Bug ID: 52590
Summary: Unclear documentation
OS: Windows NT
Component: -New Bugs
Assignee: unassignedclangbugs at nondot.org

On https://clang.llvm.org/docs/UsersManual.html#id9 it mentions the following
command line options:
-gline-directives-only Emit debug line info directives only
-gline-tables-only Emit debug line number tables only
These options might be obvious if you have a thorough understanding of how
debug info is being stored. Though, I don't.
A quick google search for this doesn't give any helpful hints either:
My understanding from -gline-tables-only: Emit debug info that allows the
debugger to show the source code line linked to the stack frame. No information
about variables is available.
However, for the -gline-directives-only I don't understand what it does and
what the difference is with the other option.
Can this be clarified?
