SourceView. * Fixed the information flow problem in Architecture::CreateStackTrace()/ ArchitectureX86::UpdateStackCpuState() by introducing a virtual UpdateStackFrameCpuState() which allows the architecture to update the CPU state it generated before after the function the state belongs to is known. That's where moving the instruction pointer to the previous instruction happens now. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31229 a95241bf-73f2-0310-859d-f6bbb57e9c96
