From 8a0b400f3b20fb7e595af4b16b73f0fe998e8a86 Mon Sep 17 00:00:00 2001 From: Ivan Krasilnikov Date: Tue, 23 Dec 2025 18:28:19 +0800 Subject: [PATCH 1/7] Fix Linux ARM64 build Key issues during port: * Different ARM64 vararg calling convention between macOS (DarwinPCS) and Linux (AAPCS64). Fixed CALL_ENTRYPOINT_NOASSERT and DECLARE_ARGS_VARARRAY using va_list.__stack from the official ABI - robust and compiler-independent. However, there is also JavascriptStackWalker.cpp which depends on the exact stack layout and magic constants, especially ArgOffsetFromFramePtr, this part is more fragile. * char is unsigned in Linux ARM64 ABI unlike macOS/Win, breaking int8 code. Make sure __int8 (=char) is always prefixed with signed/unsigned. * arm64/*.S files use Microsoft-style ; comments, unsupported by GNU assembler. These were already converted in amd64/*.S files to //, but I propose a simpler fix to just strip them on the fly during the build with sed. * Missing _GetNativeSigSimdContext based on https://github.com/dotnet/runtime/blob/main/src/coreclr/pal/src/thread/context.cpp#L927 * Cpsr register is PState on Linux * wchar_t/char16_t mismatches when building with ICU. For now solved with #define wcslen PAL_wcslen etc in ChakraICU.h. It builds at least, though some Intl tests are failing. Note: binary with JIT crashes - this must be built with ./build.sh --no-jit. cmake already prints a warning that ARM64 JIT is only supported on Windows. --- CMakeLists.txt | 15 ++++-- build.sh | 4 +- ...rent_Frame.S => arm64_GET_CURRENT_FRAME.S} | 0 lib/Common/Core/CommonTypedefs.h | 2 +- lib/Common/arm64.h | 5 ++ lib/Runtime/Language/Arguments.h | 19 ++++++++ lib/Runtime/Language/SimdInt32x4Operation.cpp | 5 +- lib/Runtime/Library/JavascriptError.cpp | 2 +- lib/Runtime/PlatformAgnostic/ChakraICU.h | 14 ++++++ lib/Runtime/PlatformAgnostic/ChakraPlatform.h | 2 + .../Platform/Linux/PerfTrace.cpp | 2 + pal/inc/pal.h | 4 ++ pal/inc/pal_mstypes.h | 7 ++- pal/src/include/pal/context.h | 2 + pal/src/misc/sysinfo.cpp | 4 +- pal/src/thread/context.cpp | 48 +++++++++++++++++++ test/Number/toString.js | 6 ++- test/Number/toString_3.baseline | 4 -- 18 files changed, 127 insertions(+), 18 deletions(-) rename lib/Common/Common/arm64/{arm64_Get_Current_Frame.S => arm64_GET_CURRENT_FRAME.S} (100%) diff --git a/CMakeLists.txt b/CMakeLists.txt index beaf6298d2c..a48ff765721 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -54,6 +54,8 @@ if(CC_USES_SYSTEM_ARCH_SH OR NOT CHAKRACORE_BUILD_SH) set(CC_TARGETS_ARM_SH 1) elseif(CMAKE_SYSTEM_PROCESSOR STREQUAL "arm64") set(CC_TARGETS_ARM64_SH 1) + elseif(CMAKE_SYSTEM_PROCESSOR STREQUAL "aarch64") + set(CC_TARGETS_ARM64_SH 1) endif() unset(CC_USES_SYSTEM_ARCH_SH CACHE) endif() @@ -68,7 +70,7 @@ elseif(CC_TARGETS_ARM64_SH) add_definitions(-D_ARM64_=1) add_definitions(-D__arm64__=1) set(CC_TARGETS_ARM64 1) - set(CMAKE_SYSTEM_PROCESSOr "arm64") + set(CMAKE_SYSTEM_PROCESSOR "arm64") elseif(CC_TARGETS_X86_SH) set(CC_TARGETS_X86 1) set(CMAKE_SYSTEM_PROCESSOR "i386") @@ -293,6 +295,14 @@ elseif(CC_TARGETS_ARM64) if(CC_TARGET_OS_OSX) add_compile_options(-arch arm64) endif() + if (CC_TARGET_OS_LINUX) + # arm64 .S mostly use ;
