[Gcl-devel] Re: BFD relocations

[Camm Maguire]

Greetings!  I found an earlier cache flushing snippet for another
arch:

#define CLEAR_CACHE do { unsigned long ps = getpagesize(); \
			 char *beg = (char *)((unsigned long )(memory->cfd.cfd_start) & ~(ps-1)); \
			 char *end =  ROUND_UP(memory->cfd.cfd_start + \
				          memory->cfd.cfd_size,ps); \
			   mprotect(beg,end-beg,PROT_READ|PROT_WRITE|PROT_EXEC);} while(0)

Can mprotect be used in this way to portably flush the data cache?

Thanks!
