Sean Callanan b27a62fd13 Fixed a bug in the IR transformer where we were
trying to do replaceUsesOfWith on a constant,
which doesn't work.  Turns out we don't need to
do anything for constants.

Sean Callanan 8ade104a0a Changed SymbolContext so when you search for functions
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.

Sean Callanan 138e74e347 Fixed a bug where we didn't restore thread and
frame state after running a function.  This
caused nondeterministic crashes in the expression
evaluation code.

Sean Callanan ddb46efcca Updated the IR converter for the target to eliminate
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.

Sean Callanan 289e07b9d0 Added logging:
- 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.

Sean Callanan 6dde30e964 Added extensive logging of the code that is actually going
to be executed by the inferior.  This required explicit support
from RecordingMemoryManager for finding the address range
belonging to a particular function.

Also fixed a bug in DisassemblerLLVM where the disassembler
assumed there was an AddressRange available even when it was
NULL.

Sean Callanan ebf7707e53 Modified TaggedASTType to inherit from ClangASTType
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.

Greg Clayton e1a916a74d Change over to using the definitions for mach-o types and defines to the
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.

Sean Callanan 1d18066411 Added functionality to dematerialize values that were
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.

Greg Clayton 471b31ce62 Remove use of STL collection class use of the "data()" method since it isn't
part of C++'98. Most of these were "std::vector<T>::data()" and 
"std::string::data()".

2010-07-20 22:52:08 +00:00
Sean Callanan 6b4067c14e Added the necessary code to copy variables used by
an expression into the struct prepared for the JIT
compiled code to use.

Sean Callanan ea22d4288a Wrote the code that looks at a context to see
if the variables in that context allow a particular
JIT compiled expression to run in that context.

Sean Callanan 7618f4ebaf Fixes to the IR generator in the expression parser
to correctly unfold constant-folded global variables.
Also added code to JIT the expression.  Simple 
expressions are now JIT compiled successfully.

Greg Clayton b132097b45 I enabled some extra warnings for hidden local variables and for hidden
virtual functions and caught some things and did some general code cleanup.

Greg Clayton b6f75dfd96 Removed unused variable "log".
Fixed the llvm build for Mac OS X builds to look in llvm/lib/Release+Asserts 
output directory for all configurations (Debug, Release, BuildAndIntegration).

Sean Callanan 549c9f7f9a "expr -i" now performs the required transforms to
prepare the IR for JIT compilation.  We still need
to do the JIT compilation and move the arguments
in/out of target memory.

Greg Clayton c8e11e17aa Patch from Jean-Daniel Dupas:
Makefile patch to explicitly use PROJ_SRC_DIR when required. It fixes 
        build when obj dir is not source dir. 

I also fixed a build warning in ClangResultSynthesizer.cpp.

Greg Clayton c982c768d2 Merged Eli Friedman's linux build changes where he added Makefile files that
enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.

Jason Molenda ea84e76479 Switch over to using llvm's dwarf constants file.

Sean Callanan 2ab712f212 Added the skeleton of an IR transformer that will
prepare IR for execution in the target.  Wired the
expression command to use this IR transformer when
conversion to DWARF fails, and wired conversion to
DWARF to always fail (well, we don't generate any
DWARF...)

2010-07-03 01:35:46 +00:00
Sean Callanan 248e64b5b8 Fixes to improve logging (by printing basic
block labels) and produce cleaner IR (by removing
the thread-safe statics guards)

llvm-svn: 107528

Sean Callanan 177909a350 Small fixes to the DWARF relocator.

2010-07-02 21:28:35 +00:00
Sean Callanan 2df8a1f39c Added the skeleton of a transformation pass to
convert IR to DWARF.  So far, this pass only
performs a depth-first traversal of the IR,
logging each basic block as it finds it.

Greg Clayton d2d60ce388 Updated to llvm/clang from July 2, 2010 at 8:00AM.
llvm-svn: 107494
2010-07-02 18:39:06 +00:00
Sean Callanan 116be5347e Added a SemaConsumer that transforms the ASTs for
an expression, adding code to put the value of the
last expression (if there is one) into a variable
and write the address of that variable to a global
pointer.

llvm-svn: 107419
2010-07-01 20:08:22 +00:00
Sean Callanan 562a5a3904 Improved printing of LLVM IR. We now print
complete instructions rather than simply their
opcodes.

llvm-svn: 106708
2010-06-24 00:47:05 +00:00
Sean Callanan 1d389c4b02 Added the temporary -i option to expr, which
switches the expression parsing over to use the
LLVM IR as opposed to Clang ASTs.  Right now,
that functionality only logs.

llvm-svn: 106695
2010-06-23 23:18:04 +00:00
Sean Callanan d448c1ba04 Fixes for array handling and dynamic type casting
errors pointed out by John McCall.

llvm-svn: 106665
2010-06-23 18:58:10 +00:00
Sean Callanan f06ba8d89c Updated the expression parser to use proper logging when
looking for external variables.  Also cleaned up the log
messages coming from the DWARF interpreter.

llvm-svn: 106613
2010-06-23 00:47:48 +00:00
Sean Callanan 468574bd34 Added support to the expression parser for locating
externally-defined functions.

Greg Clayton 94e5d78888 Updated LLVM/Clang to revision from 2010-06-13T06:00.

Greg Clayton ef59f829e4 Switched over to using the new lldb::SharingPtr from Howard Hinnant.
We need to put this in LLDB since we need to vend this in our API
because our public API uses shared pointers to our private objects.

Removed a deprecated file: include/lldb/Host/Types.h

Added the new SharingPtr.cpp/.h files into source/Utility.

Added a shell script build phase that fixes up all headers in the
LLDB.framework.
