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 )

◆ ggc_maybe_mx()

static void ggc_cache_remove< rtx_def * >::ggc_maybe_mx ( rtx_def * & )
inlinestaticinherited

◆ ggc_mx()

static void ggc_remove< rtx_def * >::ggc_mx ( rtx_def * & p)
inlinestaticinherited

◆ hash() [1/2]

hashval_t const_double_hasher::hash ( rtx x)
static 
Returns a hash code for X (which is really a CONST_DOUBLE).

References CONST_DOUBLE_HIGH, CONST_DOUBLE_LOW, CONST_DOUBLE_REAL_VALUE, GET_MODE, real_hash(), and TARGET_SUPPORTS_WIDE_INT.
