In C assembly, the following code gives me the error when compiling,

output.s:5: Error: operand type mismatch for 'push'

output.s:6: Error: operand type mismatch for 'push'

.globl compute

compute:
pushq $9223372036854775807
pushq $9223372036854775807
popq  %r10
popq  %r11
imulq %r10, %r11
pushq %r11
popq  %rax
retq

And I think it's because the constants that are pushed are too large.

Well, use a calculator to find out what the largest quadword is in decimal – Martin James Apr 09 '16 at 19:37
@MartinJames and that's 9223372036854775807, if signed. Different problem. – harold Apr 09 '16 at 20:51
