Sean Callanan 4cf04d209b Set a CodeGenOption in Clang to inhibit insertion
of profiling code into expressions.

Modified IRForTarget to emit array and record
member accesses correctly.  (Reading and writing
both work.)

Sean Callanan 5300d37aa7 Added support for rewriting objc_msgSend so we can
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.

Johnny Chen 7dc2e4784e We can do better when reporting the status of one-liner script execution.
Change the prototype of ScriptInterpreter::ExecuteOneLine() to return bool
instead of void and take one additional parameter as CommandReturnObject *.

Propagate the status of one-liner execution back appropriately.

2010-07-29 20:38:50 +00:00
Greg Clayton 5fb47cd535 Fixed "void *ClangASTContext::CreatePointerType (void *clang_type);" to return objective C pointers for clang::Type::TypeClass types that are "clang::Type::ObjCObject" and "clang::Type::ObjCInterface" .
llvm-svn: 109795

Johnny Chen 1bb9bc72b9 Fixed "warning: unused variable 'log'".
llvm-svn: 109794
2010-07-29 19:51:52 +00:00
Greg Clayton 4b4b5fcebc Fixed expression result printing to have the expression result type be in
parens and to have a space before the value.

Before:
(lldb) expr 3 + 1
int4

(lldb) expr 3 + 1
(int) 4

Greg Clayton 9e40956aea Created lldb::LanguageType by moving an enumeration from the
lldb_private::Language class into the enumerations header so it can be freely
used by other interfaces.

Added correct objective C class support to the DWARF symbol parser. Prior to
this fix we were parsing objective C classes as C++ classes and now that the
expression parser is ready to call functions we need to make sure the objective
C classes have correct AST types.

llvm-svn: 109574
2010-07-28 02:04:09 +00:00
Sean Callanan cc54bd3cef Added and improved logging. This is helping us as we
diagnose a problem where we're not correctly emitting
PIC code.

llvm-svn: 109568
2010-07-28 01:00:59 +00:00
Sean Callanan 7ea3501bd8 Added support for calling functions from expressions.
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.

llvm-svn: 109543
2010-07-27 21:39:39 +00:00
Sean Callanan 4edba2d130 Added support for locating a function that is
referenced in the IR.  We don't yet support updating
the call to that function.

llvm-svn: 109483
2010-07-27 02:07:53 +00:00
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.

llvm-svn: 109477
2010-07-27 01:17:28 +00:00
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.

2010-07-27 00:55:47 +00:00
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.

Stephen Wilson e6f9f66b39 Add a new Process plugin for Linux.
This component is still at an early stage, but allows for simple
breakpoint/step-over operations and basic process control.

The makefiles are set up to build the plugin under Linux only.

2010-07-24 02:19:04 +00:00
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.

2010-07-24 01:37:44 +00:00
Greg Clayton 9fed0d85b2 Added needed breakpoint functionality to the public API that includes:
SBTarget:
    - get breakpoint count
    - get breakpoint at index
  SBBreakpoint:
    - Extract data from breakpoint events

llvm-svn: 109281
2010-07-23 22:50:09 +00:00
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.

Greg Clayton 896dff661a Centralized the Mach exception stop info code by adding it as a first
class citizen on the StopInfo class. 

llvm-svn: 109235

Greg Clayton 572404311a Remove a deadlock condition. A bit of explanation is needed: When calling
ThreadCancel in Host::WillTerminate g_monitor_thread may be blocked on a call
to pthread_cond_wait (for example, line 640).  Now, by default, when a 
cancellation request is serviced g_monitor_thread will again own the mutex
guarding the condition variable it was waiting on.  This causes the call to 
SetValue in Host::WillTerminate to hit a deadlock.

The call to SetValue does not appear to be needed, so removing it solves
the issue.

Patch from Stephen Wilson.

2010-07-23 15:47:19 +00:00
Greg Clayton 26661bca20 Remove a premature invalidation of a threads pthread_t handle, thus avoiding
a segfault when calling pthread_cancel.  Also, sets m_read_thread_enabled if
the thread is actually spawned.

Patch from Stephen Wilson.

Greg Clayton 5b9a1ea9c6 Added Mach exception stop descriptions. The chunk of code I just added needs to be placed into a utility location so it can be used by ProcessMacOSX and debugserver.
llvm-svn: 109214
2010-07-23 03:40:38 +00:00
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.

llvm-svn: 109209
2010-07-23 02:19:15 +00:00
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.

2010-07-23 00:16:21 +00:00
Greg Clayton 49182ed65a This patch changes the point at which Process::m_private_state_thread is
invalidated.  There was a race condition where the private thread would
invalidate its own pthread_t object before the parent could perform a
pthread_cancel/pthread_join sequence.

Patch from Stephen Wilson.

llvm-svn: 109131
2010-07-22 18:34:21 +00:00
Greg Clayton 8cf0593c87 Added a new enumeration named "ClangASTContext::AccessType" that abstracts the type creation from the various access enumerations in Clang. Currently there are clang::AccessSpecifier and the objective C ivars have their own enumeration. So I added a new enumeration that will allow a consistent interface when creating types through ClangASTContext.
I also added new functions to create an Objective C class, ivar and set an objective C superclass. They aren't hooked up in the DWARF parser yet. That is the next step, though I am unsure if I will do this in the DWARF parser or try and do it generically in the existing Record manipulation functions.

2010-07-22 18:30:50 +00:00
Greg Clayton 4ceb9980c8 Modified both the ObjectFileMachO and ObjectFileELF to correctly set the
SectionType for Section objects for DWARF.

Modified the DWARF plug-in to get the DWARF sections by SectionType so we
can safely abstract the LLDB core from section names for the various object
file formats.

Modified the SectionType definitions for .debug_pubnames and .debug_pubtypes
to use the correct case.

llvm-svn: 109054
2010-07-21 22:54:26 +00:00
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.

llvm-svn: 109046

Greg Clayton a0e7f0c1b1 Avoid std::bitset<64>::to_string() since it is missing in earlier C++
libraries (from William Lynch).

llvm-svn: 108976
2010-07-21 01:08:41 +00:00
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()".

Stephen Wilson 50bd94f961 Have Process::CreateBreakpointSite return a break_id_t instead of a user_id_t.
Also, update BreakpointLocation::ResolveBreakpointSite to check for invalid
breakpoint ID's using the proper magic constant.
