more of the local path, platform path, associated symbol file, UUID, arch,
object name and object offset. This allows many of the calls that were
GetSharedModule to reduce the number of arguments that were used in a call
to these functions. It also allows a module to be created with a ModuleSpec
which allows many things to be specified prior to any accessors being called
on the Module class itself. 

I was running into problems when adding support for "target symbol add"
where you can specify a stand alone debug info file after debugging has started
where I needed to specify the associated symbol file path and if I waited until
after construction, the wrong  symbol file had already been located. By using
the ModuleSpec it allows us to construct a module with as little or as much
information as needed and not have to change the parameter list.

interface (.i) files for each class.

Changed the FindFunction class from:

uint32_t
SBTarget::FindFunctions (const char *name, 
                         uint32_t name_type_mask, 
                         bool append, 
                         lldb::SBSymbolContextList& sc_list)

uint32_t
SBModule::FindFunctions (const char *name, 
                         uint32_t name_type_mask, 
                         bool append, 
                         lldb::SBSymbolContextList& sc_list)

To:

lldb::SBSymbolContextList
SBTarget::FindFunctions (const char *name, 
                         uint32_t name_type_mask = lldb::eFunctionNameTypeAny);

lldb::SBSymbolContextList
SBModule::FindFunctions (const char *name,
                         uint32_t name_type_mask = lldb::eFunctionNameTypeAny);

This makes the API easier to use from python. Also added the ability to
append a SBSymbolContext or a SBSymbolContextList to a SBSymbolContextList.

Exposed properties for lldb.SBSymbolContextList in python:

lldb.SBSymbolContextList.modules => list() or all lldb.SBModule objects in the list
lldb.SBSymbolContextList.compile_units => list() or all lldb.SBCompileUnits objects in the list
lldb.SBSymbolContextList.functions => list() or all lldb.SBFunction objects in the list
lldb.SBSymbolContextList.blocks => list() or all lldb.SBBlock objects in the list
lldb.SBSymbolContextList.line_entries => list() or all lldb.SBLineEntry objects in the list
lldb.SBSymbolContextList.symbols => list() or all lldb.SBSymbol objects in the list

This allows a call to the SBTarget::FindFunctions(...) and SBModule::FindFunctions(...)
and then the result can be used to extract the desired information:

sc_list = lldb.target.FindFunctions("erase")

for function in sc_list.functions:
    print function
for symbol in sc_list.symbols:
    print symbol

Exposed properties for the lldb.SBSymbolContext objects in python:

lldb.SBSymbolContext.module => lldb.SBModule
lldb.SBSymbolContext.compile_unit => lldb.SBCompileUnit
lldb.SBSymbolContext.function => lldb.SBFunction
lldb.SBSymbolContext.block => lldb.SBBlock
lldb.SBSymbolContext.line_entry => lldb.SBLineEntry
lldb.SBSymbolContext.symbol => lldb.SBSymbol


Exposed properties for the lldb.SBBlock objects in python:

lldb.SBBlock.parent => lldb.SBBlock for the parent block that contains
lldb.SBBlock.sibling => lldb.SBBlock for the sibling block to the current block
lldb.SBBlock.first_child => lldb.SBBlock for the first child block to the current block
lldb.SBBlock.call_site => for inline functions, return a lldb.declaration object that gives the call site file, line and column
lldb.SBBlock.name => for inline functions this is the name of the inline function that this block represents
lldb.SBBlock.inlined_block => returns the inlined function block that contains this block (might return itself if the current block is an inlined block)
lldb.SBBlock.range[int] => access the address ranges for a block by index, a list() with start and end address is returned
lldb.SBBlock.ranges => an array or all address ranges for this block
lldb.SBBlock.num_ranges => the number of address ranges for this blcok

SBFunction objects can now get the SBType and the SBBlock that represents the
top scope of the function.

SBBlock objects can now get the variable list from the current block. The value
list returned allows varaibles to be viewed prior with no process if code
wants to check the variables in a function. There are two ways to get a variable
list from a SBBlock:

lldb::SBValueList
SBBlock::GetVariables (lldb::SBFrame& frame,
                       bool arguments,
                       bool locals,
                       bool statics,
                       lldb::DynamicValueType use_dynamic);

lldb::SBValueList
SBBlock::GetVariables (lldb::SBTarget& target,
                       bool arguments,
                       bool locals,
                       bool statics);

When a SBFrame is used, the values returned will be locked down to the frame
and the values will be evaluated in the context of that frame.

