Bug ID: 28293
Summary: LLDB can't find split debug info if the debuggee has
been moved form build directory
Product: lldb
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: vadi...@gmail.com
CC: llvm-b...@lists.llvm.org
Classification: Unclassified
(This situation often arises when build servers are employed)
I think this happens because LLDB simply takes DW_AT_comp_dir at the face value
here:
https://github.com/llvm-mirror/lldb/blob/876d71dc6c37f23c8ae9d219705d06c6def3f354/source/Plugins/SymbolFile/DWARF/SymbolFileDWARF.cpp#L1778-1794
There should be a way to remap debug info paths similarly to what is done for
source with 'target.source-map'. I would even argue that it should be the same
setting for both.
Another good candidate seems to be the 'target.debug-file-search-paths'
setting. LLDB could probe each of these directories (also probably the
directory where the debuggee is located) combined with the value of
DW_AT_GNU_dwo_name.
