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.

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

made IR-based expression evaluation the default.
Also added a new class to hold persistent variables.
The class is empty as yet while I write up a design
document for what it will do. Also the place where
it is currently created (by the Expression command)
is certainly wrong.

including superclass members. This involved ensuring
that access control was ignored, and ensuring that
the operands of BitCasts were properly scanned for
variables that needed importing.
Also laid the groundwork for declaring objects of
custom types; however, this functionality is disabled
for now because of a potential loop in ASTImporter.

involved watching for the objective C built-in types in DWARF and making sure
when we convert the DWARF types into clang types that we use the appropriate
ASTContext types.
Added a way to find and dump types in lldb (something equivalent to gdb's
"ptype" command):
image lookup --type <TYPENAME>
This only works for looking up types by name and won't work with variables.
It also currently dumps out verbose internal information. I will modify it
to dump more appropriate user level info in my next submission.
Hookup up the "FindTypes()" functions in the SymbolFile and SymbolVendor so
we can lookup types by name in one or more images.
Fixed "image lookup --address <ADDRESS>" to be able to correctly show all
symbol context information, but it will only show this extra information when
the new "--verbose" flag is used.
Updated to latest LLVM to get a few needed fixes.

call Objective-C methods from expressions. Also added
some more logging to the function-calling thread plan
so that we can see the registers when a function
finishes.
Also documented things maybe a bit better.

Right now we mock up the function as a variadic
function when generating the IR for the call; we need
to eventually make the function be the right type if
the type is available.

it returns a list of functions as a SymbolContextList.
Rewrote the clients of SymbolContext to use this
SymbolContextList.
Rewrote some of the providers of the data to SymbolContext
to make them respect preferences as to whether the list
should be cleared first; propagated that change out.
ClangExpressionDeclMap and ClangASTSource use this new
function list to properly generate function definitions -
even for functions that don't have a prototype in the
debug information.

spurious guard variables on expression statics.
Updated the AST result synthesizer to eliminate the
unneeded result pointer.
Very rudimentary expressions now evaluate correctly
in the target using the new JIT-based mechanism.

- When we JIT an expression, we print the disassembly
of the generated code
- When we put the structure into the target, we print
the individual entries in the structure byte for
byte.

and moved it to its own header file for cleanliness.
Added more logging to ClangFunction so that we can
diagnose crashes in the executing expression.
Added code to extract the result of the expression
from the struct that is passed to the JIT-compiled
code.

defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO
and ObjectContainerUniversalMachO to be able to be cross compiled in Linux.
Also did some cleanup on the ASTType by renaming it to ClangASTType and
renaming the header file. Moved a lot of "AST * + opaque clang type *"
functionality from lldb_private::Type over into ClangASTType.

used by the JIT compiled expression, including the
result of the expression.
Also added a new class, ASTType, which encapsulates an
opaque Clang type and its associated AST context.
Refactored ClangExpressionDeclMap to use ASTTypes,
significantly reducing the possibility of mixups of
types from different AST contexts.

to do the JIT compilation and move the arguments
