From d3e036dfed74f9669d87b98bb0eff6338d3ac7b7 Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Wed, 10 Jun 2015 06:07:25 -0400 Subject: [PATCH 10/16] Add hash-map-tests.c Jeff approved an earlier version of this (as unittests/test-hash-map.c): https://gcc.gnu.org/ml/gcc-patches/2015-10/msg03301.html > OK if/when prereqs are approved. Minor twiddling if we end up > moving it elsewhere or standardizing/reducing header files is > pre-approved.