When a SBTarget is used, global an static variables can be viewed without a
running process.

so that we don't have "fprintf (stderr, ...)" calls sprinkled everywhere.
Changed all needed locations over to using this.

For non-darwin, we log to stderr only. On darwin, we log to stderr _and_
to ASL (Apple System Log facility). This will allow GUI apps to have a place
for these error and warning messages to go, and also allows the command line
apps to log directly to the terminal.

llvm-svn: 147596

process IDs, and thread IDs, but was mainly needed for for the UserID's for
Types so that DWARF with debug map can work flawlessly. With DWARF in .o files
the type ID was the DIE offset in the DWARF for the .o file which is not
unique across all .o files, so now the SymbolFileDWARFDebugMap class will
make the .o file index part (the high 32 bits) of the unique type identifier
so it can uniquely identify the types.

llvm-svn: 142534

Specifically, the expression parser used to use
functions attached to SymbolContext to do lookups,
but nowadays it searches a ModuleList or Module
directly instead.  These functions had no
remaining clients so I removed them to prevent
bit rot.

I also removed a stray callback function from
ClangExpressionDeclMap.

llvm-svn: 141899

down through Module and SymbolVendor into SymbolFile.
Added checks to SymbolFileDWARF that restrict symbol
searches when a namespace is passed in.

llvm-svn: 141348

Fixed an assertion that was causing a crash. The bug describes a case where we have an inlined block that doesn't contain the frame PC that was used to lookup the symbol context in the first place. This really shouldn't happen, so
now we log if we run into this and don't assert.

llvm-svn: 141338

index the DWARF. Also fixed an issue with memory accelerator tables with a
size of 1 where we would loop infinitely.

Added support for parsing the new .apple_namespaces section which gives us a
memory hash table for looking up namespaces.

llvm-svn: 141128

symbol context that represents an inlined function. This function has been
renamed internally to:

bool
SymbolContext::GetParentOfInlinedScope (const Address &curr_frame_pc, 
                                        SymbolContext &next_frame_sc, 
                                        Address &next_frame_pc) const;
                                        
And externally to:

SBSymbolContext
SBSymbolContext::GetParentOfInlinedScope (const SBAddress &curr_frame_pc, 
                                          SBAddress &parent_frame_addr) const;

The correct blocks are now correctly calculated.

Switched the stack backtracing engine (in StackFrameList) and the address
context printing over to using the internal SymbolContext::GetParentOfInlinedScope(...) 
so all inlined callstacks will match exactly.

llvm-svn: 140910

are available, we currently will still index the DWARF ourselves
and assert if the name lookups differ. This will help us transition
to the new accelerator tables and make sure they are workng before
we switch over entirely.

function name from a symbol context.  Use that in CommandCompletions
to get the right name.

symbolication. Also improved the SBInstruction API to allow
access to the instruction opcode name, mnemonics, comment and
instruction data.

Added the ability to edit SBLineEntry objects (change the file,
line and column), and also allow SBSymbolContext objects to be
modified (set module, comp unit, function, block, line entry
or symbol). 

The SymbolContext and SBSymbolContext can now generate inlined
call stack infomration for symbolication much easier using the
SymbolContext::GetParentInlinedFrameInfo(...) and 
SBSymbolContext::GetParentInlinedFrameInfo(...) methods.

llvm-svn: 140518

stdarg formats to use __attribute__ format so the compiler can flag
incorrect uses.  Fix all incorrect uses.  Most of these are innocuous,
a few were resulting in crashes.

llvm-svn: 140185

We had some cases where getting the shared pointer for a module from
the global module list was causing a performance issue when debugging
with DWARF in .o files. Now that the module uses intrusive ref counts,
we can easily convert any pointer to a shared pointer.

llvm-svn: 139983

by name by adding an extra parameter to the lldb_private::Target breakpoint 
setting functions.

