[Qemu-devel] [PATCH 083/111] m68k: flush flags before negx instruction.

[Bryce Lanham]

From: Laurent Vivier <address@hidden>

Force the computing of the flags before negx as
negx will keep Z flag from previous instructions
if result is non zero.

Seen with gcc testsuite,
gcc.c-torture/execute/builtin-bitops-1.c
