In fact, I recently tested 3.13p for the PowerPC and posted ACATS results to the RTEMS users list. They were quite good. The sparc results were also good although the sparc backend now makes some Solaris dependent calls. :( We made RPMs available for GNAT/RTEMS 3.13p targetting the PowerPC and they are at ... ftp://ftp.oarcorp.com/pub/rtems/snapshots/ada_tools/gnat-3.13p-2 These support the latest development snapshots of RTEMS. > Simon. > > PS: I am not associated with OARcorp in any way apart from wanting to use > Ada with RTEMS... And although I AM associated with OARcorp, I personally I want to see Ada and RTEMS work together also. :) -- Joel Sherrill, Ph.D. Director of Research & Development joel@OARcorp.com On-Line Applications Research Ask me about RTEMS: a free RTOS Huntsville AL 35805 Support Available (256) 722-9985
