This email made me go back and double check. I still see this on i686: FAIL: math/test-double-erfc FAIL: math/test-double-tgamma FAIL: math/test-float32x-erfc FAIL: math/test-float32x-tgamma FAIL: math/test-float64-erfc FAIL: math/test-float64-tgamma These are all ULPs failures we need to fix for the release. I see this on armv7hl: FAIL: math/test-double-asinh FAIL: math/test-double-cbrt FAIL: math/test-double-cosh FAIL: math/test-double-erfc FAIL: math/test-double-exp FAIL: math/test-double-sinh FAIL: math/test-double-tgamma FAIL: math/test-float32x-asinh FAIL: math/test-float32x-cbrt FAIL: math/test-float32x-cosh FAIL: math/test-float32x-erfc FAIL: math/test-float32x-exp FAIL: math/test-float32x-sinh FAIL: math/test-float32x-tgamma FAIL: math/test-float64-asinh FAIL: math/test-float64-cbrt FAIL: math/test-float64-cosh FAIL: math/test-float64-erfc FAIL: math/test-float64-exp FAIL: math/test-float64-sinh FAIL: math/test-float64-tgamma FAIL: math/test-ldouble-asinh FAIL: math/test-ldouble-cbrt FAIL: math/test-ldouble-cosh FAIL: math/test-ldouble-erfc FAIL: math/test-ldouble-exp FAIL: math/test-ldouble-sinh FAIL: math/test-ldouble-tgamma These are all ULPs failures also and we need to fix them for the release. This will all be done when we reset the ULPs. -- Cheers, Carlos.
