[Qemu-devel] What TARGET_HAS_PRECISE_SMC means?

[陳韋任]

Hi all,

  I see only x86 define TARGET_HAS_PRECISE_SMC (target-i386/cpu.h), and the
comment says,

/* support for self modifying code even if the modified instruction is
   close to the modifying instruction */
#define TARGET_HAS_PRECISE_SMC

  I would like to know what it means and want to know more about it, but
googling doesn't help. Would you mind to shed some light on that? Thanks.

Regards,
chenwj
