From 46a43556db23edb514f190cc03b0ce7f68d40534 Mon Sep 17 00:00:00 2001 From: Mehdi Amini Date: Wed, 4 Mar 2015 18:43:29 +0000 Subject: Make DataLayout Non-Optional in the Module Summary: DataLayout keeps the string used for its creation. As a side effect it is no longer needed in the Module. This is "almost" NFC, the string is no longer canonicalized, you can't rely on two "equals" DataLayout having the same string returned by getStringRepresentation(). Get rid of DataLayoutPass: the DataLayout is in the Module The DataLayout is "per-module", let's enforce this by not duplicating it more than necessary. One more step toward non-optionality of the DataLayout in the module. Make DataLayout Non-Optional in the Module Module->getDataLayout() will never returns nullptr anymore.
