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.
