Subject: [PATCH] 	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.
