Although the lines for fma went away with enabling -mieee, there are new fma_towardzero lines: # fma_towardzero Test "fma_towardzero (-0x1.ffffffffffffcp-1022, 0x1.0000000000001p-1, -0x1p-1074)": double: 1 idouble: 1 Test "fma_towardzero (-0x1p-1074, 0x1.1p-1, -0x0.fffffffffffffp-1022)": double: 1 idouble: 1 Test "fma_towardzero (0x1.ffffffffffffcp-1022, 0x1.0000000000001p-1, 0x1p-1074)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, -0x1p-1074, 0x0.fffffffffffffp-1022)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, -0x1p-1074, 0x1p-1022)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, -0x1p-1074, 0x1p-1074)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, -0x1p-1074, 0x1p1023)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, 0x1.1p-1, 0x0.fffffffffffffp-1022)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, 0x1p-1074, -0x0.fffffffffffffp-1022)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, 0x1p-1074, -0x1p-1022)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, 0x1p-1074, -0x1p-1074)": double: 1 idouble: 1 Test "fma_towardzero (0x1p-1074, 0x1p-1074, -0x1p1023)": double: 1 idouble: 1 -- You are receiving this mail because: You are on the CC list for the bug.
