<!--LLVM PR SUMMARY COMMENT--> @llvm/pr-subscribers-clang Author: Alex Voicu (AlexVlx) <details> <summary>Changes</summary> Currently neither the SPIR nor the SPIRV targets specify the AS for globals in their datalayout strings. This is problematic because CodeGen/LLVM will default to AS0 in this case, which produces Globals that end up in the private address space for e.g. OCL, HIPSPV or SYCL. This patch addresses it by completing the datalayout string. --- Full diff: https://github.com/llvm/llvm-project/pull/88455.diff 2 Files Affected: - (modified) clang/lib/Basic/Targets/SPIR.h (+4-4) - (modified) clang/test/CodeGen/target-data.c (+2-2) ``````````diff diff --git a/clang/lib/Basic/Targets/SPIR.h b/clang/lib/Basic/Targets/SPIR.h index e25991e3dfe821..9a4a8b501460b6 100644 --- a/clang/lib/Basic/Targets/SPIR.h +++ b/clang/lib/Basic/Targets/SPIR.h @@ -259,7 +259,7 @@ class LLVM_LIBRARY_VISIBILITY SPIR32TargetInfo : public SPIRTargetInfo { SizeType = TargetInfo::UnsignedInt; PtrDiffType = IntPtrType = TargetInfo::SignedInt; resetDataLayout("e-p:32:32-i64:64-v16:16-v24:32-v32:32-v48:64-" - "v96:128-v192:256-v256:256-v512:512-v1024:1024"); + "v96:128-v192:256-v256:256-v512:512-v1024:1024-G1"); } void getTargetDefines(const LangOptions &Opts, @@ -276,7 +276,7 @@ class LLVM_LIBRARY_VISIBILITY SPIR64TargetInfo : public SPIRTargetInfo { SizeType = TargetInfo::UnsignedLong; PtrDiffType = IntPtrType = TargetInfo::SignedLong; resetDataLayout("e-i64:64-v16:16-v24:32-v32:32-v48:64-" - "v96:128-v192:256-v256:256-v512:512-v1024:1024"); + "v96:128-v192:256-v256:256-v512:512-v1024:1024-G1"); } void getTargetDefines(const LangOptions &Opts, @@ -336,7 +336,7 @@ class LLVM_LIBRARY_VISIBILITY SPIRV32TargetInfo : public BaseSPIRVTargetInfo { SizeType = TargetInfo::UnsignedInt; PtrDiffType = IntPtrType = TargetInfo::SignedInt; resetDataLayout("e-p:32:32-i64:64-v16:16-v24:32-v32:32-v48:64-" - "v96:128-v192:256-v256:256-v512:512-v1024:1024"); + "v96:128-v192:256-v256:256-v512:512-v1024:1024-G1"); } void getTargetDefines(const LangOptions &Opts, @@ -357,7 +357,7 @@ class LLVM_LIBRARY_VISIBILITY SPIRV64TargetInfo : public BaseSPIRVTargetInfo { SizeType = TargetInfo::UnsignedLong; PtrDiffType = IntPtrType = TargetInfo::SignedLong; resetDataLayout("e-i64:64-v16:16-v24:32-v32:32-v48:64-" - "v96:128-v192:256-v256:256-v512:512-v1024:1024"); + "v96:128-v192:256-v256:256-v512:512-v1024:1024-G1"); } void getTargetDefines(const LangOptions &Opts, diff --git a/clang/test/CodeGen/target-data.c b/clang/test/CodeGen/target-data.c index acff367d50eb91..c184f314f68f80 100644 --- a/clang/test/CodeGen/target-data.c +++ b/clang/test/CodeGen/target-data.c @@ -251,11 +251,11 @@ // RUN: %clang_cc1 -triple spir-unknown -o - -emit-llvm %s | \ // RUN: FileCheck %s -check-prefix=SPIR -// SPIR: target datalayout = "e-p:32:32-i64:64-v16:16-v24:32-v32:32-v48:64-v96:128-v192:256-v256:256-v512:512-v1024:1024" +// SPIR: target datalayout = "e-p:32:32-i64:64-v16:16-v24:32-v32:32-v48:64-v96:128-v192:256-v256:256-v512:512-v1024:1024-G1" // RUN: %clang_cc1 -triple spir64-unknown -o - -emit-llvm %s | \ // RUN: FileCheck %s -check-prefix=SPIR64 -// SPIR64: target datalayout = "e-i64:64-v16:16-v24:32-v32:32-v48:64-v96:128-v192:256-v256:256-v512:512-v1024:1024" +// SPIR64: target datalayout = "e-i64:64-v16:16-v24:32-v32:32-v48:64-v96:128-v192:256-v256:256-v512:512-v1024:1024-G1" // RUN: %clang_cc1 -triple bpfel -o - -emit-llvm %s | \ // RUN: FileCheck %s -check-prefix=BPFEL `````````` </details> https://github.com/llvm/llvm-project/pull/88455 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
