From 9fa55373e1c27f2e5f3f2e0643040049b4243c05 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 25 Mar 2015 21:21:18 +0000 Subject: [PATCH] Remove unused macros from i386 lowlevellock.h. In the course of the work on six-argument syscalls I noticed that the i386 lowlevellock.h contained some unused macro definitions (already unused before my patch). This patch removes them. Tested for x86 that installed stripped shared libraries are unchanged by this patch. * sysdeps/unix/sysv/linux/i386/lowlevellock.h (LLL_EBX_LOAD): Remove macro. (LLL_EBX_REG): Likewise.
