MIPS Functions

MIPS Functions. Q uestions. A MIPS function is called by the jal instruction, which does two things: 1) going to the address of the first instruction in the function, 2) passing the arguments in $a0 to $a3. Q uestions. A MIPS function must be ended by the jr $ ra instruction. Questions.
