RHEL people reported some errors when compiling rtla and rv with clang. The command line used to compile the tools is: $ make HOSTCC=clang CC=clang LLVM_IAS=1 The first problem is two unsupported flags passed to the compiler: -ffat-lto-objects and -Wno-maybe-uninitialized. They will be removed if the compile is clang. Also, the clang linker does not automatically recognize the -flto=auto option used at compilation time, so it is explicitly set. With the compiler working, it starts pointing to some warnings and errors about uninitialized variables, variable size, and an unused function. These problems are also fixed.
