From cf855653b9d66300a2dfaff75c05753321b9c5cc Mon Sep 17 00:00:00 2001 From: foreman Date: Mon, 6 May 2019 17:20:00 -0400 Subject: [PATCH] P4 to Git Change 1778949 by michliao@hliao-dev-00-hip.rocm-workspace on 2019/05/06 16:36:53 SWDEV-144570 - Fix build failure after switching to gcc-7 - Hex representation of float needs gnu++11. We'd better not relying on that. Change the float in hex format into alternative representation.
