-Subject: expm1 ulps
-
-If you test glibc on i686 with GCC 4.3, you get a test-ildoubl failure:
-
-Failure: Test: expm1 (1) == M_El - 1.0
-Result:
- is: 1.71828182845904523532e+00 0xd.bf0a8b14576953500000p-3
- should be: 1.71828182845904523543e+00 0xd.bf0a8b14576953600000p-3
- difference: 1.08420217248550443401e-19 0x8.00000000000000000000p-66
- ulp : 1.0000
- max.ulp : 0.0000
-Maximal error of `expm1'
- is : 1 ulp
- accepted: 0 ulp
-
-What happens is that the inline expansion of expm1l uses __builtin_expm1l,
-and GCC 4.3 optimizes calls to __builtin_expm1l with constant argument to
-a correctly rounded result using MPFR. The result returned is thus the
-value of e-1 rounded once to long double precision. However, the test
-expects M_El - 1.0, and the result of rounding e to long double precision,
-then subtracting 1, differs in the last place from the result of rounding
-e-1 to long double precision (the latter has smaller exponent, and the
-last bit is 1).
-
-There are two obvious approaches possible to fixing this. The first patch
-below changes the expectation to a decimal expansion for e-1 (taken from
-that of M_El) rather than doing arithmetic in the expected value. This in
-turn requires ulps to be set for the out-of-line version of expm1. It
-might also need ulps to be set for the inline version for older compilers
-if they should continue to pass the test, and possibly for other targets.
-The second patch below takes the alternative approach of keeping the
-existing expectation (which has the wrong bit in the last place) and
-setting ulps for the inline expansion of expm1, which avoids the risk of
-breaking the test for other targets.
