H.J. Lu c5c666f349 s_sincosf.h: Change pio4 type to float [BZ #28713]
s_cosf.c and s_sinf.c have

  if (abstop12 (y) < abstop12 (pio4))

where abstop12 takes a float argument, but pio4 is static const double.
pio4 is used only in calls to abstop12 and never in arithmetic.  Apply

-static const double pio4 = 0x1.921FB54442D18p-1;
+static const float pio4 = 0x1.921FB6p-1f;

to fix:

FAIL: math/test-float-cos
FAIL: math/test-float-sin
FAIL: math/test-float-sincos
FAIL: math/test-float32-cos
FAIL: math/test-float32-sin
FAIL: math/test-float32-sincos

when compiling with GCC 12.
