1496870 - Add a GDB pretty-printer for mozilla::EnumSet

Status: RESOLVED FIXED

(Firefox Build System :: General, enhancement)

[Botond Ballo [:botond]]

After we transitioned the bitfield-style enum CompositorHitTestInfo to use mozilla::EnumSet in bug 1420996, it has come to my attention that EnumSet isn't very easy to work with in a debugger, in that determining the set of individual enumerator values that contribute to an EnumSet value can be laborious.

To make this better, I wrote a GDB pretty-printer for EnumSet.

Example output for a CompositorHitTestInfo:

(gdb) p hitResult
$5 = mozilla::gfx::CompositorHitTestInfo = {mozilla::gfx::CompositorHitTestFlags::eVisibleToHitTest, mozilla::gfx::CompositorHitTestFlags::eScrollbar, 
  mozilla::gfx::CompositorHitTestFlags::eScrollbarThumb, mozilla::gfx::CompositorHitTestFlags::eScrollbarVertical}
