assembly - What does `1<<0` do in this code snippet? -


what these lines of code ?

mbalign     equ  1<<0                    meminfo     equ  1<<1

i know equ declare constants in nasm, 1<<0 do?

it looks similar c bit operators far know in assembly use shl , etc.

although shift nothing makes things easier read, think of 

mbalign     equ  1<<0 meminfo     equ  1<<1

as saying

mbalign     equ  bit0 meminfo     equ  bit1 etc.
