 %description
-The compiler-rt project is a part of the LLVM project. It provides
-implementation of the low-level target-specific hooks required by
-code generation, sanitizer runtimes and profiling library for code
-instrumentation, and Blocks C language extension.
+The compiler-rt project provides highly tuned implementations of the
+low-level code generator support routines like "__fixunsdfdi" and other
+calls generated when a target doesn't have a short sequence of native
+instructions to implement a core IR operation.
