rtl.h (STRING_POOL_ADDRESS_P): Rename to DEFERRED_CONSTANT_P.
* rtl.h (STRING_POOL_ADDRESS_P): Rename to DEFERRED_CONSTANT_P.
* varasm.c (struct varasm_status): Add deferred_constants field.
(n_deferred_strings): Delete variable.
(n_deferred_constants): New #define.
(struct constant_descriptor_tree): Kill next and label fields.
(const_hash_table, MAX_HASH_TABLE): Delete.
(const_desc_htab): New static variable.
(const_hash): Rename const_desc_hash, and make it fit the
hashtab.h interface.
(const_desc_eq): New.
(const_hash_1, compare_constant): Const-ify arguments.
(build_constant_desc): Set DEFERRED_CONSTANT_P on all new
SYMBOL_REFs. Clarify comments. Don't set desc->label.
(output_constant_def): Do the lookup/insert using the
hashtab.h interface. Don't muck with n_deferred_constants or
DEFERRED_CONSTANT_P here.
Always call maybe_output_constant_def_contents.
(maybe_output_constant_def_contents): Take a pointer to the
descriptor, not the EXP and RTL separately. Return
immediately if this constant is not deferred. Defer output of
everything, except writable string constants. Update
n_deferred_constants here.
(output_constant_def_contents): Now takes just one argument,
an rtx. Clear DEFERRED_CONSTANT_P here.
(mark_constant_pool): Update for rename of n_deferred_strings.
(mark_constant): Don't clear DEFERRED_CONSTANT_P here.
(init_varasm_status): Clear p->deferred_constants.
(init_varasm_once): Call htab_create_ggc for const_desc_htab.
* gcc.dg/const-elim-1.c, gcc.dg/const-elim-2.c: New testcases.
