[PATCH] D35209: [ARM] Unify handling of M-Class system registers

[John Brawn via Phabricator via llvm-commits]

john.brawn added a comment.

ARMISelDAGToDAG.cpp and ARMAsmParser.cpp have essentially duplicate code for mapping the register name to the register enum, instead they should both call a function to handle it. I'm not sure where it would go though, maybe ARMBaseRegisterInfo? It would also make sense to move the reverse mapping (done by ARMInstPrinter.cpp) there as well so you only need to modify one file when adding a new register.
