Constructor & Destructor Documentation

modref_summary_lto()

modref_summary_lto::modref_summary_lto

(

)

Summary for a single function which this pass produces.   

~modref_summary_lto()

modref_summary_lto::~modref_summary_lto

(

)

References ggc_delete(), loads, and stores.

Member Function Documentation

dump()

void modref_summary_lto::dump

(

FILE *

out

)

Dump summary.   

References arg_flags, calls_interposable, dump_lto_records(), ggc_alloc(), i, kill, kills, loads, nondeterministic, retslot_flags, side_effects, static_chain_flags, stores, and writes_errno.

useful_p()

bool modref_summary_lto::useful_p	(	int	ecf_flags,
		bool	check_flags = true )

Return true if lto summary is potentially useful for optimization.
If CHECK_FLAGS is false assume that arg_flags are useful.
