Changes since v2:
- Do not declare pow10f128, gammaf128, and scalbf128.
-- 8< --
All the declarations in math-finite.h are macroized by floating-point
type. This patch includes it for float128 and protects the
declarations of functions that need not be declared for float128.
2017-05-09 Gabriel F. T. Gomes <gftg@linux.vnet.ibm.com>
* math/math.h: Include bits/math-finite.h for float128.
(__MATH_DECLARING_FLOAT128): Define to control declaration of
float128 functions.
* math/bits/math-finite.h (pow10): Do not declare for float128.
(gamma): Likewise.
(scalb): Likewise.
