How to debug SYCLomatic —— use command line

Step 1: Create a folder named syclomatic_home, then clone SYCLomatic and create new folders named c2s_install (to put the output executable files) and build (to put the build progress files) in it. The file tree maybe like this:

syclomatic_home
|-- build
|-- c2s_install
|-- SYCLomatic

Step 2: Build project:

cd build
cmake -G Ninja -DCMAKE_INSTALL_PREFIX=../c2s_install -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_TARGETS_TO_BUILD="X86;NVPTX" ../SYCLomatic/llvm
ninja install-c2s

Step 3: Debug c2s (assume cuda file is in “test” folder):

gdb build/bin/c2s

(gdb) set args --out-root=test test/test.cu
(gdb) r
