how to clear the D_cache and I_cache in the MIPS linux ?
I am porting native‐code compilation to a JavaScript engine in the MIPS
platform.After the program
finished dynamic and transparent binary translation，it first write back the code into the memory from
D_CACHE,then invalidate I_CACHE,then run the code. My MIPS does not have SYNCI instruction,Cache
instruction is a privilege instruction, the program has no right to use it. So , What can I do ?
Very grateful for any reply !!!

use cacheflush()

use
cacheflush()
It is preferable to always use cacheflush(). The plan is to eventually enhance the cacheflush(3) library function to use SYNCI as applicable for a particular platform.
