From dd21731022faf43c1250050e5d28d11add599149 Mon Sep 17 00:00:00 2001 From: Lennart Sorensen Date: Thu, 5 May 2016 16:44:44 -0400 Subject: [PATCH] powerpc/sstep: Fix sstep.c compile on powerpcspe Commit be96f63375a1 ("powerpc: Split out instruction analysis part of emulate_step()") introduced ldarx and stdcx into the instructions in sstep.c, which are not accepted by the assembler on powerpcspe, but does seem to be accepted by the normal powerpc assembler even in 32 bit mode. Wrap these two instructions in a __powerpc64__ check like it is everywhere else in the file.
