New Revision: 138078
URL: http://llvm.org/viewvc/llvm-project?rev=138078&view=rev
Log:
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.
