Hi, Like the .ctors array, __do_global_dtors_aux_fini_array_entry and __frame_dummy_init_array_entry arrays need a specific alignment. This patch fixes those two arrays. This patch fixes the bootstrap on mips64-linux-gnu.
Bootstrapped on mips64-linux-gnu. Bootstrapped and tested on x86-linux-gnu with no regressions. Thanks, Andrew Pinski libgcc/ChangeLog: * crtstuff.c (__do_global_dtors_aux_fini_array_entry): Align to the size of func_ptr. (__frame_dummy_init_array_entry): Likewise.
