It seems the generated LLIntAssembly.h should have been changed, but it wasn't.
And the rebuild of LowLevelInterpreter.o was missing too because this header.

The second hash - generated from LLIntOffsetsExtractor - is different. But I don't know why, because LLIntOffsetsExtractor hasn't been changed at all.

offlineasm/asm.rb:
-------------------
...
inputHash =
    "// offlineasm input hash: " + parseHash(asmFile) +
    " " + Digest::SHA1.hexdigest(configurationList.map{|v| (v[0] + [v[1]]).join(' ')}.join(' ')) +
    " " + selfHash
...
