我正在尝试学习 MIPS 汇编，因为我有一些空闲时间，并且我正在尝试编写一个将数字推入堆栈然后将它们弹出的程序。我希望它计算在达到负数之前弹出的数字的数量，然后每次它得到一个负数时，计算弹出了多少负数和正数。
到目前为止，我得到了这个：
#count the number of negative words on the stock by poping the stack until a non- negative word is found
#and print out the number of words found
.text
.globl main
#this code reads the numbers from the data area and stores in them in a stack
#the numbers are located in the test area and the number of numbers in the num area
main: la $t0, test
lw $t1, num
loop: lw $t2,($t0)
sub $sp, $sp, 4
sw $t2($sp)
add $t0, $t0, 4
add $t1, $t1, -1
bnez $t1, loop
#pop from the stack and print the number of numbers in the stack before a nonnegative number is reached
#then keep count of how many negative and positive ones there are total
#code I cannot come up with would go here
.data
test: .word
2, 0xfffabfff,2,-4,-9,0x99999999,0x90000000,-2147479536,0x80000000
num: .word 10
ans: .asciiz "Number is = "
endl: .asciiz "\n"
据我所知，我让它向右推动，但我无法弄清楚推动和计数的权利。我必须从这里做什么？
