[PATCH] D61609: [llv] Handle missing debug info when updating sample counts

[David Li via Phabricator via llvm-commits]

davidxl added inline comments.


================
Comment at: llvm/test/Transforms/SampleProfile/entry_counts_missing_dbginfo.ll:3
+; ModuleID = 'temp.bc'
+; This is a test similar to entry_counts_cold.ll. The key differences are:

----------------
Can you explain exactly what happens that triggers the div by zero? when bar is inlined?
