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.
