Hi Jennifer and I have a series of changes pending to RTEMS that add cpuset tests, pthread affinity APIs and Classic API affinity APIs. These depend on the presence of certain prototypes and data types in newlib.
In an attempt to keep things building with old tools, I have attached a set of patches that I think can be used to detect enough of the changes to let git bisect continue to work across the tool changes. For sure, our (unmerged) code will have to use the proper conditionals to prevent itself from being compiled. The one I don't know about it Sebastian's re-implementation of pthread cleanup push/pop. I don't know how to detect that change. How do these patches look? And any suggestions? The changes to newlib are on the cvs head -- pthread.h and cpuset.h primarily. -- Joel Sherrill, Ph.D. Director of Research & Development joel.sherr...@oarcorp.com On-Line Applications Research Ask me about RTEMS: a free RTOS Huntsville AL 35805 Support Available (256) 722-9985
