From: Pierre-Emmanuel Patry <[email protected]>
This data structure is complex, when using the debug dump within a
debugger we often need to know what is the current state and where new
nodes will be pushed within the forever stack.
gcc/rust/ChangeLog:
* resolve/rust-forever-stack.hxx: Debug the forever stack cursor
position.
Signed-off-by: Pierre-Emmanuel Patry <[email protected]>
Tested on x86_64-pc-linux-gnu.
