◆ bp_pack_string()

void bp_pack_string	(	struct output_block *	ob,
		struct bitpack_d *	bp,
		const char *	s,
		bool	persistent )

Output the '\0' terminated STRING to the string
table in OB.  Then put the index onto the bitpack BP.
When PERSISTENT is set, the string S is supposed to not change during
duration of the OB and thus OB can keep pointer into it.

◆ bp_pack_string_with_length()

void bp_pack_string_with_length	(	struct output_block *	ob,
		struct bitpack_d *	bp,
		const char *	s,
		unsigned int	len,
		bool	persistent )

Output STRING of LEN characters to the string table in OB.  Then
put the index into BP.
When PERSISTENT is set, the string S is supposed to not change during
duration of the OB and thus OB can keep pointer into it.

◆ lto_append_block()

void lto_append_block ( struct lto_output_stream * obs )

Routines for saving various data types to a file stream.  This deals
   with various data types like strings, integers, enums, etc.

◆ streamer_string_index()

static unsigned streamer_string_index	(	struct output_block *	ob,

static

Return index used to reference STRING of LEN characters in the string table
in OB.  The string might or might not include a trailing '\0'.
Then put the index onto the INDEX_STREAM.
When PERSISTENT is set, the string S is supposed to not change during
duration of the OB and thus OB can keep pointer into it.
