Hi, I have seen that PowerPC mpc885 is not supported in Valgrind. I have modified some src files (m_transtab.c, m_machine.c, guest_ppc_toIR.c) for pass some assertion but I need to know how can add full support for this cpu into Valgrind. With this, other users can develop for this platform. What files I have to modify for support new cpu (powerPC architecture) into Valgrind? Can you help me for this? Best Regards. Alessandro Biasci |

New Revision: 11223
Log:
Add a fix equivalent to r10751 for amd64-darwin: Resync after
{wq,p}thread_hijack rather than merely doing a check. Also, some
whitespace changes that make it easier to diff by eye relative to the
x86-darwin versions. "Fixes" the problem reported at
