Proposed resolution (approved by CWG 2023-05-12):

Change in 7.6.7 [expr.shift] paragraph 3 as follows:

The value of E1 >> E2 is E1/2E2, rounded down towards negative infinity.

[Accepted as a DR at the June, 2023 meeting.]

(From editorial issue 6225.)

Subclause 7.6.7 [expr.shift] paragraph 3 specifies:

The value of E1 >> E2 is E1/2E2, rounded down.

It is unclear whether "rounded down" means "towards zero" or "towards negative infinity".
