llvm dev - Sep 2019 - llvm-dev Digest, Vol 183, Issue 45

Hi Iulia,

Since there is no compilation error or error message about missing
'dummypass'
option, the best I can think of is missing re-build after pass
modification, or the
'hello.bc' has no function inside.

For me, it is quite hard to guess what is going wrong. The listed steps
seems to be
correct, although step 4. is not required: 'opt' is able to work on both
the bitcode
(.bc) and human-readable format (.ll)..


cheers,

Lorenzo
