This isintended to be part of the migration approach described inhttps://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.The patch has been produced by replacing %clang_cc1 with%clang_cc1 -no-opaque-pointers for tests that fail with opaquepointers enabled. Worth noting that this doesn't cover all tests,there's a remaining ~40 tests not using %clang_cc1 that will needa followup change.Differential Revision: https://reviews.llvm.org/D123115 List of files: /llvm-project-15.0.7/clang/test/CodeGenCXX/RelativeVTablesABI/override-pure-virtual-method.cpp Thu, 07 Apr 2022 10:03:55 +0000 Nikita Popov <npopov@redhat.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CodeGenCXX/RelativeVTablesABI/override-pure-virtual-method.cpp#e6f88dc0 [clang][Fuchsia] Turn on relative-vtables by default for FuchsiaAll fuchsia targets will now use the relative-vtables ABI by default.Also remove -fexperimental-relative-c++-abi-vtables from test RUNs targeting fuchsia.Differential Revision: https://reviews.llvm.org/D102374 List of files: /llvm-project-15.0.7/clang/test/CodeGenCXX/RelativeVTablesABI/override-pure-virtual-method.cpp Wed, 12 May 2021 17:37:37 +0000 Leonard Chan <leonardchan@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CodeGenCXX/RelativeVTablesABI/override-pure-virtual-method.cpp#d1fd7234 Refactor how -fno-semantic-interposition sets dso_local on default visibility external linkage definitionsThe idea is that the CC1 default for ELF should set dso_local on defaultvisibility external linkage definitions in the default -mrelocation-model picmode (-fpic/-fPIC) to match COFF/Mach-O and make output IR similar.The refactoring is made available by 2820a2ca3a0e69c3f301845420e0067ffff2251b.Currently only x86 supports local aliases. We move the decision to the driver.There are three CC1 states:* -fsemantic-interposition: make some linkages interposable and make default visibility external linkage definitions dso_preemptable.* (default): selected if the target supports .Lfoo$local: make default visibility external linkage definitions dso_local* -fhalf-no-semantic-interposition: if neither option is set or the target does not support .Lfoo$local: like -fno-semantic-interposition but local aliases are not used. So references can be interposed if not optimized out.Add -fhalf-no-semantic-interposition to a few tests using the half-based semantic interposition behavior.

Since default clang -cc1 for ELF is similarto -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences.To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition,which sets dso_local for default visibility external linkage definitions.To make this flip smooth and enable future (dso_local as definition default),this patch replaces (function) `define ` with `define{{.*}} `,(variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

LLVM and LLD support theR_AARCH64_PLT32 relocation, so we can also guarantee a static PLT relocation on AArch64.Not emitting these stubs saves a lot of extra binary size.Differential Revision: https://reviews.llvm.org/D83812 List of files: /llvm-project-15.0.7/clang/test/CodeGenCXX/RelativeVTablesABI/override-pure-virtual-method.cpp Tue, 14 Jul 2020 21:56:38 +0000 Leonard Chan <leonardchan@google.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/CodeGenCXX/RelativeVTablesABI/override-pure-virtual-method.cpp#71568a9e [clang] Frontend components for the relative vtables ABI (round 2)This patch contains all of the clang changes from D72959.- Generalize the relative vtables ABI such that it can be used by other targets.- Add an enum VTableComponentLayout which controls whether components in the vtable should be pointers to other structs or relative offsets to those structs.
