+Subject: [PATCH] Driver: Add a gcc equivalent triple to the list of triples to

+
+There are some gcc triples, like x86_64-redhat-linux, that provide the
+same behavior as a clang triple with a similar name (e.g.
+x86_64-redhat-linux-gnu).  When searching for a gcc install, also search

-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.

+# Gating testplans for Clang
+
+The tests for clang are in a separate repo: https://src.fedoraproject.org/tests/clang
+This directory should contain only fmf plans (such as build-gating.fmf) which import
+the tests from the tests repo. This can be done using the "url" parameter of the
+plan's "discover" step. Reference: https://tmt.readthedocs.io/en/stable/spec/plans.html#fmf
