paperchalice · 2023-12-04T07:53:12Z

Here is the list of the renamed passes:

callbrprepare -> callbr-prepare
dwarfehprepare -> dwarf-eh-prepare
flattencfg -> flatten-cfg
loweratomic -> lower-atomic
lowerinvoke -> lower-invoke
lowerswitch -> lower-switch
winehprepare -> win-eh-prepare
targetir -> target-ir
targetlibinfo -> target-lib-info

Legacy passes are not affected.

Just rename some of them, some of them are combined with llc or legacy passes, which are not ready for testing.

Some more words to describe/justify the change might be helpful. (and/or a link to a discourse thread where this has been more broadly discussed) given the churn this would produce, I guess? (& the renamings look sufficiently independent maybe they should be committed separately - though I guess reviewing the overall concept in one place is probably good)

What was the consensus here? I think we are free to just break any names in the codegen pipeline. I would start with just those without aliases

These renames look ok to me.
