-- 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

# 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
|
|
#
|
|
|
|
# Enable if you have a i387 (or i486 or Pentium)
