[BZ #13852]
* sysdeps/i386/fpu/e_rem_pio2f.c: Delete so that i386 uses the ieee754/flt-32 implementation. * sysdeps/i386/fpu/k_rem_pio2f.c: Likewise. * sysdeps/i386/fpu/s_cosf.S: Likewise. * sysdeps/i386/fpu/s_sincosf.S: Likewise. * sysdeps/i386/fpu/s_sinf.S: Likewise. * math/libm-test.inc (cos_test): Enable some large input tests for float as well (sin_test): Likewise. (sincos_test): Likewise. * sysdeps/i386/fpu/libm-test-ulps: Update.
