Description Michael Saboff 2018-09-04 14:35:34 PDT 
If you successfully build JSC with:
$ Tools/Scripts/build-jsc --debug
and then try building with:
Tools/Scripts/build-jsc --debug ARCHS=i386
you'll get

offlineasm: No magic values found. Skipping assembly file generation.
Command /bin/sh failed with exit code 1

This is due to the build dependency checking seeing the derived file LLIntDesiredOffsets.h from the prior build and not generating one for the current architecture.
