ARM __clear_cache equivalent for iOS devices

I'm porting a library to the iPhone which makes a call to __clear_cache. A little research digs up this nice explanation of what it does.

The article lists the library functions for Linux, Windows and even Android. I don't suppose there is an equivalent for iOS devices? Or some other workaround I can implement?

Solution

  • As iOS is a *NIX-based platform, and you can compile code with apple's version of GCC (LLVM-GCC 4.2), you should just be able to make a function call to __clear_cache(), like this:

    extern void __clear_cache(char *beg, char *end);

__clear_cache(beg, end);

    Note that this will NOT work with Apple LLVM Compiler 3.1, only with GCC for some odd reason.
