AVR: Provide built-ins for strlen where the string lives in some AS.
This patch adds built-in functions __builtin_avr_strlen_flash,
__builtin_avr_strlen_flashx and __builtin_avr_strlen_memx.
Purpose is that higher-level functions can use __builtin_constant_p
on strlen without raising a diagnostic due to -Waddr-space-convert.
gcc/
* config/avr/builtins.def (STRLEN_FLASH, STRLEN_FLASHX)
(STRLEN_MEMX): New DEF_BUILTIN's.
* config/avr/avr.cc (avr_ftype_strlen): New static function.
(avr_builtin_supported_p): New built-ins are not for AVR_TINY.
(avr_init_builtins) <strlen_flash_node, strlen_flashx_node,
strlen_memx_node>: Provide new fntypes.
(avr_fold_builtin) [AVR_BUILTIN_STRLEN_FLASH]
[AVR_BUILTIN_STRLEN_FLASHX, AVR_BUILTIN_STRLEN_MEMX]: Fold if
possible.
* doc/extend.texi (AVR Built-in Functions): Document
__builtin_avr_strlen_flash, __builtin_avr_strlen_flashx,
__builtin_avr_strlen_memx.
libgcc/
* config/avr/t-avr (LIB1ASMFUNCS): Add _strlen_memx.
* config/avr/lib1funcs.S <L_strlen_memx, __strlen_memx>: Implement.
