implements the single C increment instruction (x=x+1).(x=x+1).

5.6. Consider the following program: P1: { P2: 1 shared int x; shared int x; x = 10; x = 10; while (1) while (1) { x = x - 1; x = x - 1; x = x + 1; x = x + 1; if (x != 10) if (x!=10) printf("x is $d",x) printf ("x is %d", x) } } } } } } Note the scheduler in a uniprocessor system would implement pseudo-parallel execution of these two concurrent processes interleaving their instructions, without restriction on the order of the interleaving. a. Show a sequence (i.e., trace the sequence of interleavings of statements) such that the statement "x is 10 is printed. b. Show a sequence such that the statement "x is 8 is printed. You should remember that the increment/decrements at the source language level are not done atomically, that is, the assembly language code: LD RO, X /* load R0 from memory location x */ INCR RO / increment RO */ STO RO, X / store the incremented value back in x */
