+
+llvm supports specifying a non-standard layout where each project lies in its

-Subject: [PATCH] [clang] fix undefined behaviour in
- RawComment::getFormattedText()
-
-Summary:
-Calling `back()` and `pop_back()` on the empty string is undefined
-behavior [1,2].
-
-The issue manifested itself as an uncaught `std::out_of_range` exception
-when running `clangd` compiled on RHEL7 using devtoolset-9.

-Subject: [PATCH] [remark][diagnostics] [codegen] Fix PR44896
-
-This patch fixes PR44896. For IR input files, option fdiscard-value-names
-should be ignored as we need named values in loadModule().
-Commit 60d3947922 sets this option after loadModule() where valued names
-already created. This creates an inconsistent state in setNameImpl()
-that leads to a seg fault.
-This patch forces fdiscard-value-names to be false for IR input files.
-
-This patch also emits a warning of "ignoring -fdiscard-value-names" if
-option fdiscard-value-names is explictly enabled in the commandline for
-IR input files.

+Subject: [PATCH 5/6] [PATCH][clang] Partially Revert "scan-view: Remove
+ Reporter.py and associated AppleScript files"
+
+This reverts some of commit dbb01536f6f49fa428f170e34466072ef439b3e9.
+
+The Reporter module was still being used by the ScanView.py module and deleting
+it caused scan-view to fail.  This commit adds back Reporter.py but removes the
+code the references the AppleScript files which were removed in
+dbb01536f6f49fa428f170e34466072ef439b3e9.
