Joseph Myers 8d0bf2d6e1 softfloat: return low bits of quotient from floatx80_modrem ... Both x87 and m68k need the low parts of the quotient for their remainder operations. Arrange for floatx80_modrem to track those bits and return them via a pointer. The architectures using float32_rem and float64_rem do not appear to need this information, so the *_rem interface is left unchanged and the information returned only from floatx80_modrem. The logic used to determine the low 7 bits of the quotient for m68k (target/m68k/fpu_helper.c:make_quotient) appears completely bogus (it looks at the result of converting the remainder to integer, the quotient having been discarded by that point); this patch does not change that, but the m68k maintainers may wish to do so. Backports commit 445810ec915687d37b8ae0ef8d7340ab4a153efa from qemu		2021-02-25 13:39:10 -05:00
