In HOL4 you can do “set_trace "simplifier" 2;” (or an higher value) to
display information about how the term is being rewritten by simpLib (it
is a more general facility than “REWRITE_CONV”); with the GNU Emacs mode
you can use «M-h C-s» to toggle. There is also a facility
“used_rewrites” within simpLib (see “src/simp/src/simpLib.sig”).

In HOL Light I do not know if there is an equivalent.
