History
Wilco Dijkstra 1294b1892e Add support for sqrt asm redirects 
This patch series cleans up the many uses of  __ieee754_sqrt(f/l) in GLIBC.
The goal is to enable GCC to do the inlining, and if this fails call the
__ieee754_sqrt function.  This is done by internally declaring sqrt with asm
redirects.  The compat symbols and sqrt wrappers need to disable the redirect.
The redirect is also disabled if there are already redirects defined when
using -ffinite-math-only.

All math functions (but not math tests, non-library code and libnldbl) are
built with -fno-math-errno which means GCC will typically inline sqrt as a
single instruction.  This means targets are no longer forced to add a special
inline for sqrt.

	* include/math.h (sqrt): Declare with asm redirect.
	(sqrtf): Likewise.
	(sqrtl): Likewise.
	(sqrtf128): Likewise.
	* Makeconfig: Add -fno-math-errno for libc/libm, but build testsuite,
	nonlib and libnldbl with -fmath-errno.
	* math/w_sqrt_compat.c: Define NO_MATH_REDIRECT.
	* math/w_sqrt_template.c: Likewise.
	* math/w_sqrtf_compat.c: Likewise.
	* math/w_sqrtl_compat.c: Likewise.
	* sysdeps/i386/fpu/w_sqrt.c: Likewise.
	* sysdeps/i386/fpu/w_sqrt_compat.c: Likewise.
	* sysdeps/generic/math-type-macros-float128.h: Remove math.h and
	complex.h.
