llvm dev - Jun 2017 - Question about Prolog/Epilog Code Insertion

Hi All,

  When seeing the title "Prolog/Epilog Code Insertion", I'd expect
something about XXXFrameLowering.cpp
(particular about emitPrologue/emitEpilogue). But the document [1] is about
unwind. Is it placed at the right
place/section?

  Thanks.

Regards,

Please note the very beginning of the document: "Warning: This is a work in
progress."

This section is at the right place, but indeed it only seems to be talking about
one (minor) aspect of it which is the compact unwind info (which is only
relevant for apple platforms I think).
Unforunately there seems to be no general description yet about the passes tasks
and how it is achieving them, I think at the moment it's best to read the
sourcecode instead of the the CodeGenerator document...

I see, thanks.
