Johnny Chen 758f288cdd Add a Python script to locate each binary file under a root directory which matches some pathname pattern 
and to invoke lldb-disasm.py on the binary file to disassemble its symbols.  The number of symbols can
be specified by, for example, '-n 10000', to specify 10,000 symbols to disassemble for each module.
By default, only 1000 symbols from each module are disassembled.

Example:

utils/test/run-dis.py -r '/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3/Symbols' -p '^/System/Library/.*Frameworks/.*\.framework/[^/]+$'

tries to disassemble every public/private frameworks (by default only 1000 symbols are disassembled) under iOS4.3.

Johnny Chen 293683b6c4 Add an option (-p regexp-pattern) to specify the regular expression symbol pattern we're interested in disassembling. 
An example:

utils/test/lldb-disasm.py -C "platform select remote-ios" -o "-b -n" -e '~/CoreFoundation' -n 20 -p '-\[NSArray .+\]'

disassembles the first 20 NSArray instance methods found in the CoreFoundation module.

Johnny Chen 901209dcca Add an option '-q' to have quiet disassembly by not printing out the disassembled result. 
This could be useful by reducing the strain on standard output.

Example:

utils/test/lldb-disasm.py -C "platform select remote-ios" -o "-b -n" -e '~/CoreFoundation' -n 50 -q

Johnny Chen d16c105c3d Take advantage of the newly added SBSymbol.GetType() API to check whether we 
have a Code symbol and do disassembly on it.

Johnny Chen 0e43f321b6 Add a generator to iterate through the code symbols for a given target. 
To be modified to take advantage of the new SBSymbol API which checks a symbol for its type.

Johnny Chen 318e7ba65d Add an option to specify the symbols to disassemble instead of the existing 'num of symbols to disassemble' 
option.  If both are present, the 'symbols to disassemble' overrides the 'num of symbols to disassemble'.

An example usage:

$ ./lldb-disasm.py -C 'platform create remote-ios' -e /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/lib/libSystem.B.dylib -o '-r -n' -s vprintf -s acosf_special

Johnny Chen 6454e15f49 Add the ability to invoke lldb's disassemble command on the symbols digested from 
the 'image dump symtab' command.  The number of symbols to disassemble can be
specified by the '-n Num' option, or unlimited if not specified.

Johnny Chen 5e28aa5d9b Add an initial version of lldb-disasm.py script whose purpose is to iterate through 
all the symbols for an executable image and to issue the lldb 'disassemble' command
on each symbol.  The initial version just dumps the symbol table.
