Author: abhishek Date: Thu Sep 8 07:22:56 2016 New Revision: 280924 URL: http://llvm.org/viewvc/llvm-project?rev=280924&view=rev Log: LLDB: API for iPermission of object file's sections Summary: - Added an API to public interface that provides permissions (RWX) of individual sections of an object file - Earlier, there was no way to find out this information through SB APIs - A possible use case of this API is: when a user wants to know the sections that have executable machine instructions and want to write a tool on top of LLDB based on this information
