[LLVMdev] i80 data type
Dear all,
Is there anyone who knows well i80 data type? Is there any
corresponding data type
for X86 processor? uint80_t or int80_t for gcc?
PS. I found that the LLVM website is down!

no, there is no native processor support for i80. GCC does not have
a direct equivalent to i80. However if you declare a 80-bit wide C
bitfield, then arithmetic on it is done in 80 bits. For example,
here gcc should perform i3 arithmetic:
#include <stdio.h>
struct i3...
