Code:

head:
    .set RACE, XXXX #replace XXXX with the lower 16 bits of your address
    lis r12, 0x80E4
    
    lbz r11, 0x74A4(r12) #load value into r11
    
    lis r12, 0xYYYY #replace YYYY with the upper 16 bits of your address
    cmpwi r11, 1
    bne not #if value != 1, we are not in a race, branch to not
    b in #else branch to in

not:
    li r10, 0
    b end

in:
    li r10, 1

end:
    stb r10, RACE(r12) #finally, store r10 at your desired location
