1fff1166 - [OpenMP] Change OpenMP code generation for target region entries

Fri, 24 Jun 2022 13:13:53 +0000

[OpenMP] Change OpenMP code generation for target region entriesThis patch changes the code we generate to enter a target region on thedevice. This is in-line with the new definition in the runtime that wasadded previously. Additionally we implement this in the OpenMPIRBuilderso that this code can be shared with Flang in the future.Reviewed By: ABataevDifferential Revision: https://reviews.llvm.org/D128550 List of files: /llvm-project-15.0.7/clang/test/OpenMP/nvptx_target_requires_unified_shared_memory.cpp

532dc62b - [OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC)

Thu, 07 Apr 2022 10:03:55 +0000

[OpaquePtrs][Clang] Add -no-opaque-pointers to tests (NFC)This adds -no-opaque-pointers to clang tests whose output willchange when opaque pointers are enabled by default. 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/OpenMP/nvptx_target_requires_unified_shared_memory.cpp

fd739804 - [test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences

Thu, 31 Dec 2020 08:27:11 +0000

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differencesFor a default visibility external linkage definition, dso_local is set for ELF-fno-pic/-fpie and COFF and Mach-O. 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 `{{.*}} `.

These symbols indicate the start address and end address of the output section respectively. Therefore, renaming OpenMP offload entries section name from ".omp.offloading_entries" to "omp_offloading_entries" to use this feature.This is the first part of the patch for eliminating OpenMP linker script (please see https://reviews.llvm.org/D64943).Differential Revision: https://reviews.llvm.org/D68070llvm-svn: 373118 List of files: /llvm-project-15.0.7/clang/test/OpenMP/nvptx_target_requires_unified_shared_memory.cpp
