Subject: 128-bit long long?
Date: Sun, 21 Mar 2004 17:34:00 -0000 [thread overview]
Message-ID: <405DB46B.80208@coyotegulch.com> (raw)
On a 64-bit AMD64 architecture, GCC defines long long as 64 bits, the
same as a long.
Given that certain 64-bit instructions (multiply) produce 128-bit
results, doesn't it seem logical the long long be defined as 128 bits?
I'm just wonder...
