+This is an optimization hack which should only be present
+in a sparc 32bit driver of the compiler compiled with
+host/target/build sparc64-redhat-linux --with-cpu=v7.
+As long long HOST_WIDE_INT slows things down, we can have in
+addition to the sparc64-*/3.2/{cc1,cc1plus}
+sparc-*/3.2/{cc1,cc1plus} binaries which are suitable for compiling
+-m32 code only, but use long HOST_WIDE_INT.
