-This patch to LLVM is required by the developers of the Extempore language.
-The following explanation was posted to the extemporelang@googlegroups.com
-mailing list:
-
-"There is an assumption in the parser that all definitions occur within the
-same compilation unit - i.e. the parser has local state about what has been
-parsed in this unit of work.  Extempore obviously does lots of little units
-rather than one big unit and this causes problems for named types that were
-defined in another unit - which they always are.  The patch simply checks the
-current module to see if the type has been previously defined, and intervenes
-appropriately if it has."

-Date: Fri, 18 Oct 2019 10:34:07 +0200
-Subject: [PATCH] input/item: sort before attaching slaves
-
-The order of readdir() is completely filesystem dependent.
-
-Slaves should be attached using the same order across multiple OSses/access
-modules.
-
-This fixes the test_libvlc_slaves on some system when the entry order from
-readdir() is different.
-
-This patch need to be backported to VLC 3.0.
