variables prior to running your binary. Zero filled sections now get
section data correctly filled with zeroes when Target::ReadMemory
reads from the object file section data.

Added new option groups and option values for file lists. I still need
to hook up all of the options to "target variable" to allow more complete
introspection by file and shlib.

Added the ability for ValueObjectVariable objects to be created with
only the target as the execution context. This allows them to be read
from the object files through Target::ReadMemory(...). 

Added a "virtual Module * GetModule()" function to the ValueObject
class. By default it will look to the parent variable object and
return its module. The module is needed when we have global variables
that have file addresses (virtual addresses that are specific to
module object files) and in turn allows global variables to be displayed
prior to running.

Removed all of the unused proxy object support that bit rotted in 
lldb_private::Value.

Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code
with the more efficient "FileSpec::Equal (lhs, rhs)".

Improved logging in GDB remote plug-in.

objective C or C++ methods when "self" or "this" were in scope, but had 
invalid locations in a DWARF location list. The lack of a valid value caused
us to use an invalid type value and then we tried to import that invalid

would return instead of a less than helpful "name: '%s'" description.

Make sure that when we ask for the error from a ValueObject object we
first update the value if needed.

Cleaned up some SB functions to use internal functions and not re-call
through the public API when possible.

instructions if they are conditional. Also fixed issues where the PC wasn't
getting bit zero stripped for ARM targets when a stack frame was thumb. We
now properly call through the GetOpcodeLoadAddress() functions to make sure
the addresses are properly stripped for any targets that may decorate up
their addresses.

We now don't pass the SIGSTOP signals along. We can revisit this soon, but
currently this was interfering with debugging some older ARM targets that
don't have vCont support in the GDB server.

Also, the previous logic in the GDB communication needs to watch for success
with an error so we can deal with EAGAIN and other normal "retry" error codes.

_only_ in the resulting stream, not in the error objects (lldb_private::Error).
lldb_private::Error objects should always just have an error string with no 
terminating newline characters or periods.

Fixed an issue with GDB remote packet detection that could end up deadlocking
if a full packet wasn't received in one chunk. Also modified the packet 
checking function to properly toss one or more bytes when it detects bad
data.

 - type names can now be regular expressions (exact matching is done first, and is faster)
 - integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them
 - array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays)
 - summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier
 - basic support for ObjectiveC:
  - ObjectiveC inheritance chains are now walked through
  - %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object
 - some bug fixes

This commit adds a new top subcommand "summary" to command type named "type". Currently this command
implements three commands:

type summary add <format> <typename1> [<typename2> ...]
type summary delete <typename1> [<typename2> ...]
type summary list [<typename1> [<typename2>] ...]
type summary clear

This allows you to specify the default format that will be used to display
summaries for variables, shown when you use "frame variable" or "expression", or the SBValue classes.

Examples:
type summary add "x = ${var.x}" Point

type summary list

type summary add --one-liner SimpleType

level in the public API. 

Also modified the ValueObject values to be able to display global variables
without having a valid running process. The globals will read themselves from
the object file section data if there is no process, and from the process if
there is one.

Also fixed an issue where modifications for dynamic types could cause child
values of ValueObjects to not show up if the value was unable to evaluate
itself (children of NULL pointer objects).

llvm-svn: 134102

Fixed crashes for SBValue fuzz calls.
And change 'bool SBType::IsPointerType(void)' to
'bool SBType::IsAPointerType(void)' to avoid name collision with the static 'bool SBType::IsPointerType(void *)'
function, which SWIG cannot handle.

two:

eOptionMarkPCSourceLine = (1u << 2), // Mark the source line that contains the current PC (mixed mode only)
eOptionMarkPCAddress    = (1u << 3)  // Mark the disassembly line the contains the PC

This allows mixed mode to show the line that contains the current PC, and it
allows us to mark the PC address in the disassembly if desired. Having these
be separate gives more control on the disassembly output. SBFrame::Disassemble()
doesn't enable any of these options.

inspection of namespaces in the expression parser.

ClangExpressionDeclMap hitherto reported that namespaces had
been completely imported, even though the namespaces are
returned empty.  To deal with this situation, ClangASTSource
was recently extended with an API to complete incomplete type
definitions, and, for greater efficiency, to complete these
definitions partially, returning only those objects that have
a given name.

This commit supports these APIs on LLDB's side, and uses it
to provide information on types resident in namespaces.
Namespaces are now imported as they were -- that is to say,
empty -- but with minimal import mode on.  This means that
Clang will come back and request their contents by name as
needed.  We now respond with information on the contained
types; this will be followed soon by information on functions
and variables.

the FormatManager class. Modified the format arguments in any commands to be
able to use a single character format, or a full format name, or a partial 
format name if no full format names match.

Modified any code that was displaying formats to use the new FormatManager
calls so that our help text and errors never get out of date.

Modified the display of the "type format list" command to be a bit more
human readable by showing the format as a format string rather than the single
character format char.

Added a fix for where you might have already displayed something with a given
type, then did a "type format add ...", then you display the type again. This
patch will figure out that the format changed and allow us to display the
type with the correct new format.

llvm-svn: 133743

This commit adds a new top level command named "type". Currently this command
implements three commands:

type format add <format> <typename1> [<typename2> ...]
type format delete <typename1> [<typename2> ...]
type format list [<typename1> [<typename2>] ...]

This allows you to specify the default format that will be used to display
types when you use "frame variable" or "expression", or the SBValue classes.

Examples:

// Format uint*_t as hex
type format add x uint16_t uint32_t uint64_t

// Format intptr_t as a pointer
type format add p intptr_t

The format characters are the same as "printf" for the most part with many
additions. These format character specifiers are also used in many other 
commands ("frame variable" for one). The current list of format characters
include:

a - char buffer
b - binary
B - boolean
c - char
C - printable char
d - signed decimal
e - float
f - float
g - float
i - signed decimal
I - complex integer
o - octal
O - OSType
p - pointer
s - c-string
u - unsigned decimal
x - hex
X - complex float
y - bytes
Y - bytes with ASCII
