Labeling in MIPS with branches statements

Question

Does a label still execute if it is not specifically called?

Assuming I have

beq $t0, $t1, LABEL1
LABEL1: add $t0,$t2,$t1
beq $t0, $t3, LABEL2
LABEL2: add $t0, $t3, $t4

When I run this, will LABEL2 happen even if $t0 and $t3 are not equal?

Answer 1

When I run this, [will] LABEL2 happen even if $t0 and $t3 are not equal?

Yes.
Although a label doesn't really execute: a label is just a name that you've given to a specific location in your program, which helps you refer to that location in a simple manner. It's the instructions that are executed.
