freebsd-skq/lib/msun/Makefile
Bruce Evans dab159e3d6 Select between the generic math functions and the i387-specific ones
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.

# There are two options in making libm at fdlibm compile time:
# _IEEE_LIBM --- IEEE libm; smaller, and somewhat faster
# _MULTI_LIBM --- Support multi-standard at runtime by
# imposing wrapper functions defined in
# fdlibm.h:
# _IEEE_MODE -- IEEE
# _XOPEN_MODE -- X/OPEN
# _POSIX_MODE -- POSIX/ANSI
# _SVID3_MODE -- SVID
#
# Here is how to set up CFLAGS to create the desired libm at
# compile time:
#
# CFLAGS = -D_IEEE_LIBM ... IEEE libm (recommended)
# CFLAGS = -D_SVID3_MODE ... Multi-standard supported
# libm with SVID as the
# default standard
# CFLAGS = -D_XOPEN_MODE ... Multi-standard supported
# libm with XOPEN as the
# default standard
# CFLAGS = -D_POSIX_MODE ... Multi-standard supported
# libm with POSIX as the
# default standard
# CFLAGS = ... Multi-standard supported
# libm with IEEE as the
# default standard
