+Subject: [PATCH 1/2] ld/arc: Provide the .tdata symbol.
+
+When creating local dynamic tls access we rely on a .tdata symbol being
+available to link against. Normally, this is fine, as content is placed
+into the .tdata section the linker makes a .tdata symbol available and
+all is fine.
+
+However, these linker created section symbols only exist for input
+sections, not output sections, so, when we assemble with
+-fdata-sections, and the content is placed not into '.tdata', but into
+sections like, '.tdata.variable' we end up in a situation where there is
+no input section called '.tdata', and so the linker does not create a
+symbol called '.tdata' for us, at which point the link fails.
+
+The solution it to have the linker script explicitly provide the symbol
+'.tdata', this should ensure that the symbol is always available.
+
+ld/ChangeLog:
+
+ * scripttempl/arclinux.sc (.tdata): Provide the .tdata symbol.
+
+ld/testsuite/ChangeLog:
+
+ * ld/testsuite/ld-arc/arc.exp: Run new test.
+ * ld/testsuite/ld-arc/tls-data-sections.d: New file.
+ * ld/testsuite/ld-arc/tls-data-sections.s: New file.
