df.h (df_mw_hardreg): Remove "loc" field.
gcc/
* df.h (df_mw_hardreg): Remove "loc" field.
* df-scan.c (df_ref_record): Don't set it. Remove redundant
local variable.
* df-problems.c (df_whole_mw_reg_unused_p): New function,
split out from df_set_unused_notes_for_mw. Return false for
partial references. Assert that mw_reg is a REG when returning true.
(df_set_unused_notes_for_mw): Use it. Use mw_reg instead of *loc.
(df_whole_mw_reg_dead_p): New function, split out from
df_set_dead_notes_for_mw. Return false for partial references.
Assert that mw_reg is a REG when returning true.
(df_set_dead_notes_for_mw): Use it. Use mw_reg instead of *loc.
Remove redundant bitmap check.
