From 2f01fd99eb8c8ab3db9aba72c4f00e31e9e60a05 Mon Sep 17 00:00:00 2001 From: Stephen Tozer Date: Wed, 1 May 2024 16:50:12 +0100 Subject: [RemoveDIs] Load into new debug info format by default in LLVM (#89799) This patch enables parsing and creating modules directly into the new debug info format. Prior to this patch, all modules were constructed with the old debug info format by default, and would be converted into the new format just before running LLVM passes. This is an important milestone, in that this means that every tool will now be exposed to debug records, rather than those that run LLVM passes. As far as I've tested, all LLVM tools/projects now either handle debug records, or convert them to the old intrinsic format. There are a few unit tests that need updating for this patch; these are either cases of tests that previously needed to set the debug info format to function, or tests that depend on the old debug info format in some way. There should be no visible change in the output of any LLVM tool as a result of this patch, although the likelihood of this patch breaking downstream code means an NFC tag might be a little misleading, if not technically incorrect: This will probably break some downstream tools that don't already handle debug records. If your downstream code breaks as a result of this change, the simplest fix is to convert the module in question to the old debug format before you process it, using `Module::convertFromNewDbgValues()`.
