Remove useless register keywords
This patch removes useless register keywords from several backends and one
spot in the Ada FE.
2021-05-26 Jakub Jelinek <jakub@redhat.com>
gcc/
* config/epiphany/epiphany.c (epiphany_print_operand_address): Remove
register keywords.
* config/microblaze/microblaze.c (microblaze_legitimize_address,
call_internal1,
microblaze_option_override, print_operand): Likewise.
* config/microblaze/microblaze.md (call_internal_plt,
call_value_intern_plt, call_value_intern): Likewise.
* config/arm/aout.h (ASM_OUTPUT_ALIGN): Likewise.
* config/iq2000/iq2000.md (call_internal1, call_value_internal1,
call_value_multiple_internal1): Likewise.
* config/bfin/bfin.c (symbolic_reference_mentioned_p): Likewise.
gcc/ada/
* init.c (__gnat_error_handler): Remove register keyword.
