(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
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
