88003cea1c6eb3ebcb18b4f1b9d0e2052dd76fe4 - [MemCpyOpt] Remove MemDepAnalysis-based implementation

Sat, 08 May 2021 18:39:54 +0000

[MemCpyOpt] Remove MemDepAnalysis-based implementationThe MemorySSA-based implementation has been enabled for a few months(since D94376). This patch drops the old MDA-based implementationentirely.I've kept this to only the basic cleanup of dropping variousconditions -- the code could be further cleaned up now that thereis only one implementation.Differential Revision: https://reviews.llvm.org/D102113 List of files: /llvm-project/llvm/test/Transforms/MemCpyOpt/vscale-memset.ll

cd6f40f4326c8251ebb628122bf092ca5536a634 - [MemCpyOpt] Add test scaffolding for MSSA based MemCpyOpt

Fri, 02 Oct 2020 18:48:39 +0000

[MemCpyOpt] Add test scaffolding for MSSA based MemCpyOptThis adds an -enable-memcpyopt-memoryssa option that currently doesnothing apart from requiring MSSA as a dependency. The tests aresplit to run both with the option disabled and enabled. I went withthis rather than the separate directory DSE uses, as I found itconvenient to have a direct side-by-side comparison of differences.Differential Revision: https://reviews.llvm.org/D89206 List of files: /llvm-project/llvm/test/Transforms/MemCpyOpt/vscale-memset.ll
