I cannot use li.s in MARS. I am new to MIPS programming and I am trying not to use any co processors. Why can I not use li.s is MARS the program? It would be very helpful is someone could lead me in a new direction!
You can achieve the same effect as the pseudoinstruction li.s using pseudoinstruction l.s and the constant stored in the data segment:
l.s $f1, fpconst
.data 0x1000
fpconst:
.float 1.2345
That will use the coprocessor register $f1 to store the floating point constant.
You can also put the constant in a regular register using lw $f1, fpconst instead of l.s
