Function Documentation

void gcov_enable_events

(

void

)

gcov_enable_events - enable event reporting through gcov_event()

Turn on reporting of profiling data load/unload-events through the gcov_event() callback. Also replay all previous events once. This function is needed because some events are potentially generated too early for the callback implementation to handle them initially.

Definition at line 92 of file base.c.

void gcov_event	(	enum gcov_action	action,
		struct gcov_info *	info
	)

Definition at line 733 of file fs.c.

void gcov_info_add	(	struct gcov_info *	dest,
		struct gcov_info *	source
	)

gcov_info_add - add up profiling data : profiling data set to which data is added : profiling data set which is added

Adds profiling counts of to .

Definition at line 86 of file gcc_3_4.c.

struct gcov_info* gcov_info_dup ( struct gcov_info *  info )

read

gcov_info_dup - duplicate profiling data set : profiling data set to duplicate

Return newly allocated duplicate on success, NULL on error.

Definition at line 124 of file gcc_3_4.c.

void gcov_info_free

(

struct gcov_info *

info

)

gcov_info_free - release memory for profiling data set duplicate : profiling data set duplicate to free

Definition at line 172 of file gcc_3_4.c.

int gcov_info_is_compatible	(	struct gcov_info *	info1,
		struct gcov_info *	info2
	)

gcov_info_is_compatible - check if profiling data can be added : first profiling data set : second profiling data set

Returns non-zero if profiling data can be added, zero otherwise.

Definition at line 74 of file gcc_3_4.c.

void gcov_info_reset

(

struct gcov_info *

info

)

gcov_info_reset - reset profiling data to zero : profiling data set

Definition at line 56 of file gcc_3_4.c.

Definition at line 273 of file gcc_3_4.c.

struct gcov_iterator* gcov_iter_new ( struct gcov_info *  info )

read

gcov_iter_new - allocate and initialize profiling data iterator : profiling data set to be iterated

Return file iterator on success, NULL otherwise.

Definition at line 247 of file gcc_3_4.c.

int gcov_iter_next

(

struct gcov_iterator *

iter

)

gcov_iter_next - advance file iterator to next logical record : file iterator

Return zero if new position is valid, non-zero if iterator has reached end.

Definition at line 317 of file gcc_3_4.c.

void gcov_iter_start

(

struct gcov_iterator *

iter

)

gcov_iter_start - reset file iterator to starting position : file iterator

Definition at line 282 of file gcc_3_4.c.

int gcov_iter_write	(	struct gcov_iterator *	iter,
		struct seq_file *	seq
	)

gcov_iter_write - write data for current pos to seq_file : file iterator : seq_file handle

Return zero on success, non-zero otherwise.
