EarlyCSE was added with D75145, but the motivating test is not regressed by removing the extra pass now. That might be because VectorCombine altered the way it processes instructions, or it might be from (re)moving VectorCombine in the pipeline. The extra round of EarlyCSE appears to cost approximately 0.26% in compile-time as discussed in D80236, so we need some evidence to justify its inclusion here, but we do not have that (yet). I suspect that between SLP and VectorCombine, we are creating patterns that InstCombine and/or codegen are not prepared for, but we will need to reduce those examples and include them as PhaseOrdering and/or test-suite benchmarks.

; The IR below was crafted so as:
|
|
; 1) To have a loop, so we create a loop pass manager
|
|
; 2) To be "immutable" in the sense that no pass in the standard
|
|
; pipeline will modify it.
|
|
; Since no transformations take place, we don't expect any analyses
|
|
; to be invalidated.
|
|
; Any invalidation that shows up here is a bug, unless we started modifying
|
|
; the IR, in which case we need to make it immutable harder.
