But this is pointless because herd will select a good and sufficient .cat file from the assembly-language litmus test itself. This commit therefore removes the -model argument to herd, allowing herd to figure the CPU family out itself. Note that the user can override herd's choice using the "--herdopts" argument to the scripts. Suggested-by: Luc Maranget Signed-off-by: Paul E.
