- Subject: Use M_SQRT1_2l instead of local M_SQRT_2_2 in libm-test.inc
One of the defined constants in libm-test.inc, M_SQRT_2_2, has exactly
the same semantics as M_SQRT1_2l in math.h. This patch changes the
test to use the macro in math.h directly instead. Tested x86_64 and
x86.
(Not strictly needed for moving libm-test.inc to be table-based, but
noticed in the course of preparation for that.)
2013-05-09 Joseph Myers <joseph@codesourcery.com>
* math/libm-test.inc (M_SQRT_2_2): Remove macro.
(csqrt_test): Use M_SQRT1_2l instead of M_SQRT_2_2.
