Date: Wed Aug 25 19:31:48 2021 +0530 [android] Update to NDK 23 The latest Long Term Support NDK finally removed binutils, including the bfd/gold linkers and libgcc. This simplifies our Android support, including making lld the default linker for Android. Disable three reflection tests that now fail, likely related to issues with swift-reflection-dump and switching to lld. diff --git a/swift/CMakeLists.txt b/swift/CMakeLists.txt index 73fc7fe0ebc..5487dbc83cd 100644 --- a/swift/CMakeLists.txt +++ b/swift/CMakeLists.txt @@ -180,6 +180,8 @@ set(CLANG_COMPILER_VERSION "" CACHE STRING # build environment. if(LLVM_USE_LINKER) set(SWIFT_USE_LINKER_default "${LLVM_USE_LINKER}") +elseif(${SWIFT_HOST_VARIANT_SDK} STREQUAL ANDROID) + set(SWIFT_USE_LINKER_default "lld") elseif(CMAKE_SYSTEM_NAME STREQUAL Windows AND NOT CMAKE_HOST_SYSTEM_NAME STREQUAL Windows) set(SWIFT_USE_LINKER_default "lld") elseif(CMAKE_SYSTEM_NAME STREQUAL Darwin) @@ -306,8 +308,8 @@ set(SWIFT_ANDROID_API_LEVEL "" CACHE STRING set(SWIFT_ANDROID_NDK_PATH "" CACHE STRING "Path to the directory that contains the Android NDK tools that are executable on the build machine") -set(SWIFT_ANDROID_NDK_GCC_VERSION "" CACHE STRING - "The GCC version to use when building for Android.
