// A basic clang -cc1 command-line, and simple environment check.

// The tests here are similar to those in arm-toolchain.c, however
// these tests need to create symlinks to test directory trees in order to
// set up the environment and therefore shell support is required.
// UNSUPPORTED: system-windows

// If there is no GCC install detected then the driver searches for executables
// and runtime starting from the directory tree above the driver itself.
// The test below checks that the driver correctly finds the linker and
// runtime if and only if they exist.
