Member Function Documentation

equal() [1/2]

bool const_double_hasher::equal ( rtx x, rtx y )

static

Returns true if the value represented by X (really a ...)
is the same as that represented by Y (really a ...)

equal() [2/2]

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

hash() [1/2]

hashval_t const_double_hasher::hash ( rtx x )

static

Returns a hash code for X (which is really a CONST_DOUBLE).
