* alias.h (UNIQUE_BASE_VALUE_SP, UNIQUE_BASE_VALUE_ARGP, UNIQUE_BASE_VALUE_FP, UNIQUE_BASE_VALUE_HFP): Define. * alias.c (init_alias_targets): Use UNIQUE_BASE_VALUE_* macros instead of constants. * dse.c (record_store): Check for SP ADDRESS by comparing XWINT to UNIQUE_BASE_VALUE_SP instead of expecting XEXP to be stack_pointer_rtx. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@186623 138bc75d-0d04-0410-961f-82ee72b054a4
