[llvm-profgen] Unify output format of unsymbolized profiles

[wlei]

Summary

Unify the output format of raw profiles for hybrid sample and LBR only sample.

Add a test for show-relative-address=1?

[wlei]

llvm/test/tools/llvm-profgen/inline-cs-pseudoprobe.test

The default is true, so all others' test is for show-relative-address=1. Here is to test show-relative-address=0

I see. Makes sense.

Looks like we're changing (begin, end): count to begin-end: count. Curious any restriction on the format, or reason why one is chosen over the other? Is that purely to align with internal raw output from fleet profiler?

Yeah, no special reason, just to align with the internal raw output.

nit: show-xx is often used to output xx as extra. how about something like [show-]address-as-offset or use-offset. I'd change the term/variable name from relative address to offset too.

595

For CS raw profile (!CI.first.empty()), can we still keep the indentation like before for readability? Same for branch below. Otherwise it looks good.

Changed to use-offset

sounds good!

lgtm, thanks.
