For every data constructor GHC generates an "info table", and its label is "C_con_info" I think. The first word of the data constructor heap object points to the info table.
The info table has data that describes the object layout (for the GC), and a little piece of code that says simply "return", used if someone enters that object. More details about info tables in many GHC papers Simon | -----Original Message----- | From: ghc-devs [mailto:[email protected]] On Behalf Of Karel | Gardas | Sent: 13 March 2014 18:50 | To: ghc-devs | Subject: Where to find GHC.Types.D#_con_info | | Hello, | | I'm trying to debug few issues in SPARC NCG, now dealing with double | floats issue.
