The new tests seems ok, but on my environment (gcc version 14.1.1, AMD Ryzen 9 5900X)
I see some additional ulps:
FAIL: math/test-float64x-log2p1
FAIL: math/test-ldouble-log2p1
$ cat math/test-ldouble-log2p1.out
testing long double (without inline functions)
Failure: Test: log2p1 (0x5.dda3a1f4c4020ebp-4)
Result:
is: 4.50602782011001241062e-01 0xe.6b56868729ec0e10p-5
should be: 4.50602782011001240953e-01 0xe.6b56868729ec0dd0p-5
difference: 1.08420217248550443401e-19 0x8.0000000000000000p-66
ulp : 4.0000
max.ulp : 3.0000
Maximal error of `log2p1'
is : 4 ulp
accepted: 3 ulp
Test suite completed:
4 max error test cases,
548 input tests,
- with 2200 tests for exception flags,
- with 524 tests for errno executed.
2 errors occurred.
So maybe update the patch to avoid additional changes.
