From 6174fd7ed09e9d183d84fb3485a714c5b0c67e4a Mon Sep 17 00:00:00 2001 From: Sebastian Pop Date: Wed, 8 Aug 2012 17:45:43 +0000 Subject: enable Hexagon target from cmake This patch allows us to use cmake to specify a cross compiler for Hexagon. In particular, the patch adds a missing case for the target Hexagon in cmake/config-ix.cmake, and it moves LLVM_DEFAULT_TARGET_TRIPLE and TARGET_TRIPLE variables from cmake/config-ix.cmake to the toplevel CMakeLists.txt to make them available at configure time. Here is the command line that I have used to test my patches: $ cmake -G Ninja -D BUILD_SHARED_LIBS:BOOL=ON -D LLVM_TARGETS_TO_BUILD:STRING=Hexagon -D TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_DEFAULT_TARGET_TRIPLE:STRING=hexagon-unknown-linux-gnu -D LLVM_TARGET_ARCH:STRING=hexagon-unknown-linux-gnu -D LLVM_ENABLE_PIC:BOOL=OFF .. $ ninja check git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@161504 91177308-0d34-0410-b5e6-96231b3b80d8 --- CMakeLists.txt | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) (limited to 'CMakeLists.txt') diff --git a/CMakeLists.txt b/CMakeLists.txt index ed230ae..a3aee58 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -116,8 +116,15 @@ option(LLVM_ENABLE_FFI "Use libffi to call external functions from the interpret set(FFI_LIBRARY_DIR "" CACHE PATH "Additional directory, where CMake should search for libffi.so") set(FFI_INCLUDE_DIR "" CACHE PATH "Additional directory, where CMake should search for ffi.h or ffi/ffi.h") -set(LLVM_TARGET_ARCH "host" - CACHE STRING "Set target to use for LLVM JIT or use \"host\" for automatic detection.") +set(LLVM_TARGET_ARCH "host" CACHE STRING + "Set target to use for LLVM JIT or use \"host\" for automatic detection.") + +# By default, we target the host, but this can be overridden at CMake +# invocation time. +set(LLVM_DEFAULT_TARGET_TRIPLE "${LLVM_TARGET_ARCH}" CACHE STRING + "Default target for which LLVM will generate code." ) +set(TARGET_TRIPLE "${LLVM_DEFAULT_TARGET_TRIPLE}" CACHE STRING + "Default target for which LLVM will generate code." ) option(LLVM_ENABLE_THREADS "Use threads if available."
