From b2cb71e95e146724df93df8d3724f4d0475dcd54 Mon Sep 17 00:00:00 2001 From: Anatoly Burakov Date: Fri, 21 Dec 2018 11:29:03 +0000 Subject: [PATCH] test/mem: check non-heap external memory API Currently, extmem autotest only covers the external malloc heap API. Extend it to also cover the non-heap, register/unregister external memory API.
