In this case I've dropped the use-new-pm option entirely,as I don't think this is considered part of the public interface.This also makes -debug-pass-manager work with llvm-lto, becausethat was needed to migrate some tests to NewPM.Differential Revision: https://reviews.llvm.org/D123376 List of files: /llvm-project-15.0.7/llvm/test/ThinLTO/X86/devirt_external_comdat_same_guid.ll Fri, 08 Apr 2022 08:54:20 +0000 Nikita Popov <npopov@redhat.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/ThinLTO/X86/devirt_external_comdat_same_guid.ll#2f63d549 Restore "[LTO/WPD] Enable aggressive WPD under LTO option"This restores 59733525d37cf9ad88b5021b33ecdbaf2e18911c (D71913), alongwith bot fix 19c76989bb505c3117730c47df85fd3800ea2767.The bot failure should be fixed by D73418, committed asaf954e441a5170a75687699d91d85e0692929d43.I also added a fix for non-x86 bot failures by requiring x86 in new testlld/test/ELF/lto/devirt_vcall_vis_public.ll.

It then changes WPD to skipdevirtualization for a virtual function call when any of the compatiblevtables has public vcall visibility.Additionally, internal LLVM options as well as lld and gold-pluginoptions are added which enable upgrading all public vcall visibilityto linkage unit (hidden) visibility during LTO. This enables the moreaggressive WPD to kick in based on LTO time knowledge of the visibilityguarantees.Support was added to all flavors of LTO WPD (regular, hybrid andindex-only), and to both the new and old LTO APIs.Unfortunately it was not simple to split the first and second parts ofthis part of the change (the unconditional emission of type tests andthe upgrading of the vcall visiblity) as I needed a way to upgrade thepublic visibility on legacy WPD llvm assembly tests that don't includelinkage unit vcall visibility specifiers, to avoid a lot of test churn.I also added a mechanism to LowerTypeTests that allows dropping typetest assume sequences we now aggressively insert when we invokedistributed ThinLTO backends with null indexes, which is used in testingmode, and which doesn't invoke the normal ThinLTO backend pipeline.Depends on D71907 and D71911.Reviewers: pcc, evgeny777, steven_wu, espindolaSubscribers: emaste, Prazek, inglorion, arichardson, hiraditya, MaskRay, dexonsmith, dang, davidxl, cfe-commits, llvm-commitsTags: #clang, #llvmDifferential Revision: https://reviews.llvm.org/D71913 List of files: /llvm-project-15.0.7/llvm/test/ThinLTO/X86/devirt_external_comdat_same_guid.ll Thu, 26 Dec 2019 19:40:18 +0000 Teresa Johnson <tejohnson@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/ThinLTO/X86/devirt_external_comdat_same_guid.ll#2cefb939 [ThinLTO/WPD] Remove an overly-aggressive assertSummary:An assert added to the index-based WPD was trying to verify that we onlyhave multiple vtables for a given guid when they are all non-externallinkage. This is too conservative because we may have multiple externalvtable with the same guid when they are in comdat. Remove the assert,as we don't have comdat information in the index, the linker shouldissue an error in this case.See discussion on D71040 for more information.Reviewers: evgeny777, aganeaSubscribers: mehdi_amini, inglorion, hiraditya, steven_wu, dexonsmith, llvm-commitsTags: #llvmDifferential Revision: https://reviews.llvm.org/D72648 List of files: /llvm-project-15.0.7/llvm/test/ThinLTO/X86/devirt_external_comdat_same_guid.ll Mon, 13 Jan 2020 21:50:41 +0000 Teresa Johnson <tejohnson@google.com>
