New Revision: 137988
URL: http://llvm.org/viewvc/llvm-project?rev=137988&view=rev
Log:
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
