[PATCH] D41104: Set the NoRecurse attribute for the dbg intrinsics.

[Matt Davis via Phabricator via llvm-commits]

mattd created this revision.

Fixes PR34696

This patch sets the NoRecurse attribute for the debug intrinsics:
dbg.declare
dbg.value
dbg.addr

The purpose of this change is to not have the debugger intrinsics influence code generation. Previously, if a function made a call to the llvm.dbg.value intrinsic, that caller function would not be optimized with the norecurse attribute, even if it was truly not a recursive function.
