All these failures are gone when glibc is compiled with -O2 instead of -O3 but there are still 4 regressions : math/test-ildoubl Usual math problem : testing long double (inline functions) 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 libio/tst-fopenloc2 libio/tst-fopenloc These two seems to be a new gcc regression, they crash when compiled with gcc trunk. elf/check-localplt These seems to be less harmful, shows memalign is missing from expected output. Any ideas appreciated. Regards, ismail -- Never learn by your mistakes, if you do you may never dare to try again.
