multiple top level Main.main binders in STG

[Csaba Hruska]

Unfortunately it is dumped by my custom added code. (source code
<https://github.com/grin-tech/ghc-grin/blob/master/ghc-dump-core/GhcDump_StgConvert.hs#L82-L88>
)
I rerun my custom stg dump and it seems the unique values (in {--}
comments) are different.
How can I tell which is the real *Main.main* function?

Cheers,
Csaba

*Main.main {-r1550-}* =
  closure (F:) (B:
  void.040 {-040-}) {
  Main.main1 {-r16514-}
    GHC.Prim.void# {-021-}}

Main.main3 {-r16518-} =
  closure (F:) (B:
  void.040 {-040-}) {
  GHC.TopHandler.runMainIO1 {-r9161-}
    Main.main1 {-r16514-}
    GHC.Prim.void# {-021-}}

*Main.main {-0101-}* =
  closure (F:) (B:
  void.040 {-040-}) {
  Main.main3 {-r16518-}
    GHC.Prim.void# {-021-}}
