Member Function Documentation

equal() [1/2]

bool expr_hasher::equal ( const expr * exp1, const expr * exp2 )

inlinestatic

Callback for hashtab.
Return nonzero if exp1 is equivalent to exp2.   

References exp_equiv_p(), expr::expr, gcc_assert, and expr::hash.

equal() [2/2]

bool pointer_hash< expr >::equal ( const value_type & existing, const compare_type & candidate )

inlinestaticinherited

hash() [1/2]

hashval_t expr_hasher::hash ( const expr * exp )

inlinestatic

Callback for hashtab.
Return the hash value for expression EXP.  We don't actually hash
here, we just return the cached hash value.   

References exp().

hash() [2/2]

hashval_t pointer_hash< expr >::hash ( const value_type & candidate )

inlinestaticinherited

is_deleted()

bool pointer_hash< expr >::is_deleted ( expr * e )

inlinestaticinherited

is_empty()

bool pointer_hash< expr >::is_empty ( expr * e )

inlinestaticinherited

mark_deleted()

void pointer_hash< expr >::mark_deleted ( expr *& e )

inlinestaticinherited

mark_empty()

void pointer_hash< expr >::mark_empty ( expr *& e )

inlinestaticinherited

remove()

void typed_noop_remove< expr * >::remove ( expr * & )

inlinestaticinherited

Remove doing nothing.
