From cb67e161bc947ab467657dda38168c2b2266f5bc Mon Sep 17 00:00:00 2001 From: Chris Metcalf Date: Wed, 12 Dec 2012 17:24:39 -0500 Subject: arch/tile: provide PT_FLAGS_COMPAT value in pt_regs This flag is set for ptrace GETREGS or PEEKUSER for processes that are COMPAT, i.e. 32-bit. This allows things like strace to easily discover what personality to use, for example.
