spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

libc: further adoption of SPDX licensing ID tags. Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

Add an alternative view of the bits in an 80-bit long double (64+16 instead of 32+32+15+1) on all arches that have such long doubles (amd64, ia64 and i386). Large objects should be be accessed in large units, and the 32+32+15+1[+padding] decomposition asks for almost the opposite of that, sometimes resulting in very slow accesses depending on how well the compiler ignores what we ask for and converts to the best units for the given machine. E.g., on Athlons, there is a 10-20 cycle penalty for accessing the middle 32-bit word immediately after an 80-bit store. Whether actually using the alternative view is better is very machine- dependent. A 32+32+16 view is probably best with old 32-bit systems and gcc through 4.2.1. The compiler should mostly avoid the view and generate best accesses, but gcc-4.2.1 is far from doing that. I think 64+16 is best for now. Similarly for doubles -- they should be using 64+0 especially on 64-bit machines, but fdlibm uses 32+32 extensively for them. Fortunately, in 64-bit mode for doubles, gcc already ignores the 32+32-bit view and generates best accesses in many cases.

Define LDBL_NBIT to be a mask indicating the position of the integer bit in a long double. For architectures that don't have such a bit, LDBL_NBIT is 0. This makes it possible to say `mantissa & ~LDBL_NBIT' in places that previously used an #ifdef to select the right expression. The optimizer should dispense with the extra arithmetic when LDBL_NBIT is 0.

Implement fpclassify(): o Add a MD header private to libc called _fpmath.h; this header contains bitfield layouts of MD floating-point types. o Add a MI header private to libc called fpmath.h; this header contains bitfield layouts of MI floating-point types. o Add private libc variables to lib/libc/$arch/gen/infinity.c for storing NaN values. o Add __double_t and __float_t to <machine/_types.h>, and provide double_t and float_t typedefs in <math.h>. o Add some C99 manifest constants (FP_ILOGB0, FP_ILOGBNAN, HUGE_VALF, HUGE_VALL, INFINITY, NAN, and return values for fpclassify()) to <math.h> and others (FLT_EVAL_METHOD, DECIMAL_DIG) to <float.h> via <machine/float.h>. o Add C99 macro fpclassify() which calls __fpclassify{d,f,l}() based on the size of its argument. __fpclassifyl() is never called on alpha because (sizeof(long double) == sizeof(double)), which is good since __fpclassifyl() can't deal with such a small `long double'. This was developed by David Schultz and myself with input from bde and fenner.