Added a function in the DWARF symbol file plug-in that can dump errors
and prints out which DWARF file the error is happening in so we can track
down what used to be assertions easily.

Fixed the MacOSX kernel plug-in to properly read the kext images and set
the kext breakpoint to watch for kexts as they are loaded.

llvm-svn: 134990

 - a new --name option for "type summary add" lets you give a name to a summary
 - a new --summary option for "frame variable" lets you bind a named summary to one or more variables
${var%s} now works for printing the value of 0-terminated CStrings
type format test case now tests for cascading
 - this is disabled on GCC because GCC may end up stripping typedef chains, basically breaking cascading
new design for the FormatNavigator class
new template class CleanUp2 meant to support cleanup routines with 1 additional parameter beyond resource handle

use lldb_private::Target::ReadMemory(...) to allow constant strings
to be displayed in global variables prior on in between process
execution.

Centralized the variable declaration dumping into:

	bool
	Variable::DumpDeclaration (Stream *s, bool show_fullpaths, bool show_module);

Fixed an issue if you used "target variable --regex <regex>" where the
variable name would not be displayed, but the regular expression would.

Fixed an issue when viewing global variables through "target variable"
might not display correctly when doing DWARF in object files.

llvm-svn: 134878

looked up.  Queries for global types were made
too specific -- including the current module
and compile unit in the query was limiting the
search when we wanted a truly global search.

llvm-svn: 131145

inline contexts when the deepest most block is not inlined.

Added source path remappings to the lldb_private::Target class that allow it
to remap paths found in debug info so we can find source files that are elsewhere
on the current system.

Fixed disassembly by function name to disassemble inline functions that are
inside other functions much better and to show enough context before the
disassembly output so you can tell where things came from.

Added the ability to get more than one address range from a SymbolContext 
class for the case where a block or function has discontiguous address ranges.

llvm-svn: 130044

line tables specify breakpoints can be set in the source. When dumping the
source, the number of breakpoints that can be set on a source line are shown
as a prefix:

(lldb) source list -f test.c -l1 -c222 -b
       1   	#include <stdio.h>
       2   	#include <sys/fcntl.h>
       3   	#include <unistd.h>
       4   	int
       5   	sleep_loop (const int num_secs)
[2]    6   	{
       7   	    int i;
[1]    8   	    for (i=0; i<num_secs; ++i)
       9   	    {
[1]    10  	        printf("%d of %i - sleep(1);\n", i, num_secs);
[1]    11  	        sleep(1);       
       12  	    }
       13  	    return 0;
[1]    14  	}
       15  	
       16  	int 
       17  	main (int argc, char const* argv[])
[1]    18  	{
[1]    19  	    printf("Process: %i\n\n", getpid());
[1]    20  	    puts("Press any key to continue..."); getchar();
[1]    21  	    sleep_loop (20);
       22  	    return 12;
[1]    23  	}

Above we can see there are two breakpoints for line 6 and one breakpoint for
lines 8, 10, 11, 14, 18, 19, 20, 21 and 23. All other lines have no line table
entries for them. This helps visualize the data provided in the debug 
information without having to manually dump all line tables. It also includes
all inline breakpoint that may result for a given file which can also be very
handy to see.

This allows you to have a platform selected, then specify a triple using
"i386" and have the remaining triple items (vendor, os, and environment) set
automatically.

Many interpreter commands take the "--arch" option to specify an architecture
triple, so now the command options needed to be able to get to the current
platform, so the Options class now take a reference to the interpreter on
construction.

Modified the build LLVM building in the Xcode project to use the new
Xcode project level user definitions:

LLVM_BUILD_DIR - a path to the llvm build directory
LLVM_SOURCE_DIR - a path to the llvm sources for the llvm that will be used to build lldb
LLVM_CONFIGURATION - the configuration that lldb is built for (Release, 
Release+Asserts, Debug, Debug+Asserts).

