rtx_constant_pool Struct Reference

Collaboration diagram for rtx_constant_pool:

Data Fields
class constant_descriptor_rtx *	first
class constant_descriptor_rtx *	last
hash_table< const_rtx_desc_hasher > *	const_rtx_htab
HOST_WIDE_INT	offset

Detailed Description

Used in the hash tables to avoid outputting the same constant
twice.  Unlike 'struct constant_descriptor_tree', RTX constants
are output once per function, not once per file.   

??? Only a few targets need per-function constant pools.  Most
can use one per-file pool.  Should add a targetm bit to tell the
difference.
