* Highlight the source view to indicate focus.
* Add rudimentary menu bar with quit and copy options (copy not yet working)

subclasses, though they don't do much yet. SourceCode is now associated with a
SourceLanguage.

DWARF expressions). Several related new classes: CfaRule[Set], CfaContext,
DwarfTargetInterface (for accessing target registers and memory).
* Implemented DwarfImageDebugInfo::CreateFrame(), so the DWARF frame info is
used for unwinding the stack.

- Added a type constant describing the format of the register value.
- Added flag "is callee-preserved" indicating whether the ABI requires the
register to be preserved by a called function.
* CpuState: Added SetRegisterValue(), made GetRegisterValue() const.
* Added RegisterMap interface for mapping register indices between different
models.
* Architecture:
- Added CreateCpuState() version to create a clean CpuState.
- Added GetDwarfRegisterMaps(), which returns to RegisterMaps, converting
from and to DWARF register indices.
- Added ReadValueFromMemory() reading a value from the target team's memory.
The value type is specified by a type constant and the value return via a
BVariant.
- CreateStackTrace: No longer decide whether to adjust the instruction pointer
of the previous CPU state depending on who created the CPU state. Instead
compare it with the return address of the next frame. If they are equal it
obviously has to be adjusted.

FunctionInstance does now also have a (DisassembledCode) source code
attribute. Function keeps its attribute, but it explicitly is a
FileSourceCode now.
* SourceCode:
- Removed GetStatementAtLocation(). Instead DisassembledCode has a
StatementAtLocation() now. As well as a StatementAtAddress() and
StatementAddressRange(). Rather cast to the subclass (in two instances)
instead of having those methods in the base class. In most cases we already
have the subclasses now, anyway.
- Added Lock()/Unlock(), which are implemented in FileSourceCode. The
statement ranges are no longer immutable, so we have to lock.
* TeamDebugModel:
- Revived GetBreakpointsInAddressRange().
- GetBreakpointsForSourceCode(): Optimized for DisassembledCode and fixed
in the FileSourceCode case. We need to compare with the functions' source
file instead of their source code, since they might not have the source
code set yet. Fixed two instances of the same problem in SourceView. Setting
breakpoints in functions that have no associated source code yet, works now.
* Team:
- GetStatementAtAddress(): Optimized by using the DisassembledCode, if
available.
- GetStatementAtSourceLocation(): If the supplied source code is
DisassembledCode, we have to get the statement from it directly, since
we can't get that information from the image debug info.
* TeamDebugInfo: Added LoadSourceCode() and DisassembleFunction(), the new way
to get FileSourceCode respectively DisassembledCode. SpecificTeamDebugInfo
has lost LoadSourceCode() and gained service methods AddSourceCodeInfo() and
ReadCode(). This avoids unnecessary code duplication in the subclasses.
Moreover it allows for joining source location info source files from
different images (and compilation units) -- interesting for inline functions
in headers.
* Adjusted LoadSourceCodeJob and TeamDebugger::FunctionSourceCodeRequested()
accordingly.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31514 a95241bf-73f2-0310-859d-f6bbb57e9c96
- Replaced StatementAtLine() by GetStatementLocationRange(), which doesn't
return a statement (i.e. also target addresses), but just a range in the
source code. This can also be implemented by FileSourceCode, which can
therefore be used for more than one instance of a function.
- Added GetStatementAtLocation() which kind of is also a replacement for
StatementAtLine(), but is optional and only provided by
DisassembledSourceCode.
- Added GetSourceFile(), which has to be provided when
GetStatementAtLocation() is not implemented.
- Kicked the statement stuff out of FileSourceCode. It only knows source
ranges, now.
* Team: Added GetStatementAtSourceLocation(), which is the real replacement for
SourceCode::StatementAtLine() in cases where a statement is actually
needed. It uses SourceCode::GetStatementAtLocation(), if available and
otherwise finds a function at the source location, and gets a statement for
one of its instances.
* TeamDebugInfo: Does now manage a source file -> functions map allowing to
look up functions at source file locations.
* DwarfImageDebugInfo:
- Switched the path in the source code hash table key for a LocatableFile,
which is cheaper to hash and to compare.
- Fixed bugs where the relocation delta was ignored.
- Replace a -1 in the SourceLocation column component by 0 to avoid
mismatches.
* SourceLocation: Changed component types from uint32 to int32. Otherwise -1 is
not representable.
Things mostly work as before starting the refactoring to support function
instances. All is not well yet, though. E.g. we don't merge the source code
information for common source files (like headers) provided by different
compilation units (or even images) yet. We need to do that, since the debug
info for a compilation unit only contains line number information for inline
functions (in headers) that are actually used.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31495 a95241bf-73f2-0310-859d-f6bbb57e9c96
attributes returning for each whether it was set on the entry.
* DwarfUtils::GetDeclarationLocation(): Entries can just override individual
declaration location attributes. E.g. for a specification entry file, line,
and column can be given, while the entry for the implementation could just
override the line, if it is implemented in the same file (like inline methods
in a header).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31493 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31447 a95241bf-73f2-0310-859d-f6bbb57e9c96
the function is actually inlined, which we already checked for anyway. Now the
source location info should be retrieved correctly for all functions, even if
if we get potential duplicates for non-inlined functions. This has to be
dealt with differently, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31400 a95241bf-73f2-0310-859d-f6bbb57e9c96
* GetDeclarationLocation():
- Don't fail already when the entry itself doesn't support a declaration
location, since that fails for inlined functions.
- Follow abstract origin and specification, even if they don't have a have
a declaration location. The latter doesn't matter in this case, but we
failed erroneously, if the abstract origin had a specification which in
turn had the declaration location info.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31399 a95241bf-73f2-0310-859d-f6bbb57e9c96
only file names. Changed the FileManager::Get*File() method versions taking
directory path and file name to also accept relative file paths. They just join
the paths and use the single-argument versions, which now does all the work.
Fixes finding source files for which a relative path is given in .debug_line.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31394 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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
- Got rid of superfluous SetTeam().
- Aded SetThread() to select a thread.
* TeamWindow: When a thread hits a debug event and no thread is selected or
the selected thread is running, select the stopped thread and switch to the
"Threads" tab view.

