Richard Henderson 583d121520 tcg-sparc: Implement division properly. ... The {div,divu}2 opcodes are intended for systems for which the division instruction produces both quotient and remainder. Sparc is not such a system. Indeed, the remainder must be computed as quot = a / b rem = a - (quot * b) Split out a tcg_out_div32 function that properly initializes Y with the extension of the input to 64-bits. Discard the code that used the 64-bit DIVX on sparc9/sparcv8plus without extending the inputs to 64-bits. Implement remainders in terms of division followed by multiplication.
