Jacques Pienaar	13bc82b587	[mlir] SCCP add missing pessimistic setting ... When this was updated in D127139 the update in-place case was no longer marked as pessimistic. Add back in. Differential Revision: https://reviews.llvm.org/D130453	2022-07-25 17:41:17 -07:00
Mogball	9432fbfe13	[mlir] An implementation of sparse data-flow analysis ... This patch introduces a (forward) sparse data-flow analysis implemented with the data-flow analysis framework. The analysis interacts with liveness information that can be provided by dead-code analysis to be conditional. This patch re-implements SCCP using dead-code analysis and (conditional) constant propagation analyses.

Mogball	c095afcba6	[mlir] Add Dead Code Analysis ... This patch implements the analysis state classes needed for sparse data-flow analysis and implements a dead-code analysis using those states to determine liveness of blocks, control-flow edges, region predecessors, and function callsites.
