Cleanup the StackTrace interfaces and profile interfaces so they are more efficient and reduce the number of new/delete calls arch/alpha/stacktrace.cc: - Change the StackTrace code so that the class can more easily be cleaned out and reused to avoid extra allocations. - Allow trace() to accept a static instruction pointer so it can determine if the instruction is worth tracing. This is moved from the CPU. - provide constants for special meaning PCs (user, console, unknown), instead of magic numbers - switch to using kernelSymtab instead of allSymtab which will be going away - if the stack adjustment doesn't make any sense, exit and push unknown so we don't get into an infinite loop or record garbage. - check to see if we've made too many iterations through the stack and panic to avoid an infinite loop arch/alpha/stacktrace.hh: - Change the StackTrace code so that the class can more easily be cleaned out and reused to avoid extra allocations. - Allow trace() to accept a static instruction pointer so it can determine if the instruction is worth tracing.
