From 5379ef2a60431232b9bb01c6d3580b875123d723 Mon Sep 17 00:00:00 2001 From: Nicholas Piggin Date: Fri, 3 Sep 2021 22:57:07 +1000 Subject: selftests/powerpc: Add scv versions of the basic TM syscall tests The basic TM vs syscall test code hard codes an sc instruction for the system call, which fails to cover scv even when the userspace libc has support for it. Duplicate the tests with hard coded scv variants so both are tested when possible.

As a result "make kselftest-clean" and "make clean" fail to remove executables. Run and install work because the common framework runs and installs TEST_PROGS.
