The majority of existing tests are passing with a few exceptions(see below). The tests were running on QEMU, since currently there're no hardware with support for J-extension. For this feature to work the system must support PR_{SET,GET}_TAGGED_ADDR_CTRL syscall. For now this is only available for a patched Linux kernel and QEMU with enabled experimental J-extension. Results of running HWASAN lit tests for RISC-V: ``` Unsupported : 6 Passed : 79 Expectedly Failed: 2 ``` Tests are marked as expected to fail or unsupported either because of: - android platform not being supported - no support for legacy hwasan v1 mode - test config explicitly uses aarch64 option ``` UNSUPPORTED: HWAddressSanitizer-riscv64 :: TestCases/abort-message-android.cpp UNSUPPORTED: HWAddressSanitizer-riscv64 :: TestCases/cfi.cpp UNSUPPORTED: HWAddressSanitizer-riscv64 :: TestCases/lto.c UNSUPPORTED: HWAddressSanitizer-riscv64 :: TestCases/print-memory-usage-android.c UNSUPPORTED: HWAddressSanitizer-riscv64 :: TestCases/register-dump-read.c UNSUPPORTED: HWAddressSanitizer-riscv64 :: TestCases/try-catch.cpp XFAIL: HWAddressSanitizer-riscv64 :: TestCases/stack-oob.c XFAIL: HWAddressSanitizer-riscv64 :: TestCases/exported-tagged-global.c ``` Differential Revision: https://reviews.llvm.org/D131345 Added: Modified: clang/lib/Driver/ToolChains/Linux.cpp compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake Removed: ################################################################################ diff --git a/clang/lib/Driver/ToolChains/Linux.cpp b/clang/lib/Driver/ToolChains/Linux.cpp index ec35c1e98a3c0..ceb8b0f7daaf8 100644 --- a/clang/lib/Driver/ToolChains/Linux.cpp +++ b/clang/lib/Driver/ToolChains/Linux.cpp @@ -778,8 +778,10 @@ SanitizerMask Linux::getSupportedSanitizers() const { if (IsX86_64 || IsMIPS64 || IsAArch64 || IsX86 || IsMIPS || IsArmArch || IsPowerPC64 || IsHexagon || IsLoongArch64) Res |= SanitizerKind::Scudo; - if (IsX86_64 || IsAArch64) { + if (IsX86_64 || IsAArch64 || IsRISCV64) { Res |= SanitizerKind::HWAddress; + } + if (IsX86_64 || IsAArch64) { Res |= SanitizerKind::KernelHWAddress; } return Res; diff --git a/compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake b/compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake index 5c48a72f2a07d..069ce087e79d8 100644 --- a/compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake +++ b/compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake @@ -55,7 +55,7 @@ else() ${PPC64} ${S390X} ${RISCV64} ${HEXAGON}) endif() set(ALL_MSAN_SUPPORTED_ARCH ${X86_64} ${MIPS64} ${ARM64} ${PPC64} ${S390X}) -set(ALL_HWASAN_SUPPORTED_ARCH ${X86_64} ${ARM64}) +set(ALL_HWASAN_SUPPORTED_ARCH ${X86_64} ${ARM64} ${RISCV64}) set(ALL_MEMPROF_SUPPORTED_ARCH ${X86_64}) set(ALL_PROFILE_SUPPORTED_ARCH ${X86} ${X86_64} ${ARM32} ${ARM64} ${PPC32} ${PPC64} ${MIPS32} ${MIPS64} ${S390X} ${SPARC} ${SPARCV9} ${HEXAGON} _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
