i have defined a var. as uint64_t var;
in asm construct finally the value from mm1(mmx
register) is copied to this var
"movq %%mm1,%0\n"
the operand used is like this
:"=g"(var)
actually what i want to ask is it(movq) is not able to
transfer the value to this var. it is working as movd
and is working for 32 bit integers.
what is this 'g' operand. as i know its for system to
decide how it treats it
thanks
ankit jain
