This drops the MemDep-based implementation.Differential Revision: https://reviews.llvm.org/D97877 List of files: /llvm-project-15.0.7/llvm/test/Transforms/DeadStoreElimination/X86/gather-null-pointer.ll Wed, 03 Mar 2021 19:38:50 +0000 Nikita Popov <nikita.ppv@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Transforms/DeadStoreElimination/X86/gather-null-pointer.ll#cee313d2 Revert "Temporarily Revert "Add basic loop fusion pass.""The reversion apparently deleted the test/Transforms directory.Will be re-reverting again.llvm-svn: 358552 List of files: /llvm-project-15.0.7/llvm/test/Transforms/DeadStoreElimination/X86/gather-null-pointer.ll Wed, 17 Apr 2019 04:52:47 +0000 Eric Christopher <echristo@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Transforms/DeadStoreElimination/X86/gather-null-pointer.ll#35f55d72 [X86] Remove IntrArgMemOnly from target specific gather/scatter intrinsicsIntrArgMemOnly implies that only memory pointed to by pointer typed arguments will be accessed. But these intrinsics allow you to pass null to the pointer argument and put the full address into the index argument. Other passes won't be able to understand this.A colleague found that ISPC was creating gathers like this and then dead store elimination removed some stores because it didn't understand what the gather was doing since the pointer argument was null.Differential Revision: https://reviews.llvm.org/D58805llvm-svn: 355228 List of files: /llvm-project-15.0.7/llvm/test/Transforms/DeadStoreElimination/X86/gather-null-pointer.ll Fri, 01 Mar 2019 21:02:40 +0000 Craig Topper <craig.topper@intel.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/Transforms/DeadStoreElimination/X86/gather-null-pointer.ll#e6bfb091 [X86] Add test case for D58805. NFCThis demonstrates dead store elimination removing a store that may alias a gather that uses null as its base.llvm-svn: 355227 List of files: /llvm-project-15.0.7/llvm/test/Transforms/DeadStoreElimination/X86/gather-null-pointer.ll Fri, 01 Mar 2019 21:02:34 +0000 Craig Topper <craig.topper@intel.com>
