+# Building a DSO with (unrecommended) non-pic pc-relative references
+# to a versioned symbol in a library got caught by an assert in
+# elf_cris_copy_indirect_symbol wherein the list of pc-relative
+# references wasn't merged, but simply asserted to be NULL before
+# copied to, on the merged-to (direct) symbol. For versioned symbols,
+# there was an "extra" copy made, to make a base-version symbol, where
+# the copied-from pc-relative list was NULL but the copied-to symbol
+# already had a list merged.
+
+# The list was used to emit warning messages, but incorrectly held the
+# relocation section for the reference, resulting in warnings being
+# emitted for any section with a pc-relative relocation.
+
+# The test checks that there's a warning message only for the
+# read-only sections section (.text) (not the read-write sections),
+# that the correct number of relocations is emitted and we also check
+# for the TEXTREL dynamic marker.
