Since we only have a Solaris version of the front-end (llvmgcc), we need to compile .c -> .ll files on a solaris machines in order to run the tests in Programs/. Doing this manually for all the C source files is really difficult. I added a flag called RUN_GCC_ONLY in test/Programs/Makefile.programs that will cause gmake to run only llvmgcc. Run the following in test/Programs to build .ll files for all the C source files. After that you can run the rest of the tests under Linux as before: gmake RUN_GCC_ONLY=1 --Vikram http://www.cs.uiuc.edu/~vadve
