From a83403892ac33484c0a830a21313fdf2473bcd0f Mon Sep 17 00:00:00 2001 From: Matthias Braun Date: Tue, 30 Oct 2018 23:28:27 +0000 Subject: MachineOperand/MIParser: Do not print debug-use flag, infer it The debug-use flag must be set exactly for uses on DBG_VALUEs. This is so obvious that it can be trivially inferred while parsing. This will reduce noise when printing while omitting an information that has little value to the user. The parser will keep recognizing the flag for compatibility with old `.mir` files.
