also made a minor documentation fix. ClangUserExpression.[h,cpp] Extended the user expression class to keep the state needed to report the persistent variable store for the target to the AST result synthesizers. Also introduced a new error code for expressions that executed normally but did not return a result. CommandObjectExpression.cpp Improved output for expressions (like declarations of new persistent types) that don't return a result. This is no longer treated as an error. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@138383 91177308-0d34-0410-b5e6-96231b3b80d8

Convert ValueObject to explicitly maintain the Execution Context in which they were created, and then use that when they update themselves. That means all the ValueObject evaluate me type functions that used to require a Frame object now do not. I didn't remove the SBValue API's that take this now useless frame, but I added ones that don't require the frame, and marked the SBFrame taking ones as deprecated. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@128593 91177308-0d34-0410-b5e6-96231b3b80d8

Modified LLDB expressions to not have to JIT and run code just to see variable values or persistent expression variables. Now if an expression consists of a value that is a child of a variable, or of a persistent variable only, we will create a value object for it and make a ValueObjectConstResult from it to freeze the value (for program variables only, not persistent variables) and avoid running JITed code. For everything else we still parse up and JIT code and run it in the inferior. There was also a lot of clean up in the expression code. I made the ClangExpressionVariables be stored in collections of shared pointers instead of in collections of objects. This will help stop a lot of copy constructors on these large objects and also cleans up the code considerably. The persistent clang expression variables were moved over to the Target to ensure they persist across process executions. Added the ability for lldb_private::Target objects to evaluate expressions. We want to evaluate expressions at the target level in case we aren't running yet, or we have just completed running. We still want to be able to access the persistent expression variables between runs, and also evaluate constant expressions. Added extra logging to the dynamic loader plug-in for MacOSX. ModuleList objects can now dump their contents with the UUID, arch and full paths being logged with appropriate prefix values. Thread hardened the Communication class a bit by making the connection auto_ptr member into a shared pointer member and then making a local copy of the shared pointer in each method that uses it to make sure another thread can't nuke the connection object while it is being used by another thread. Added a new file to the lldb/test/load_unload test that causes the test a.out file to link to the libd.dylib file all the time. This will allow us to test using the DYLD_LIBRARY_PATH environment variable after moving libd.dylib somewhere else. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@121745 91177308-0d34-0410-b5e6-96231b3b80d8

Made many ConstString functions inlined in the header file. Changed all of our synthesized "___clang" functions, types and variables that get used in expressions over to have a prefix of "$_lldb". Now when we do name lookups we can easily switch off of the first '$' character to know if we should look through only our internal (when first char is '$') stuff, or when we should look through program variables, functions and types. Converted all of the clang expression code over to using "const ConstString&" values for names instead of "const char *" since there were many places that were converting the "const char *" names into ConstString names and them throwing them away. We now avoid making a lot of ConstString conversions and benefit from the quick comparisons in a few extra spots. Converted a lot of code from LLVM coding conventions into LLDB coding conventions. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@116634 91177308-0d34-0410-b5e6-96231b3b80d8

First step of refactoring variable handling in the expression parser. There shouldn't be four separate classes encapsulating a variable. ClangExpressionVariable is now meant to be the container for all variable information. It has several optional components that hold data for different subsystems. ClangPersistentVariable has been removed; we now use ClangExpressionVariable instead. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@111600 91177308-0d34-0410-b5e6-96231b3b80d8

Documented ClangPersistentVariable(s). No API cleanup here, since this is a new and fairly clean class already. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@111194 91177308-0d34-0410-b5e6-96231b3b80d8

Added automatically generated result variables for each expression. It is now possible to do things like this: (lldb) expr int $i = 5; $i + 1 $0 = (int) 6 (lldb) expr $i + 3 $1 = (int) 8 (lldb) expr $1 + $0 $2 = (int) 14 As a bonus, this allowed us to move printing of expression results into the ClangPersistentVariable class. This code needs a bit of refactoring -- in particular, ClangExpressionDeclMap has eaten one too many bacteria and needs to undergo mitosis -- but the infrastructure appears to be holding up nicely. git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@110896 91177308-0d34-0410-b5e6-96231b3b80d8

Added support for persistent variables to the expression parser. It is now possible to type: (lldb) expr int $i = 5; $i + 1 (int) 6 (lldb) expr $i + 2 (int) 7 The skeleton for automatic result variables is also implemented. The changes affect: - the process, which now contains a ClangPersistentVariables object that holds persistent variables associated with it - the expression parser, which now uses the persistent variables during variable lookup - TaggedASTType, where I loaded some commonly used tags into a header so that they are interchangeable between different clients of the class git-svn-id: https://llvm.org/svn/llvm-project/llvdb/trunk@110777 91177308-0d34-0410-b5e6-96231b3b80d8
