fwprop.c (update_df): Support width and offset parameters of df_ref_create.
2008-03-05 Kenneth Zadeck <zadeck@naturalbridge.com>
* fwprop.c (update_df): Support width and offset parameters of
df_ref_create.
* ra-conflict.c (mark_reg_store, clear_reg_in_live,
global_conflicts): Change DF_REF_EXTRACT to either
DF_REF_ZERO_EXTRACT or DF_REF_SIGN_EXTRACT. Change
DF_REF_STRICT_LOWER_PART to DF_REF_STRICT_LOW_PART.
* df-scan.c (df_ref_record, df_defs_record,
df_ref_create_structure, df_def_record_1, df_uses_record,
df_get_conditional_uses, df_get_call_refs, df_insn_refs_collect,
df_bb_refs_collect, df_entry_block_defs_collect,
df_exit_block_uses_collect): Support new width and offset fields.
(ref_extract_pool): New storage pool.
(df_free_ref): New function.
(df_reg_chain_unlink, df_free_collection_rec,
df_sort_and_compress_refs): Call df_free_ref.
(df_ref_equal_p, df_ref_compare): Compare offset and width fields
of df_ref_extract.
(df_ref_create_structure): Allocate df_ref_extract if offset and
width fields are used.
(df_def_record_1): Get offset and width from ZERO_EXTRACT.
(df_uses_record): Get offset and width from ZERO_EXTRACT
and SIGN_EXTRACT.
* global.c (build_insn_chain): Change DF_REF_EXTRACT to either
DF_REF_ZERO_EXTRACT or DF_REF_SIGN_EXTRACT. Change
DF_REF_STRICT_LOWER_PART to DF_REF_STRICT_LOW_PART.
* df.h (df_ref_flags): Change DF_REF_EXTRACT to either
DF_REF_ZERO_EXTRACT or DF_REF_SIGN_EXTRACT. Change
DF_REF_STRICT_LOWER_PART to DF_REF_STRICT_LOW_PART.
(df_ref_extract): New structure.
(DF_REF_WIDTH, DF_REF_OFFSET): New macros.
(df_ref_create): Add width and offset parameters.
