| Thread-topic: | Question about alignment check in sh_x86_emulate_write |
In in sh_x86_emulate_write:
if ( vaddr & (bytes-1) )
return X86EMUL_UNHANDLE;
I met a problem the vaddr is not aligned on word or dword, but have to
emulate it.
I am wordering about the reason for this check. Is it safe to get rid of
it?
Best Regards,
Disheng, Su
