Add more tests of exp, exp10, exp2, expm1.
This patch adds some randomly-generated tests of exp, exp10, exp2 and expm1 that are observed to increase ulps on x86_64. Tested for x86_64 and x86 and ulps updated accordingly. * math/auto-libm-test-in: Add more tests of exp, exp10, exp2 and expm1. * math/auto-libm-test-out: Regenerated. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
