This patch fixes the __copysignf optimized macro meant to internal libm usage when used with constant value. Without the explicit cast to float, if it is used with const double value (for instance, on s_casinhf.c) double constants will be used and it may lead to precision issues in some algorithms. It fixes the following failures on PPC64/POWER7: Failure: Test: Real part of: cacos_downward (inf + 0 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 Failure: Test: Real part of: cacos_downward (inf - 0 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 Failure: Test: Real part of: cacos_downward (inf + 0.5 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 Failure: Test: Real part of: cacos_downward (inf - 0.5 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 Failure: Test: Real part of: cacos_towardzero (inf + 0 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 Failure: Test: Real part of: cacos_towardzero (inf - 0 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 Failure: Test: Real part of: cacos_towardzero (inf + 0.5 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 Failure: Test: Real part of: cacos_towardzero (inf - 0.5 i) Result: is: 1.19209289550781250000e-07 0x1.00000000000000000000p-23 should be: 0.00000000000000000000e+00 0x0.00000000000000000000p+0 |
