1; RUN: opt -S %s -passes=sample-profile -sample-profile-file=%S/Inputs/entry_counts_cold.prof -profile-sample-accurate | FileCheck %s2; ModuleID = 'temp.bc'3; This is a test similar to entry_counts_cold.ll. The key differences are:4; - we want profile-sample-accurate. Normally, that would trigger resetting function entry counts to 0, and then update5; them based on the sample profile (SampleProfile::runOnFunction).6; - we don't have debug info for the function. This means we can't match sample counts in the profile to locations in this function.7; When we attempt to update its profile info (at the end of SampleProfile::runOnModule - llvm::updateProfileCallee), we'll call8; updateProfWeight with a 0 priorEntryCount, which will result in a division by 0.9;10; We're using @bar and the call to @baz.11;12; Currently, the test just ensures opt doesn't ICE13source_filename = "temp.c"14target datalayout = "e-m:o-i64:64-f80:128-n8:16:32:64-S128"15target triple = "x86_64-apple-macosx10.14.0"16 17;
