Hello,
I ran into compiler warnings with the perfmon code when I tried
using test() and __set_bit() on i386.
For some reason, the i386 bitops functions use unsigned long * for
the address whereas x86-64/ia64 use void *.
I do not quite understand why such difference?
Is this just for historical reasons?
Thanks.
Arguably void * is the right thing for a littleendian architecture. For
bigendian architectures it unfortunately matters what the chunk size is,
regardless of if the chunks are numbered in bigendian (reverse) or
littleendian (forward) order.
