- Limit invocations of CreateStackTrace() in ThreadHandler to
only unwind the topmost frame since that's all it actually
cares about anyways. Also adjust Step Over to use this
functionality in order to work with the correct frame addresses,
since the CPU frame pointer register isn't entirely what we want
here.
When stepping over, check to ensure that we're in the same call
frame that we started in. If not, reinstate the temporary breakpoint
and continue running.
When asked to step out, we now store the frame pointer of the current
stack frame. Upon hitting our temporary breakpoint, we then verify that
the current frame pointer is in fact in the previous frame. If not, we
reinstate the breakpoint and continue running.
- Add FindSection() and IsLoaded() calls to ElfFile.
- On init, cache the section start/end for the .text and .plt
sections in DwarfImageDebugInfo. Use them to make the check
for classifying addresses significantly cheaper.

Linkage Table section. Use that additional information to skip PLT entries
while stepping. Fixes#6974.

both accordingly.
* The threads view shows the thread states now. Also added tool tips with
additional info.

now be inspected. Still work in progress -- bit fields and arrays don't work
correctly yet nor does type lookup beyond the current compilation unit.
* Made most of the debugger output configurable via a config header. By default
it's much less noisy now.

* Fixed incorrect "step over" handling after hitting the temporary breakpoint.
Could cause stepping into functions.

- Made Job Referenceable.
- Turned JobKey into an abstract base class to add flexibility. The new
SimpleJobKey is a subclass with the former functionality.
* TeamWindow: Removed the TeamWindow* parameter from the listener hooks. The
TeamDebugger knows anyway.
* Added IDs to Variable, Function, and FunctionInstance. The latter two generate
the ID on the fly, Variable stores it.
* SpecificImageDebugInfo::CreateFrame(): Changed FunctionDebugInfo* debug
parameter to FunctionInstance* to provide more info (the function ID).
* DwarfInterfaceFactory/DwarfImageDebugInfo:
- Added class DwarfFunctionParameterID, an ID class implementation for
function parameters and set the IDs on the parameter objects.
- Retrieve the size of a type (i.e. the size of its objects) and store it in
DwarfType.
- If a parameter's ValueLocation doesn't have a size, set that of the
respective type.
- Map the register indicies in the parameters' ValueLocations from DWARF to
our indices.
* Added class TypeComponentPath for identifying subcomponents in types.
* Added class StackFrameValues, a container associating variables and their
subcomponents with values.
* StackFrame does now have a StackFrameValues object for parameters and local
variables and a mechanism to notify listeners when values have been retrieved.
* Added GetStackFrameValueJob to retrieve variable values. Lots of functionality
is missing yet. Most notably it doesn't retrieves values for subcomponents.
* Wired everything to trigger loading of variable values and getting notified
when done.
* VariablesView: Added a value column. This is all very basic and has to be
done differently, but at least values for the parameters can be seen already.

a good part of the source tree, so I rather get those changes into the
repository before continuing.
The general aim of the work is to deal with multiple instances of the same
function, e.g. inlined or non-inlined inline functions or those weird duplicates
gcc (4 at least) seems to be generating for no apparent reason.
* Added classes FunctionInstance (wrapping FunctionDebugInfo) and Function.
FunctionInstance represents a physical instance of a function (e.g. inlined
function at a particular address). A Function collects all FunctionInstances
referring to the same source code location.
* Moved the SourceCode property from FunctionDebugInfo to Function accordingly.
* Since SourceCode is no longer associated with a concrete function instance,
several methods dealing with statements have been removed and the
functionality has been provided through other means (e.g. TeamDebugModel or
SpecificImageDebugModel). This part is not yet completed.
* Introduced UserBreakpoint and UserBreakpointInstance. The user sets a
breakpoint at a source code location, which is represented by a
UserBreakpoint. Since that source location can be mapped to one address per
instance of the respective function, UserBreakpoint has a
UserBreakpointInstance per such function instance, which in turn refers to a
Breakpoint (an actual breakpoint at an address).
* Adjusted Breakpoint, BreakpointManager, and TeamDebugger accordingly.

* Added DebuggerInterface::GetSymbolInfo().
* Implementing stopping the thread in main() when the debugger started the
debugged program.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31393 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added TeamDebugInfo which serves as factory for ImageDebugInfos.
* Added the DWARF code to the build again. It's not used yet, though.

NULL after releasing its reference, so it could be released again later.
* No longer attach the source code to StackFrame, but rather to
FunctionDebugInfo. Besides being the more obvious place it also prevents
un-/reloading the source code when stepping. Only disadvantage is that we
never unload the source again yet.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31256 a95241bf-73f2-0310-859d-f6bbb57e9c96
support for temporary breakpoints.
* TeamDebugger: No longer handle debug events in the listener thread. Instead
post a message to the looper thread. Makes the locking a bit easier.
* Architecture: Added virtual GetInstructionInfo() and GetStatement() returning
information on the instruction respectively a statement at a given address.
Implemented for x86.
* DebugInfo: Added virtual GetStatement() and implemented it for
DebuggerDebugInfo by means of using the Architecture.
* Implemented step over/into/out support. Works in principle, but has no
handling for PLTs yet, i.e. stepping into functions of other libraries
requires two steps ATM.

* Added new job to get the initial state of a thread.
* Now we also get the states of new threads correctly.
