Fix to solve Bug 23139 & Bug 23560
Summary: - Reason of both bugs: 1. For the very first frame, Unwinder doesn't check the validity of Full UnwindPlan before creating StackFrame from it: When 'process launch' command is run after setting a breakpoint in inferior, the Unwinder runs and saves only Frame 0 (the frame in which breakpoint was set) in thread's StackFrameList i.e. m_curr_frames_sp. However, it doesn't check the validity of the Full UnwindPlan for this frame by unwinding 2 more frames further. 2. Unwinder doesn't update the CFA value of Cursor when Full UnwindPlan fails and FallBack UnwindPlan succeeds in providing valid CFA values for frames: Sometimes during unwinding of stack frames, the Full UnwindPlan inside the RegisterContextLLDB object may fail to provide valid CFA values for these frames. Then the Fallback UnwindPlan is used to unwind the frames. If the Fallback UnwindPlan succeeds, then it provides a valid new CFA value. The RegisterContextLLDB::m_cfa field of Cursor object is updated during the Fallback UnwindPlan execution. However, UnwindLLDB misses the implementation to update the 'cfa' field of this Cursor with this valid new CFA value. - This patch fixes both these issues. - Remove XFAIL in test files corresponding to these 2 Bugs Change-Id: I932ea407545ceee2d628f946ecc61a4806d4cc86 Signed-off-by: Abhishek Aggarwal <abhishek.a.aggarwal@intel.com> Reviewers: jingham, lldb-commits, jasonmolenda Subscribers: lldb-commits, ovyalov, tberghammer Differential Revision: http://reviews.llvm.org/D14226 llvm-svn: 253026
