From 0fa376e027f0bd71368e1485f863f0dff8f7c897 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 30 Jan 2008 13:30:55 +0100 Subject: [PATCH] x86: PTRACE_SINGLEBLOCK This adds the PTRACE_SINGLEBLOCK request on x86, matching the ia64 feature. The implementation comes from the generic ptrace code and relies on the low-level machine support provided by arch_has_block_step() et al.
