Author: tomtan Date: Wed Feb 6 12:08:26 2019 New Revision: 353337 URL: http://llvm.org/viewvc/llvm-project?rev=353337&view=rev Log: [COFF, ARM64] Add ARM64 support for MS intrinsic _fastfail
The MSDN document was also updated to reflect this, but it probably will take a few days to show in below link. https://docs.microsoft.com/en-us/cpp/intrinsics/fastfail Differential Revision: https://reviews.llvm.org/D57631 Modified: cfe/trunk/lib/CodeGen/CGBuiltin.cpp cfe/trunk/test/CodeGen/ms-intrinsics.c Modified: cfe/trunk/lib/CodeGen/CGBuiltin.cpp URL: http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/CodeGen/CGBuiltin.cpp?rev=353337&r1=353336&r2=353337&view=diff ============================================================================== --- cfe/trunk/lib/CodeGen/CGBuiltin.cpp (original) +++ cfe/trunk/lib/CodeGen/CGBuiltin.cpp Wed Feb 6 12:08:26 2019 @@ -997,6 +997,9 @@ Value *CodeGenFunction::EmitMSVCBuiltinE Asm = "udf #251"; Constraints = "{r0}"; break; + case llvm::Triple::aarch64: + Asm = "brk #0xF003"; + Constraints = "{w0}"; } llvm::FunctionType *FTy = llvm::FunctionType::get(VoidTy, {Int32Ty}, false); llvm::InlineAsm *IA = Modified: cfe/trunk/test/CodeGen/ms-intrinsics.c URL: http://llvm.org/viewvc/llvm-project/cfe/trunk/test/CodeGen/ms-intrinsics.c?rev=353337&r1=353336&r2=353337&view=diff ============================================================================== --- cfe/trunk/test/CodeGen/ms-intrinsics.c (original) +++ cfe/trunk/test/CodeGen/ms-intrinsics.c Wed Feb 6 12:08:26 2019 @@ -9,7 +9,7 @@ // RUN: | FileCheck %s --check-prefixes CHECK,CHECK-X64,CHECK-ARM-X64,CHECK-INTEL // RUN: %clang_cc1 -ffreestanding -fms-extensions -fms-compatibility -fms-compatibility-version=17.00 \ // RUN: -triple aarch64-windows -Oz -emit-llvm %s -o - \ -// RUN: | FileCheck %s --check-prefixes CHECK-ARM-ARM64,CHECK-ARM-X64 +// RUN: | FileCheck %s --check-prefixes CHECK-ARM-ARM64,CHECK-ARM-X64,CHECK-ARM64 // intrin.h needs size_t, but -ffreestanding prevents us from getting it from // stddef.h.
