+    	PR target/58595
+    	* config/arm/arm.c (arm_tls_symbol_p): Remove.
+    	(arm_legitimize_address): Call legitimize_tls_address for any
+    	arm_tls_referenced_p expression, handle constant addend.  Call it
+    	before testing for !TARGET_ARM.
+    	(thumb_legitimize_address): Don't handle arm_tls_symbol_p here.
+    
+    	* gcc.dg/tls/pr58595.c: New test.
