Hello,
while looking for some assembly out of order / optimization stuff
for something else, I found some strange code in
.../linux/include/asm-cris/bitops.h:22
/*
* Some hacks to defeat gcc over-optimizations..
*/
struct __dummy { unsigned long a[100]; };
#define ADDR (*(struct __dummy *) addr)
#define CONST_ADDR (*(const struct __dummy *) addr)
CONST_ADDR is never used in the kernel.
Maybe some -cris people could have a look.
Thanks,
