Mark internal gmp functions with attribute_hidden [BZ #18822]

2017-10-01T22:15:30+00:00

Mark internal gmp functions with attribute_hidden to allow direct
access within libc.so and libc.a without using GOT nor PLT.

	[BZ #18822]
	* include/gmp.h: Declare internal functions only if _ISOMAC is
	undefined.
	(__mpn_extract_double): Add attribute_hidden.
	(__mpn_extract_long_double): Likewise.
	(__mpn_extract_float128): Likewise.

float128: Add conversion from float128 to mpn

2017-06-07T20:03:43+00:00

Reuse the code for __mpn_extract_long_double to implement
__mpn_extract_float128.

	* include/gmp.h: Include bits/floatn.h
	(__mpn_extract_float128): Declare when __HAVE_DISTINCT_FLOAT128 is 1.
	* stdlib/gmp-impl.h: Also check if alloca is not defined before
	including stack-alloc.h.  It could have been defined by other header
	which not necessarily defines HAVE_ALLOCA.
	* sysdeps/ieee754/float128/Makefile: New file.
	* sysdeps/ieee754/float128/float1282mpn.c: New file.
	* sysdeps/ieee754/float128/float128_private.h: Include gmp.h before
	redefining __mpn_extract_long_double to __mpn_extract_float128, then
	redefine __mpn_extract_long_double to __mpn_extract_float128.
	* sysdeps/ieee754/ldbl-128/ldbl2mpn.c: Replace long double with
	_Float128 to allow float128_private.h overrides.

Include sys/param.h in stdlib/gmp-impl.h instead of redefining MAX/MIN

2017-06-01T23:44:22+00:00

In stdlib/gmp-impl.h, the macros MAX and MIN are defined exactly the same
as in sys/param.h.  This patch removes the redefinition and makes
gmp-impl.h include sys/param.h instead.

Tested for powerpc64le and s390x.

	* stdlib/gmp-impl.h: Include sys/param.h instead of redefining the
	macros MAX and MIN.

Remove various ABS macros and replace uses with fabs (or in one case abs)

2015-05-15T11:04:40+00:00

which is more efficient on all targets.

stdlib/gmp-impl.h: Silence -Wundef warning for USE_STACK_ALLOC

2014-05-14T13:11:48+00:00

The upstream version of GMP has long removed this conditional
altogether in this commit:

changeset:   5254:88618a4694ac
user:        Kevin Ryde 
date:        Sun Jun 17 01:37:27 2001 +0200

So just turn the #if into an #ifdef to silence the warning.

ChangeLog:

2014-05-14  Will Newton  

	* stdlib/gmp-impl.h: Test USE_STACK_ALLOC #ifdef
	rather than #if.