I also changed the LLVM build to not check if "lldb/llvm" is a symlink and
then assume it is a real llvm build directory versus the unzipped llvm.zip
package, so now you can actually have a "lldb/llvm" directory in your lldb
sources.

llvm-svn: 129112

class now implements the Host functionality for a lot of things that make 
sense by default so that subclasses can check:

int
PlatformSubclass::Foo ()
{
    if (IsHost())
        return Platform::Foo (); // Let the platform base class do the host specific stuff
    
    // Platform subclass specific code...
    int result = ...
    return result;
}

Added new functions to the platform:

    virtual const char *Platform::GetUserName (uint32_t uid);
    virtual const char *Platform::GetGroupName (uint32_t gid);

The user and group names are cached locally so that remote platforms can avoid
sending packets multiple times to resolve this information.

Added the parent process ID to the ProcessInfo class. 

Added a new ProcessInfoMatch class which helps us to match processes up
and changed the Host layer over to using this new class. The new class allows
us to search for processs:
1 - by name (equal to, starts with, ends with, contains, and regex)
2 - by pid
3 - And further check for parent pid == value, uid == value, gid == value, 
    euid == value, egid == value, arch == value, parent == value.
    
This is all hookup up to the "platform process list" command which required
adding dumping routines to dump process information. If the Host class 
implements the process lookup routines, you can now lists processes on 
your local machine:

machine1.foo.com % lldb
(lldb) platform process list 
PID    PARENT USER       GROUP      EFF USER   EFF GROUP  TRIPLE                   NAME

This of course also works remotely with the lldb-platform:

The lldb-platform implements everything with the Host:: layer, so this should
"just work" for linux. I will probably be adding more stuff to the Host layer
for launching processes and attaching to processes so that this support should
eventually just work as well.

Modified the target to be able to be created with an architecture that differs
from the main executable. This is needed for iOS debugging since we can have
an "armv6" binary which can run on an "armv7" machine, so we want to be able
to do:

% lldb
(lldb) platform create remote-ios
(lldb) file --arch armv7 a.out

Where "a.out" is an armv6 executable. The platform then can correctly decide
to open all "armv7" images for all dependent shared libraries.

Modified the disassembly to show the current PC value. Example output:

(lldb) disassemble --frame
a.out`main:
   0x1eb7:  pushl  %ebp
   0x1eb8:  movl   %esp, %ebp
   0x1eba:  pushl  %ebx
   0x1ebb:  subl   $20, %esp
   0x1ebe:  calll  0x1ec3                   ; main + 12 at test.c:18
   0x1ec3:  popl   %ebx
-> 0x1ec4:  calll  0x1f12                   ; getpid
   0x1ec9:  movl   %eax, 4(%esp)
   0x1ecd:  leal   199(%ebx), %eax
   0x1ed3:  movl   %eax, (%esp)
   0x1ed6:  calll  0x1f18                   ; printf
   0x1edb:  leal   213(%ebx), %eax
   0x1ee1:  movl   %eax, (%esp)
   0x1ee4:  calll  0x1f1e                   ; puts
   0x1ee9:  calll  0x1f0c                   ; getchar
   0x1eee:  movl   $20, (%esp)
   0x1ef5:  calll  0x1e6a                   ; sleep_loop at test.c:6
   0x1efa:  movl   $12, %eax
   0x1eff:  addl   $20, %esp
   0x1f02:  popl   %ebx
   0x1f03:  leave
   0x1f04:  ret
   
This can be handy when dealing with the new --line options that was recently
added:

(lldb) disassemble --line
a.out`main + 13 at test.c:19
   18  	{
-> 19  		printf("Process: %i\n\n", getpid());
   20  	    puts("Press any key to continue..."); getchar();
-> 0x1ec4:  calll  0x1f12                   ; getpid
   0x1ec9:  movl   %eax, 4(%esp)
   0x1ecd:  leal   199(%ebx), %eax
   0x1ed3:  movl   %eax, (%esp)
   0x1ed6:  calll  0x1f18                   ; printf

Modified the ModuleList to have a lookup based solely on a UUID. Since the
UUID is typically the MD5 checksum of a binary image, there is no need
to give the path and architecture when searching for a pre-existing
image in an image list.

