1.9	03-Mar-2014	dsl	Drop in a fabs() after the fsqrt(). While it may seem pointless, it the rouding mode is set to round towards minus infinity then acos(-1) calculates atan2(sqrt(1.0 - 1.0), -1) the subtract generates -0.0 which sqrt() preserves. atan2(-0, -1) is -pi, but acos(-1) is expected to be +pi. This might 'fix' the test failures seen in some environments, but they are not failing due to an obvously incorrent x87 rounding mode.
1.8	26-Jul-2003	salo	branches: 1.8.54; 1.8.60; netbsd.org->NetBSD.org
1.7	19-Jun-2001	fvdl	Modify the i387 code so that it can be shared between the i386 port and the x86_64 port. XXX some files should be distinct.
1.6	26-Sep-2000	kleink	Make these idempotent as far as the FPU register stack is concerned.
1.5	02-Jul-1999	simonb	branches: 1.5.8; More trailing white space.
1.4	08-May-1995	jtc	Id -> NetBSD
1.3	28-Apr-1995	jtc	Winning Strategies has placed this code into the Public Domain
1.2	12-Mar-1994	jtc	Added RCS ID's. ID's use new RCSID macro from <machine/asm.h>.
1.1	11-Feb-1994	jtc	FPU specific math code.
1.5.8.1	26-Sep-2000	kleink	Pull up rev. 1.6 (approved by thorpej): Make these idempotent as far as the FPU register stack is concerned.
1.8.60.1	20-Aug-2014	tls	Rebase to HEAD as of a few days ago.
1.8.54.1	22-May-2014	yamt	sync with head. for a reference, the tree before this commit was tagged as yamt-pagecache-tag8. this commit was splitted into small chunks to avoid a limitation of cvs. ("Protocol error: too many arguments")
