[pushed] Report supportsBreakpointLocationsRequest
Checks
Commit Message
While looking at the DAP spec, I noticed that the breakpointLocations
request is gated behind a capability. This patch changes gdb to
report this capability.
I've also added a comment to explain the fact that arguments to
breakpointLocations are not optional, even though the spec says they
are.
