8d291eabd5 Apply asm redirection in gmp.h before first use 
For clang the redeclaration after the first use, the visibility attribute
is silently ignored (symbol is STV_DEFAULT) while the asm label attribute
causes an error.

a2ca165230 Mark internal gmp functions with attribute_hidden [BZ #18822] 
Mark internal gmp functions with attribute_hidden to allow direct
access within libc.so and libc.a without using GOT nor PLT.

	undefined.

45f39d4588 float128: Add strtof128, wcstof128, and related functions. 
The implementations are contained with sysdeps/ieee754/float128 as
they are only built when _Float128 is enabled within libc/m.

	* include/gmp.h (__mpn_construct_float128): New declaration.
	* include/stdlib.h: Include bits/floatn.h for _Float128 tests.
	(__strtof128_l): New declaration.

	(__wcstof128_internal): Likewise.

	* stdlib/Makefile (bug-strtod2): Link libm too.

	* stdlib/stdlib.h (strtof128): New declaration.
	(strtof128_l): Likewise.

	* stdlib/tst-strtod-nan-locale-main.c: Updated to use
	tst-strtod.h macros to ensure float128 gets tested too.

	* stdlib/tst-strtod-round-skeleton.c (CHOOSE_f128): New macro.

	* stdlib/tst-strtod.h: Include bits/floatn.h for _Float128
	tests.
	(IF_FLOAT128): New macro.
	(GEN_TEST_STRTOD): Update to optionally include _Float128 in
	the tests.
	(STRTOD_TEST_FOREACH): Likewise.

	* sysdeps/ieee754/float128/Makefile: Insert new strtof128 and
	wcstof128 functions into libc.

	* sysdeps/ieee754/float128/Versions: Add exports for the above
	new functions.

32bf1d09da float128: Add conversion from float128 to mpn 
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.
