Constructor & Destructor Documentation

◆ modref_summary_lto()

modref_summary_lto::modref_summary_lto ( ) 
Summary for a single function which this pass produces.

References calls_interposable, false, loads, nondeterministic, NULL, retslot_flags, side_effects, static_chain_flags, stores, and writes_errno.

◆ ~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(), i, kill, kills, loads, nondeterministic, retslot_flags, side_effects, static_chain_flags, stores, and writes_errno.

Referenced by ipa_merge_modref_summary_after_inlining().

◆ 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.