Now that we support remote debugging a bit better, our lldb_private::Module
needs to be able to track what the original path for file was as the platform
knows it, as well as where the file is locally. The module has the two 
following functions to retrieve both paths:

const FileSpec &Module::GetFileSpec () const;
const FileSpec &Module::GetPlatformFileSpec () const;

llvm-svn: 128563

an architecture into ArchSpec:

uint32_t
ArchSpec::GetMinimumOpcodeByteSize() const;

uint32_t
ArchSpec::GetMaximumOpcodeByteSize() const;

Added an AddressClass to the Instruction class in Disassembler.h.
This allows decoded instructions to know know if they are code,
code with alternate ISA (thumb), or even data which can be mixed
into code. The instruction does have an address, but it is a good
idea to cache this value so we don't have to look it up more than 
once.

Fixed an issue in Opcode::SetOpcodeBytes() where the length wasn't
getting set.

Changed:

	bool
	SymbolContextList::AppendIfUnique (const SymbolContext& sc);

To:
	bool
	SymbolContextList::AppendIfUnique (const SymbolContext& sc, 
									   bool merge_symbol_into_function);

This function was typically being used when looking up functions
and symbols. Now if you lookup a function, then find the symbol,
they can be merged into the same symbol context and not cause
multiple symbol contexts to appear in a symbol context list that
describes the same function.

Fixed the SymbolContext not equal operator which was causing mixed
mode disassembly to not work ("disassembler --mixed --name main").

Modified the disassembler classes to know about the fact we know,
for a given architecture, what the min and max opcode byte sizes
are. The InstructionList class was modified to return the max
opcode byte size for all of the instructions in its list.
These two fixes means when disassemble a list of instructions and dump 
them and show the opcode bytes, we can format the output more 
intelligently when showing opcode bytes. This affects any architectures
that have varying opcode byte sizes (x86_64 and i386). Knowing the max
opcode byte size also helps us to be able to disassemble N instructions
without having to re-read data if we didn't read enough bytes.

Added the ability to set the architecture for the disassemble command.
This means you can easily cross disassemble data for any supported 
architecture. I also added the ability to specify "thumb" as an 
architecture so that we can force disassembly into thumb mode when
needed. In GDB this was done using a hack of specifying an odd
address when disassembling. I don't want to repeat this hack in LLDB,
so the auto detection between ARM and thumb is failing, just specify
thumb when disassembling:

(lldb) disassemble --arch thumb --name main

You can also have data in say an x86_64 file executable and disassemble
data as any other supported architecture:
% lldb a.out
Current executable set to 'a.out' (x86_64).
(lldb) b main
(lldb) run
(lldb) disassemble --arch thumb --count 2 --start-address 0x0000000100001080 --bytes
0x100001080:  0xb580 push   {r7, lr}
0x100001082:  0xaf00 add    r7, sp, #0

Fixed Target::ReadMemory(...) to be able to deal with Address argument object
that isn't section offset. When an address object was supplied that was
out on the heap or stack, target read memory would fail. Disassembly uses
Target::ReadMemory(...), and the example above where we disassembler thumb
opcodes in an x86 binary was failing do to this bug.

llvm-svn: 128347

Add a first pass at a "stop hook" mechanism.  This allows you to add commands that get run every time the debugger stops, whether due to a breakpoint, the end of a step, interrupt, etc.  You can also specify in which context you want the stop hook to run, for instance only on a particular thread, or only in a particular shared library, function, file, line range within a file.

Still need to add "in methods of a class" to the specifiers, and the ability to write the stop hooks in the Scripting language as well as in the Command Language.

of Stephen Wilson's idea (thanks for the input Stephen!). What I ended up
doing was:
- Got rid of ArchSpec::CPU (which was a generic CPU enumeration that mimics
  the contents of llvm::Triple::ArchType). We now rely upon the llvm::Triple 
  to give us the machine type from llvm::Triple::ArchType.
- There is a new ArchSpec::Core definition which further qualifies the CPU
  core we are dealing with into a single enumeration. If you need support for
  a new Core and want to debug it in LLDB, it must be added to this list. In
  the future we can allow for dynamic core registration, but for now it is
  hard coded.
- The ArchSpec can now be initialized with a llvm::Triple or with a C string
  that represents the triple (it can just be an arch still like "i386").
- The ArchSpec can still initialize itself with a architecture type -- mach-o
  with cpu type and subtype, or ELF with e_machine + e_flags -- and this will
  then get translated into the internal llvm::Triple::ArchSpec + ArchSpec::Core.
  The mach-o cpu type and subtype can be accessed using the getter functions:
  
  uint32_t
  ArchSpec::GetMachOCPUType () const;

  uint32_t
  ArchSpec::GetMachOCPUSubType () const;
  
  But these functions are just converting out internal llvm::Triple::ArchSpec 
  + ArchSpec::Core back into mach-o. Same goes for ELF.

