Chapter 5.12, Problem 5.11PP
Program Plan Intro
Given Assembly code:
a in %rdi, i in %rax, cnt in %rdx
.L5:
vmovss -4(%rsi, %rax, 4), %xmm0
vaddss (%rdi, %rax, 4), %xmm0, %xmm0
vmovss %xmm0, (%rsi, %rax, 4)
addq $1, %rax
cmpq %rdx, %rax
jne .L5
Cycles per element (CPE):
- The CPE denotes performance of
program that helps in improving code. - It helps to understand detailed level loop performance for an iterative program.
- It is appropriate for programs that use a repetitive computation.
- The processor’s activity sequencing is controlled by a clock that provides regular signal of some frequency.
Memory aliasing:
- It denotes a case where two pointers might designate to memory location that is same.
- The compiler should assume that unlike pointers might be aliased for safe optimizations.
- The program aspects that could limit chances for a compiler in generating optimized code denote optimization blockers.
- If a compiler is unable to determine whether two pointers might be aliased, it should adopt that either case would be possible.
- The possible optimization set is been limited in this case.
