New Revision: 349429
URL: http://llvm.org/viewvc/llvm-project?rev=349429&view=rev
Log:
Add "dump" command as a custom "process plugin" subcommand when ProcessMinidump is used.
Each process plug-in can create its own custom commands. I figured it would be nice to be able to dump things from the minidump file from the lldb command line, so I added the start of the some custom commands.
Currently you can dump:
minidump stream directory
all linux specifc streams, most of which are strings
each linux stream individually if desired, or all with --linux
The idea is we can expand the command set to dump more things, search for data in the core file, and much more. This patch gets us started.