attributes, but apparently those aren't generated by gcc 2.

to int32&. The DWARF indices are one-based with 0 as invalid/no value, but we
subtract one to get real indices and -1 as special value.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31384 a95241bf-73f2-0310-859d-f6bbb57e9c96
- DwarfUtils::GetDeclarationLocation(): Line/column numbers are one-based.
- Added line number program interpretation (LineNumberProgram).
* FunctionDebugInfo: Return the source file (LocatableFile) instead of the
file name.
* FileManager/LocatableEntry: Fixed handling when a LocatableEntry is
unreferenced. There was a race condition before, since an unreferenced entry
could be referenced and unreferenced again before removing it from the hash
table, which could lead to double deletion. Now we never reuse an unreferenced
entry and just remove it from the hash table when encountering one.
* FileManager/SourceFile: Added class SourceFile which loads a source file from
disk and slices it into lines. Managed by FileManager.
* Added class FileSourceCode, a SourceCode implementation using a SourceFile as
line provider. The statement management works pretty much exactly as in
DissassembledCode.
* DwarfImageDebugInfo: Implemented LoadSourceCode for real. It creates a
FileSourceCode and uses the DWARF line number information for the statement
information. This basically gets the source level view going, though there
are still several problems -- stepping doesn't work perfectly yet, the source
isn't found for all functions, there's no handling of duplicate functions (no
idea why gcc generates them in the first place), etc.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31382 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added StringUtils with string hash functions.
* Added Locatable{Entry,File,Directory} and FileManager classes to manage the
mapping from debug info/target file names to local file names.
* Image does now have a LocatableFile referring to the image's shared object
file. Added listening to location changes of these files to TeamDebugger. No
action is taken yet (should trigger reloading the debug info).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31368 a95241bf-73f2-0310-859d-f6bbb57e9c96
compilation unit. It can be referenced by the file entries in the line info
header, too (index 0).

to the DwarfFunctionDebugInfo objects. The functions do now appear organized
by source file in the function list view. Unfortunately the list view is too
small to look as clear as it should. Got to think of something else I'm afraid.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31326 a95241bf-73f2-0310-859d-f6bbb57e9c96
the include directory and source file names to CompilationUnit.
* Added DwarfUtils::GetDeclarationLocation() which retrieves the respective
source file name and line/column index for a given DIE.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31325 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Fixed typo in SetImageDebugInfo() setting the wrong source file function
start indices.
* Fixed incorrect return values in _CompareSourceFileNames().
* Fixed several instances of ignoring the source file's function start index.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31323 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Created "types" subdirectory for basic types and moved Types.h,
SourceLocation, TargetAddressRange there.
* Added TargetAddressRangeList, representing a list of address ranges.
* Array: Added copy constructor and assignment operator.
* Added DwarfFunctionDebugInfo.
* ElfFile: Also read the program headers and provide access to the segment
information.
* DWARF:
- Some work on DIECompileUnitBase and DIESubprogram to handle attributes we
need.
- Added DwarfUtils class which provides static utility methods. Currently some
to get DIE names. Only provisionally implemented yet.
- Read range list attribute values from the .debug_ranges section. Extended
AttributeValue to handle them correctly (ref-counting).
* DwarfImageDebugInfo:
- Implemented GetFunctions() for real, i.e. we return functions for all
subprogram debug info entries we find (those that refer to actual
functions, that is).
- Implemented the fallback part of LoadSourceCode() (reading the code from the
file and disassembling it).
Things should hopefully work as before, just a bit slower and with less accurate
function names, if DWARF debug info is available. Promising, eh? ;-)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31321 a95241bf-73f2-0310-859d-f6bbb57e9c96
nicer access.
* A CompilationUnit does now know its debug info entry.
