| | | | | | | | | | | do not also provide a __generic_XXX version as well. This is how we used to runtime select the generic vs i387 versions on the i386 platform. This saves a pile of #defines in the src/math_private.h file to undo the __generic_XXX renames in some of the *.c files. Notes: svn path=/head/; revision=117912

* Select between the generic math functions and the i387-specific onesBruce Evans1997-02-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | at runtime. etc/make.conf: Nuked HAVE_FPU option. lib/msun/Makefile: Always build the i387 objects. Copy the i387 source files at build time so that the i387 objects have different names. This is simpler than renaming the files in the cvs repository or repeating half of bsd.lib.mk to add explicit rules. lib/msun/src/*.c: Renamed all functions that have an i387-specific version by adding `__generic_' to their names. lib/msun/src/get_hw_float.c: New file for getting machdep.hw_float from the kernel. sys/i386/include/asmacros.h: Abuse the ENTRY() macro to generate jump vectors and associated code. This works much like PIC PLT dynamic initialization. The PIC case is messy. The old i387 entry points are renamed. Renaming is easier here because the names are given by macro expansions.

* Make the long-awaited change from $Id$ to $FreeBSD$Jordan K. Hubbard1997-01-141-1/+1
| | | | | | | | | | | 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. Notes: svn path=/head/; revision=21673

* J.T. Conklin's latest version of the Sun math library.Jordan K. Hubbard1994-08-191-0/+120
-- 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 Notes: svn path=/cvs2svn/branches/msun/; revision=2116
