From ba927e5dc148462a7cf80790495a5c40cb768bca Mon Sep 17 00:00:00 2001 From: Timothy McDaniel Date: Sun, 1 Nov 2020 17:29:57 -0600 Subject: [PATCH] event/dlb: add inline functions Add miscellaneous inline functions that may be called from multiple files. These functions include inline assembly of new x86 instructions, such as movdir64b, since they are not available as builtin functions in the minimum supported GCC version.
