Laurent Vivier 68c9ab9b77 target/m68k: fix V flag for CC_OP_SUBx ... V flag for subtraction is: v = (res ^ src1) & (src1 ^ src2) (see COMPUTE_CCR() in target/m68k/helper.c) But gen_flush_flags() uses: v = (res ^ src2) & (src1 ^ src2) The problem has been found with the following program: .global _start _start: move.l #-2147483648,%d0 subq.l #1,%d0 jvc 1f move.l #1,%d1 move.l #1,%d0 trap #0 1: move.l #0,%d1 move.l #1,%d0 trap #0 It works fine (exit(1)) on real hardware, and with "-singlestep". "-singlestep" uses gen_helper_flush_flags(), whereas without "-singlestep", V flag is computed directly in gen_flush_flags(). This patch updates gen_flush_flags() to have the same result as with gen_helper_flush_flags(). Backports commit 043b936ef6fe53396b3c6b8f5562ea3e238a071d from qemu		2018-03-03 14:59:20 -05:00
