christos 9aa540a2b5 Add wrappers for the newly added functions. Thanks Klaus! 2005-07-21 16:58:39 +00:00
christos e5c18e58f2 Add log2 and log2f from FreeBSD PR 83845 2005-07-21 12:55:58 +00:00
jmmv 8740cbe236 Add a conditional for proper m68k softfloat operation. It looks like I 
forgot to commit this file back when this functionality was added.
Noted by Bruce O'Neel (the original author) in port-mac68k@.

junyoung bc836a3102 lib/24252: Add C99 functions round(3) and roundf(3). 
libm minor unchanged; ride a recent bump.

From FreeBSD.

drochner 07be12b505 also provide an alpha assembler implemtation of lrint() 2004-07-01 19:08:21 +00:00
drochner 5d151d763f enable lrint.S for amd64 (which doesn't build libm387), 
and tighten the generic->machdep source distribution a bit to avoid
unwanted substitutions
 2004-07-01 17:33:16 +00:00
drochner 147d852dbc being here, add the (l)lround(f) functions to libm 
(almost the same like lrint)
 2004-07-01 16:09:21 +00:00
drochner d76992e490 Implement (l)lrint(f). 
(Could get some optimization for LP64; this would need a change to
the float access macros in math_private.h.)

matt 0202d560cf Compile libm on VAX at WARNS=2; leave other architectures at WARNS=1 2002-06-15 00:13:07 +00:00
ross de50fe2e64 Drink ALL the Kool-Aid. 
(Move -mieee from lib/ to bsd.*.mk; new var MKIEEEFP defaults to yes.)

thorpej 4586df0992 On Alpha, build libc and libm with -mieee ... A metric crapload 
of 3rd party software expects this.

XXX TODO: consider libm-fast for alpha that is not -mieee.  Possibly
determine -mieee or not at run-time based on a bit in the executable
headers.

lukem efcc9a4c9d * Add user-controlled mk.conf variables 
- SHLIBDIR	Location to install shared libraries if ${USE_SHLIBDIR}
			is "yes".  Defaults to "/usr/lib".

	- USE_SHLIBDIR	If "yes", install shared libraries in ${SHLIBDIR}
			instead of ${LIBDIR}.  Defaults to "no".
			Sets ${_LIBSODIR} to the appropriate value.
			This may be set by individual Makefiles as well.

	- SHLINKDIR	Location of shared linker.  Defaults to "/usr/libexec".
			If != "/usr/libexec", change the dynamic-linker
			encoded in shared programs

* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
	libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
	libtermcap libutil libz

* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
  to ${_LIBSODIR}/${LIB}.so* for compatibility.

* Always install /sbin/init statically (for now)


The net effect of these changes depends on how the variables are set:

  1.)	If nothing is set or changed, there is no change from the
	current behaviour:
		- Static /bin, /sbin, and bits of /usr/*
		- Dynamic rest
		- Shared linker is /usr/libexec/ld*so

  2.)	If the following make variables are set:
		LDSTATIC=
		SHLINKDIR=/lib
		SHLIBDIR=/lib
	Then the behaviour becomes:
		- Dynamic tools
		- .so libraries used by /bin and /sbin are installed to /lib,
		  with symlinks from /usr/lib/lib*so to -> /lib/lib*so
		  where appropriate
		- Shared linker is /lib/ld*so

  3.)	As per 2.), but add the following variable:
		USE_SHLIBDIR=yes
	This forces all .so's to be instaleld in /lib (with compat
	symlinks), not just those tagged by their Makefiles to be.
	Again, compat symlinks are installed

kleink b3f30828b1 Document isinff(3) and isnanf(3), cloned from the corresponding double- 
precision manual page.  It is kept separately since the latter are part of
libc and thus impose different linkage instructions.

simonb 42724dd4d2 More trailing white space. 1999-07-02 15:37:33 +00:00
is 456bf68494 Quick and dirty hook to compile a non-6888[12] libm for 68040 and 68060. 
This is switched to by the M68040 or M68060 defines.
XXX Eventually, a M060SP based libm should be built for M68060.

ragge 9f749c2036 The Mariah chip lacks the POLYD instruction, so some assembly coded 
calculations must be done in C instead. Fast fix until the POLY{D,F,G,H}
insn's are written.

perry 3e3611d479 on i386, use FPU instructions in libm if I387_LIBM is set, from dan@geek.com.au 1998-08-09 23:51:33 +00:00

cgd 0924c4443d Make sure the reason that NOLINT is set is documented. Additionally 
in places where it should be set (or has to be set right now), do so.

jtc 593d18fc49 Added a ieee_test(3) man page (Like SunOS) derrived from an earlier copy