All code has been updated to deal with the changes.

This should abstract us until later when the llvm::TargetSpec stuff gets
finalized and we can then adopt it.

a Stream, and then added GetOutputData & GetErrorData to get the accumulated data.
- Added a StreamTee that will tee output to two provided lldb::StreamSP's.
- Made the CommandObjectReturn use this so you can Tee the results immediately to
the debuggers output file, as well as saving up the results to return when the command
is done executing.
- HandleCommands now uses this so that if you have a set of commands that continue the target
you will see the commands come out as they are processed.
- The Driver now uses this to output the command results as you go, which makes the interface
more reactive seeming.

in the DWARF + debug map symbol file parser.

Also cleaned up the "image lookup --address ADDR" output when we it results
in something that is in an inlined function. Now we correctly dump out the
full inlined call stack.

lldb_private::Function objects. Previously the SymbolFileSymtab subclass
would return lldb_private::Symbol objects when it was asked to find functions.

The Module::FindFunctions (...) now take a boolean "bool include_symbols" so
that the module can track down functions and symbols, yet functions are found
by the SymbolFile plug-ins (through the SymbolVendor class), and symbols are
gotten through the ObjectFile plug-ins.

Fixed and issue where the DWARF parser might run into incomplete class member
function defintions which would make clang mad when we tried to make certain
member functions with invalid number of parameters (such as an operator=
operator that had no parameters). Now we just avoid and don't complete these
incomplete functions.

cases when getting the clang type:
- need only a forward declaration
- need a clang type that can be used for layout (members and args/return types)
- need a full clang type

This allows us to partially parse the clang types and be as lazy as possible.
The first case is when we just need to declare a type and we will complete it
later. The forward declaration happens only for class/union/structs and enums.
The layout type allows us to resolve the full clang type _except_ if we have
any modifiers on a pointer or reference (both R and L value). In this case
when we are adding members or function args or return types, we only need to
know how the type will be laid out and we can defer completing the pointee
type until we later need it. The last type means we need a full definition for
the clang type.

Did some renaming of some enumerations to get rid of the old "DC" prefix (which
stands for DebugCore which is no longer around).

Modified the clang namespace support to be almost ready to be fed to the
expression parser. I made a new ClangNamespaceDecl class that can carry around
the AST and the namespace decl so we can copy it into the expression AST. I
modified the symbol vendor and symbol file plug-ins to use this new class.

Make sure the address passed into SymbolContext::DumpStopContext() is valid before trying to calculate any offsets.

cleaning up the output of many GetDescription objects that are part of a 
symbol context. This fixes an issue where no ranges were being printed out
for functions, blocks and symbols.

parent, sibling and first child block, and access to the
inline function information.

Added an accessor the StackFrame:

	Block * lldb_private::StackFrame::GetFrameBlock();
	
LLDB represents inline functions as lexical blocks that have
inlined function information in them. The function above allows
us to easily get the top most lexical block that defines a stack
frame. When there are no inline functions in function, the block
returned ends up being the top most block for the function. When
the PC is in an inlined funciton for a frame, this will return the
first parent block that has inlined function information. The
other accessor: StackFrame::GetBlock() will return the deepest block
that matches the frame's PC value. Since most debuggers want to display
all variables in the current frame, the Block returned by
StackFrame::GetFrameBlock can be used to retrieve all variables for
the current frame.

Fixed the lldb_private::Block::DumpStopContext(...) to properly
display inline frames a block should display all of its inlined
functions. Prior to this fix, one of the call sites was being skipped.
This is a separate code path from the current default where inlined
functions get their own frames.

Fixed an issue where a block would always grab variables for any
child inline function blocks.
