s-osinte-posix.adb, [...] (To_Target_Priority): New function maps from System.Any_Priority to a POSIX priority on the target.
2006-10-31 Arnaud Charlet <charlet@adacore.com> Jose Ruiz <ruiz@adacore.com> * s-osinte-posix.adb, s-osinte-linux.ads, s-osinte-freebsd.adb, s-osinte-freebsd.ads, s-osinte-solaris-posix.ads, s-osinte-hpux.ads, s-osinte-darwin.adb, s-osinte-darwin.ads, s-osinte-lynxos-3.ads, s-osinte-lynxos-3.adb (To_Target_Priority): New function maps from System.Any_Priority to a POSIX priority on the target. * system-linux-ia64.ads: Extend range of Priority types on Linux to use the whole range made available by the system. * s-osinte-aix.adb, s-osinte-aix.ads (To_Target_Priority): New function maps from System.Any_Priority to a POSIX priority on the target. (PTHREAD_PRIO_PROTECT): Set real value. (PTHREAD_PRIO_INHERIT): Now a function. (SIGCPUFAIL): New signal. (Reserved): Add SIGALRM1, SIGWAITING, SIGCPUFAIL, since these signals are documented as reserved by the OS. * system-aix.ads: Use the full range of priorities provided by the system on AIX. * s-taprop-posix.adb: Call new function To_Target_Priority. (Set_Priority): Take into account Task_Dispatching_Policy and Priority_Specific_Dispatching pragmas when determining if Round Robin must be used for scheduling the task. * system-linux-x86_64.ads, system-linux-x86.ads, system-linux-ppc.ads: Extend range of Priority types on Linux to use the whole range made available by the system. * s-taprop-vms.adb, s-taprop-mingw.adb, s-taprop-irix.adb, s-taprop-tru64.adb, s-taprop-linux.adb, s-taprop-hpux-dce.adb, s-taprop-lynxos.adb (Finalize_TCB): invalidate the stack-check cache when deallocating the TCB in order to avoid potential references to deallocated data. (Set_Priority): Take into account Task_Dispatching_Policy and Priority_Specific_Dispatching pragmas when determining if Round Robin or FIFO within priorities must be used for scheduling the task. * s-taprop-vxworks.adb (Enter_Task): Store the user-level task id in the Thread field (to be used internally by the run-time system) and the kernel-level task id in the LWP field (to be used by the debugger). (Create_Task): Reorganize to unify the calls to taskSpawn into a single instance, and propagate the current task options to the spawned task. (Set_Priority): Take into account Priority_Specific_Dispatching pragmas. (Initialize): Set Round Robin dispatching when the corresponding pragma is in effect. From-SVN: r118235
