- Subject: [patch][commit] Typo in utils-sim.scm Generating Decoder
Hi,
I've committed this patch which corrects a typo in the generation of the
decoder. The generated code was intended to shift 'entire_insn' to the
right when the insn length is less than the base insn size.
Tested on an internal port which exposed the problem.

* utils-sim.scm (-gen-decode-insn-entry): Generated code should shift
'entire_insn' not 'base_insn'.
