Johnny Chen 1cd81bf9e5 Fix typos in comment. 
llvm-svn: 138179
 2011-08-20 01:02:31 +00:00
Johnny Chen 8fff33615d Use os.walk(), available since 2.3, instead of os.path.walk(), removed in 3.0, 
to walk the directory tree.  Plus, we can concentrate only on leaf nodes, i.e., files.

Johnny Chen 20f19d1d02 No need to look further if the file is a symbolic link. Look for the real file. 
Plus add some comments.

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 4c35b711da Fix TypeError exception for re.compile(). 
llvm-svn: 138045
 2011-08-19 17:28:25 +00:00
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 8831e18b17 Make 'run-until-faulted.py' script more interesting by modifying the example main.c program 
to seg fault randomly instead of deterministically.

Johnny Chen b5aa97ecc5 Add a Python utility to help convert the Mail.app saved 'Raw Message Source' .eml file to a git-am friendly file. 
llvm-svn: 131924
 2011-05-23 21:50:12 +00:00
Johnny Chen 6cd4d1d85a Modified to take advantage of the iteration protocol for our lldb container objects. 
llvm-svn: 130457
 2011-04-28 23:34:58 +00:00
Johnny Chen 511e8c0d36 Add a Python script which launches a program from within lldb and loop until the 
process stops for some reason.  main.c (compiled into a.out) is used as an example in
the README-run-until-faulted file.

llvm-svn: 128755
 2011-04-02 01:20:28 +00:00
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.

llvm-svn: 128604
 2011-03-31 01:34:55 +00:00
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.

llvm-svn: 128601
 2011-03-31 01:06:28 +00:00
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

llvm-svn: 128569
 2011-03-30 18:47:54 +00:00
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 4044fdccfc Doc string change. 
llvm-svn: 128429
 2011-03-28 22:48:25 +00:00
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.

llvm-svn: 128428
 2011-03-28 22:40:32 +00:00
Johnny Chen 9d46337511 Add options to allow for specifying an option string when spawning gdb and for executing 
command(s) right after starting up gdb.  Update the README file to show an example of
using these to pass '-arch armv7' to gdb and to execute gdb command to set shared library
path substitutions before loading iOS4.3 sdk's /usr/lib/libSystem.B.dylib and disassembling
the 'printf' function.

Johnny Chen 5c07daaa1d Modify disasm.py to better deal with the objc method name which has ':' in them. 
Add a utility similar to disasm.py, but which provides a shell-like environment for invoking llvm-mc.

Johnny Chen 0d825132c6 Tidy up the input file given to 'llvm-mc -disassemble' and also append the gdb 
assembler code to the memory dump.

llvm-svn: 127823
 2011-03-17 19:05:34 +00:00
Johnny Chen 6f6fb3e515 Add a Python script to take an executable, run gdb to disassemble a function, 
read the memory contents of the function, and then feed the bytes to the
'llvm-mc -disassemble' command.

It uses the pexpect module located under ToT/test/pexpect-2.4 directory to
automate the interaction with gdb.  This is used initially to test the low
level ARM disassembler of llvm.

llvm-svn: 127785
 2011-03-17 00:59:57 +00:00
Johnny Chen 43b3bad58b Initial check-in of a Python utility to run the lldb test suite and send the 
result including the session logs of test failures/errors as a MIME message.
