Nop, exactly the same error. Also, float_madds fails as: Files float_madds.out and tests/tcg/mips64el/float_madds.ref differ --- float_madds.out 2021-12-26 11:49:06.018532269 +0100 +++ tests/tcg/mips64el/float_madds.ref 2021-12-26 01:16:02.269497182 +0100 @@ -1,16 +1,16 @@ ### Rounding to nearest -op : f32(nan:0xffffffff) * f32(nan:0xffbfffff) + f32(-inf:0xff800000) -res: f32(nan:0x7fbfffff) flags=INVALID (0/0) -op : f32(nan:0xffbfffff) * f32(-inf:0xff800000) + f32(nan:0xffffffff) -res: f32(nan:0x7fbfffff) flags=INVALID (0/1) -op : f32(-inf:0xff800000) * f32(nan:0xffffffff) + f32(nan:0xffbfffff) -res: f32(nan:0x7fbfffff) flags=INVALID (0/2) make[2]: *** [tests/tcg/multiarch/Makefile.target:30: run-float_madds] Error 1
