with reference to the following:
struct data {
data (long v) : m_data (v) {}
data (const data&) {}
long m_data;
};
data foo (data v) {
return v;
}
my reading of the x86_64 ABI (v .98, sept 2006) on page 17 is that
data should have class MEMORY when passed as argument to
I'm tying to hunt down the cause of a bug I'm experiencing and it all
boils down to a possible misunderstanding
on my part on the semantics of the 'aligned' attribute.
Is the 'aligned' attribute supposed to work for objects allocated on
the stack (I'm on x86_64, gcc 4.1.1)?
The only caveat

I'm looking at the very same problem, hoping to get very lightweight
user-level threads for use in discrete event simulation.
It would be very nice if it was possible to write an inlined piece of
assembler that saved the program counter and the stack pointer and
then be able to say to GCC t
