The .align pseudo-instruction is valid for only the immediately following data definition pseudo-instruction.
.align <Boundary specifying value>
<Boundary specifying value>:
Sample description:
The data that appears immediately after this pseudo-instruction is aligned to a 2
boundary specification value)
Therefore, when defining data that requires alignment, you need to use the .align pseudo-instruction for
each data definition pseudo-instruction.
.global <Symbol>
<Symbol>: Symbol to be defined in the current file
Sample description:
Makes global declaration of a symbol. The declaration made in a file with a symbol defined converts that
symbol to a global symbol which can be referred to from other modules.
The symbols referenced from other modules must be declared to be global. The symbols defined by
the .comm pseudo-instruction are global symbols, so there is no need to use the .global pseudo-instruction
to make a declaration.
The symbols not declared in the current file are processed as global symbols that are declared in some other
file.
Value to specify a boundary
.align 2
.global SUB1
The values that can be specified are 0 to 8.
