The issue involves the fldl instruction in i386 emulation, which affects how floating-point operations are handled. From what I remember, fldl loads a double-precision float into the FPU stack. + +The problem seems to be with the precision control bits of the FPU control word, specifically in QEMU's softfloat implementation after a certain commit. The output is incorrect when converting from float64 to floatx80.
