URL: https://github.com/llvm/llvm-project/commit/2921a0928c71f4ee652a2478283e47ab5ffebf58 DIFF: https://github.com/llvm/llvm-project/commit/2921a0928c71f4ee652a2478283e47ab5ffebf58.diff LOG: Make the argument -Xcuda-ptxas visible to the driver in cl-mode It has been noticed that the arguments are being passed twice to ptxas. This also has been fixed by filtering out the arguments before appending them to the new DAL created by CudaToolChain::TranslateArgs. github:https://github.com/llvm/llvm-project/pull/86807 Added: Modified: clang/include/clang/Driver/Options.td clang/lib/Driver/ToolChains/Cuda.cpp clang/test/Driver/cuda-external-tools.cu Removed: ################################################################################ diff --git a/clang/include/clang/Driver/Options.td b/clang/include/clang/Driver/Options.td index 827d9d7c0c18e4..f745e573eb2686 100644 --- a/clang/include/clang/Driver/Options.td +++ b/clang/include/clang/Driver/Options.td @@ -1003,7 +1003,8 @@ def : Joined<["-"], "Xclang=">, Group<CompileOnly_Group>, def Xcuda_fatbinary : Separate<["-"], "Xcuda-fatbinary">, HelpText<"Pass <arg> to fatbinary invocation">, MetaVarName<"<arg>">; def Xcuda_ptxas : Separate<["-"], "Xcuda-ptxas">, - HelpText<"Pass <arg> to the ptxas assembler">, MetaVarName<"<arg>">; + HelpText<"Pass <arg> to the ptxas assembler">, MetaVarName<"<arg>">, + Visibility<[ClangOption, CLOption]>; def Xopenmp_target : Separate<["-"], "Xopenmp-target">, Group<CompileOnly_Group>, HelpText<"Pass <arg> to the target offloading toolchain.">, MetaVarName<"<arg>">; def Xopenmp_target_EQ : JoinedAndSeparate<["-"], "Xopenmp-target=">, Group<CompileOnly_Group>, diff --git a/clang/lib/Driver/ToolChains/Cuda.cpp b/clang/lib/Driver/ToolChains/Cuda.cpp index 5f0b516e1a1a08..6634e6d818b33e 100644 --- a/clang/lib/Driver/ToolChains/Cuda.cpp +++ b/clang/lib/Driver/ToolChains/Cuda.cpp @@ -990,7 +990,10 @@ CudaToolChain::TranslateArgs(const llvm::opt::DerivedArgList &Args, } for (Arg *A : Args) { - DAL->append(A); + // Make sure flags are not duplicated. + if (!llvm::is_contained(*DAL, A)) { + DAL->append(A); + } } if (!BoundArch.empty()) { diff --git a/clang/test/Driver/cuda-external-tools.cu b/clang/test/Driver/cuda-external-tools.cu index 946e144fce38fb..d9564d026b4faa 100644 --- a/clang/test/Driver/cuda-external-tools.cu +++ b/clang/test/Driver/cuda-external-tools.cu @@ -86,6 +86,12 @@ // RUN: -Xcuda-fatbinary -bar1 -Xcuda-ptxas -foo2 -Xcuda-fatbinary -bar2 %s 2>&1 \ // RUN: | FileCheck -check-prefixes=CHECK,SM35,PTXAS-EXTRA,FATBINARY-EXTRA %s +// Check -Xcuda-ptxas with clang-cl +// RUN: %clang_cl -### -c -Xcuda-ptxas -foo1 \ +// RUN: --offload-arch=sm_35 --cuda-path=%S/Inputs/CUDA/usr/local/cuda \ +// RUN: -Xcuda-ptxas -foo2 %s 2>&1 \ +// RUN: | FileCheck -check-prefixes=CHECK,SM35,PTXAS-EXTRA %s + // MacOS spot-checks // RUN: %clang -### --target=x86_64-apple-macosx -O0 -c %s 2>&1 \ // RUN: --offload-arch=sm_35 --cuda-path=%S/Inputs/CUDA/usr/local/cuda \ @@ -140,6 +146,8 @@ // CHECK-SAME: "[[PTXFILE]]" // PTXAS-EXTRA-SAME: "-foo1" // PTXAS-EXTRA-SAME: "-foo2" +// CHECK-NOT: "-foo1" +// CHECK-NOT: "-foo2" // RDC-SAME: "-c" // CHECK-NOT: "-c" _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
