From f666ad413db6f7fbfaeec6b11ed6f8e4b60dda38 Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Fri, 30 Sep 2016 10:32:52 +0800 Subject: selftests/powerpc: Add ptrace tests for GPR/FPR registers This patch adds ptrace interface test for GPR/FPR registers. This adds ptrace interface based helper functions related to GPR/FPR access and some assembly helper functions related to GPR/FPR registers.
