…on start It can happen that a line entry reports that some source code is located at line 0. In DWARF, line 0 is a special location which indicates that code has no 1-1 mapping with source. When stopping in one of those artificial locations, lldb doesn't know which line to display and shows the beginning of the file instead. This patch mitigates this behaviour by checking if the current symbol context of the line entry has a matching function, in which case, it slides the source listing to the start of that function. This patch also shows the user a warning explaining why lldb couldn't show sources at that location. rdar://83118425 Differential Revision: https://reviews.llvm.org/D115313 Signed-off-by: Med Ismail Bennani <[email protected]>
