Subject: bios_emulator: fix incorrect printing of address in "jump near immediate"
X-Git-Tag: v2025.04-rc1~17^2~46

bios_emulator: fix incorrect printing of address in "jump near immediate"

In the x86emuOp_jump_call_near_IMM() function the target address is
printed incorrectly when jumping backwards. For example instead of
"jmp 0xe8bc" the string "jmp ffffe8bc" is printed. That's because
of the following macro:

    DECODE_PRINTF2("%04x\n", ip);

while it should be

    DECODE_PRINTF2("%04x\n", (u16)ip);
