[PATCH] D62423: [globalisel][legalizer] Attempt to write down the minimal legalization rules

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/docs/GlobalISel.rst:464-465
+
+There are no minimum rules for pointers since G_INTTOPTR and G_PTRTOINT can
+be lowered to COPY (or to nothing using replaceAllUses()) by the legalizer.

This should also probably say "selected" to copy, since IIRC COPY is not allowed to convert the type with generic virtual registers
