From 98a90c02792f22afd8161f96fc9b9f0f0eb0880e Mon Sep 17 00:00:00 2001 From: Renzo Davoli Date: Sun, 21 May 2006 20:06:58 +0200 Subject: [PATCH] powerpc: enable PPC_PTRACE_[GS]ETREGS on ppc32 I have tested PPC_PTRACE_GETREGS and PPC_PTRACE_SETREGS on umview. I do not understand why historically these tags has been defined as PPC_PTRACE_GETREGS and PPC_PTRACE_SETREGS instead of simply PTRACE_[GS]ETREGS. The other "originality" is that the address must be put into the "addr" field instead of the "data" field as stated in the manual.
