I don't see open pull requests in https://github.com/ARM-software/optimized-routines/pulls What is the status with respect to a Newlib integration? All the necessary changes have been integrated into the optimized-routines repository. I just pinged the newlib list about integrating those changes since there doesn't seem to have been any movement toward that goal.

I just rebuilt this on the current RTEMS6 GCC10 branch with current newlib (ed32020) and had no problems building it. It's odd that the file is missing given that it's newly written by the patch. What else is necessary to reproduce the build failure? Kinsey ___ devel mailing list devel@rtems.org http://lists.rtems.org/mailman/listinfo/devel
