| ; This is a test similar to entry_counts_cold.ll. The key differences are: |
| ; - we want profile-sample-accurate. Normally, that would trigger resetting function entry counts to 0, and then update |
| ; them based on the sample profile (SampleProfile::runOnFunction). |
| ; - 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. |
| ; When we attempt to update its profile info (at the end of SampleProfile::runOnModule - llvm::updateProfileCallee), we'll call |
| ; updateProfWeight with a 0 priorEntryCount, which will result in a division by 0. |
| ; |
| ; We're using @bar and the call to @baz. |
| ; |
| ; Currently, the test just ensures opt doesn't ICE |
