From c032524f0ddea5fcc3a2cece0d4a61f37e5ca9cd Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Fri, 28 Oct 2005 22:48:08 +1000 Subject: powerpc: Make single-stepping emulation (mostly) usable on 32-bit The sc instruction emulation can't be done the same way on 32-bit as 64-bit yet, but this should work OK.
