Update scalbn* functions to the musl versions The only diff compared to musl is a minor change to scalbnl() to replace musl's union ldshape with union IEEEl2bits. This fixes the scalbn tests on non-x86 (since x86 has an assembly version that is used instead). Musl commit messages: commit 8c44a060243f04283ca68dad199aab90336141db Author: Szabolcs Nagy <nsz@port70.net> Date: Mon Apr 3 02:38:13 2017 +0200 fix scalbn when result is in the subnormal range in nearest rounding mode scalbn could introduce double rounding error when an intermediate value and the final result were both in the subnormal range e.g. scalbn(0x1.7ffffffffffffp-1, -1073) returned 0x1p-1073 instead of 0x1p-1074, because the intermediate computation got rounded to 0x1.8p-1023. with the fix an intermediate value can only be in the subnormal range if the final result is 0 which is correct even after double rounding. (there still can be two roundings so signals may be raised twice, but that's only observable with trapping exceptions which is not supported.) commit 2eaed464e2080d8321d3903b71086a1ecfc4ee4a Author: Szabolcs Nagy <nsz@port70.net> Date: Wed Sep 4 15:52:54 2013 +0000 math: use float_t and double_t in scalbnf and scalbn remove STRICT_ASSIGN (c99 semantics is assumed) and use the conventional union to prepare the scaling factor (so libm.h is no longer needed) commit 1b77b9072f374bd26eb0574b83a0d5f18d75ec60 Author: Szabolcs Nagy <nsz@port70.net> Date: Thu Aug 15 10:07:46 2013 +0000 math: minor scalbn*.c simplification commit c4359e01303da2755fe7e8033826b132eb3659b1 Author: Szabolcs Nagy <nsz@port70.net> Date: Tue Nov 13 10:55:35 2012 +0100 math: excess precision fix modf, modff, scalbn, scalbnf old code was correct only if the result was stored (without the excess precision) or musl was compiled with -ffloat-store. now we use STRICT_ASSIGN to work around the issue.

(scalbn(0x1p+1023,-2097) should give 0x1p-1074, but the old code gave 0) Reviewed By: dim Differential Revision: https://reviews.freebsd.org/D28872

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.

Fix formatting, this is hard to explain, so I'll show one example. - float ynf(int n, float x) /* wrapper ynf */ +float +ynf(int n, float x) /* wrapper ynf */ This is because the __STDC__ stuff was indented. Reviewed by: md5

Make the long-awaited change from $Id$ to $FreeBSD$ This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

J.T. Conklin's latest version of the Sun math library. -- Begin comments from J.T. Conklin: The most significant improvement is the addition of "float" versions of the math functions that take float arguments, return floats, and do all operations in floating point. This doesn't help (performance) much on the i386, but they are still nice to have. The float versions were orginally done by Cygnus' Ian Taylor when fdlibm was integrated into the libm we support for embedded systems. I gave Ian a copy of my libm as a starting point since I had already fixed a lot of bugs & problems in Sun's original code. After he was done, I cleaned it up a bit and integrated the changes back into my libm. -- End comments Reviewed by: jkh Submitted by: jtc
