re PR target/55897 ([avr] Allocate __memx data to .progmemx.data)
PR target/55897
* config/avr/avr.h (ADDR_SPACE_COUNT): New enum.
(avr_addrspace_t): Add .section_name field.
* config/avr/avr.c (progmem_section): Use ADDR_SPACE_COUNT as
array size.
(avr_addrspace): Same. Initialize .section_name. Remove last
NULL entry. Put __memx into .progmemx.data.
(progmem_section_prefix): Remove.
(avr_asm_init_sections): No need to initialize progmem_section.
(avr_asm_named_section): Use avr_addrspace[].section_name to get
section name prefix.
(avr_asm_select_section): Ditto. And use get_unnamed_section to
retrieve the progmem section.
* avr-c.c (avr_cpu_cpp_builtins): Use ADDR_SPACE_COUNT as loop
boundary to run over avr_addrspace[].
(avr_register_target_pragmas): Ditto.
