commit f76ea6220a5f0d59f5f43d3d6d526f1fd09b90f7
Author: Euan Haahr <euanhaahrmail2@gmail.com>
Date: Fri Feb 5 22:51:14 2021 +0000
Various fixes for LLVM 12 compatibility (1351)
Removed use of options.PrintMachineCode since this has been removed as
of llvm 12. Converted uses of DebugLoc::get to DILocation::get since
it has been deprecated and removed as of llvm 12.
PrintMachine code will only be used if llvm is lower than version 12.
TODO: Needs to be re-added in the new way for LLVM12. (LG just doesn't
have time to figure this out right now.)
Pass adjustment as various things have been deprecated or changed
names. (LG)
