documented naming scheme (unfortunately the documentation isn't in the tree as far as I can tell); no repocopy is required as there is no history to preserve. - replace simple and almost-correct implementation with slightly hackish but definitely correct implementation (tested on i386, alpha, sparc64) which requires pulling in fpmath.h and the MD _fpmath.h from libc. - try not to make a mess of the Makefile in the process. - enterprising minds are encouraged to implement more C99 long double functions.

# 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
|
|
# math.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
