Subject: [PATCH v9 4/4] selftests/powerpc: update strlen() test to test the new assembly function for PPC32
Date: Thu,  2 Aug 2018 08:26:32 +0000 (UTC)	[thread overview]
Message-ID: <3193a73d4b251d25e6c10cd1e875a450de50a7e6.1533198182.git.christophe.leroy@c-s.fr> (raw)

This patch adds a test for testing the new assembly strlen() for PPC32

Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
---
 v9: fixed relevant checkpatch warnings
 v8: removed defines in ppc_asm.h that were added in v6 (not used anymore since v7) ; added missing link to strlen_32.S
 v7: reduced the scope to PPC32
 v6: added additional necessary defines in ppc_asm.h
 v5: no change
 v4: new
