This file was already there, it was just not being used. I understand that this 'ifndef' might be confusing, though I decided to add it to mimic the behavior of the default sys/param.h. There is however an unrelated issue with this patch, a typo in the "#define NOFILE" that crept in there due to some copy pasting when splitting the patch. Here is a fixed version.

* or1k: Allow exception nestingJeff Johnston2015-08-074-39/+149
| | | | | | | | | | | | | | | | | | | Allow exceptions to be nested, which is especially useful with urgent interrupts while processing an exception. The implementation counts up the nesting level with each call to an exception. In the outer exception (level 1), the exception stack is started. All nested exceptions just reserve the redzone (scratch memory that may be used by compiler) and exception context on the stack, but then process on the same scratch. Restriction: Impure pointers are shared among all exceptions. This may be solved by creating an impure data structure in the stack frame with each nested exception. * or1k/crt0.S: Add exception nesting * or1k/exceptions-asm.S: ditto * or1k/util.c: ditto

* [AArch64] Rewrite optimized memset.Wilco Dijkstra2015-07-302-191/+188
| | | | | | | | | | | This is an optimized memset for AArch64. Memset is split into 4 main cases: small sets of up to 16 bytes, medium of 16..96 bytes which are fully unrolled. Large memsets of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. Memsets of zero of more than 256 use the dc zva instruction, and there are faster versions for the common ZVA sizes 64 or 128. STP of Q registers is used to reduce codesize without loss of performance.

* Move header filesSebastian Huber2015-07-299-5/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | During libgcc build the first include search path for <...> is "../newlib/libc/sys/rtems/include". Move all RTEMS specific header files to "libc/sys/rtems/include" so that they can be found. Later during libc build the header files in the previous location were somehow present, but for libgcc build they were invisible. This change is necessary to use <pthread.h> for the GCC thread model implementation. newlib/ChangeLog 2015-07-27 Sebastian Huber <sebastian.huber@embedded-brains.de> libc/sys/rtems/machine/_types.h: Move to ... libc/sys/rtems/include/machine/_types.h: ... here. libc/sys/rtems/machine/limits.h: Move to ... libc/sys/rtems/include/machine/limits.h: ... here. libc/sys/rtems/machine/param.h: Move to ... libc/sys/rtems/include/machine/param.h: ... here. libc/sys/rtems/sys/cpuset.h: Move to ... libc/sys/rtems/include/sys/cpuset.h: ... here. libc/sys/rtems/sys/dirent.h: Move to ... libc/sys/rtems/include/sys/dirent.h: ... here. libc/sys/rtems/sys/param.h: Move to ... libc/sys/rtems/include/sys/param.h: ... here. libc/sys/rtems/sys/syslimits.h: Move to ... libc/sys/rtems/include/sys/syslimits.h: ... here. libc/sys/rtems/sys/utime.h: Move to ... libc/sys/rtems/include/sys/utime.h: ... here.

| | | | | | | | | | | | | | | | | | | | | | | | | | We use texinfo nodes beginning with an underscore in several other places, so revert this ancient workaround for a no longer existing bug, and use the makedoc generated texinfo for reentrant versions of syscalls, rather than handwritten documentation. Also alphabetically sort these functions. Also add documentation for _execve_r, _getpid_r, _kill_r and _times_r functions, whose non-reentrant versions are documented as stubs v2: Keep _open64_r, _lseek64_r and _fstat64_r functions under texinfo conditional STDIO64 Add _stat64_r function likewise. Notes: 1. The handwritten prototypes give the reentrancy structure pointer as of type void *, rather than the presumably more correct struct __reent * 2. The fcntl, gettimeofday, mkdir and rename functions are not documented as stubs, so I haven't added the reentrant versions either Signed-off-by: Jon TURNEY <jon.turney@dronecode.org.uk>
