[LLVMdev] DebugIR pass fails with an assert

[Konstantin Olkhovskiy]

Hi List,

My IR compiles fine and runs. I've tried to add DebugIR pass so
as to be able to debug and profile it (since source is an SQL query
all that I can debug and profile is IR itself).

When I tried to add it to pass manager I got the following assert:

Program received signal SIGABRT, Aborted.

What does "Literal structs never have names" mean? Do i have a problem
somewhere in the IR?
