+SPARC32-bit SDIV of negative divisor gives wrong result
+Description of problem:
+SDIV of negative divisor gives wrong result because of typo in helper_sdiv(). This is true for QEMU 9.0.0 and earlier.
+
+Place -1 in the Y register and -128 in another reg, then -120 in another register and do SDIV into a result register, instead of the proper value of 1 for the result, the incorrect value of 0 is produced.
+
+There is a typo in target/sparc/helper.c that causes the divisor to be consider unsigned, this patch fixes it:
