Using systemc-clang

After successfully compiling systemc-clang, it is possible to run the tool, but it requires several additional arguments. Assuming that the current path is in the directory that contains the systemc-clang binary, the tool can be run as follows. :: $ ./systemc-clang test.cpp – __STDC_CONSTANT_MACROS -D__STDC_LIMIT_MACROS -I<path-to-llvm-install>/lib/clang/10.0.0/include/ -I/usr/include -I$<path-to-systemc>/include -x c++ -w -c

It is important to note that systemc-clang requires the arguments to pass into it the location for the clang includes, and SystemC includes.

Useful scripts to execute systemc-clang

The distribution provides the following useful scripts to execute systemc-clang.

• run.sh: executes systemc-clang.

• run-gdb.sh: executes gdb with systemc-clang.

Both of these scripts require setting some environment variables. Most of these are defined in the following scripts to make it easier for users. * paths.sh: A bash shell script to set the appropriate environment variables. * paths.fish: A fish shell script to set the appropriate environment variables.

Specifically, these scripts require the user to set the following variables. These can be changed in the file itself.

• LLVM_INSTALL_DIR: This points to the directory where clang is installed.

• SYSTEMC: This points to the directory where SystemC is installed.

• SYSTEMC_CLANG_BUILD_DIR: This points to where systemc-clang was built.

Once the appropriate environment variables are set, the scripts used to run systemc-clang can be executed successfully. :: $ scripts/run.sh test.cpp
