rtl.texi (MEM_SIZE_KNOWN_P): Document.
gcc/
* doc/rtl.texi (MEM_SIZE_KNOWN_P): Document.
(MEM_SIZE): Change from returning an rtx to returning a HOST_WIDE_INT.
* rtl.h (MEM_SIZE_KNOWN_P): New macro.
(MEM_SIZE): Return a HOST_WIDE_INT rather than an rtx.
* emit-rtl.h (set_mem_size): Take a HOST_WIDE_INT rather than an rtx.
(clear_mem_size): Declare.
* emit-rtl.c (set_mem_size): Take a HOST_WIDE_INT rather than an rtx.
(clear_mem_size): New function.
* alias.c (ao_ref_from_mem): Adjust uses of MEM_SIZE, using
MEM_SIZE_KNOWN_P to test whether the size is known, and MEM_SIZE
to get a HOST_WIDE_INT size. Adjust calls to set_mem_size,
passing a HOST_WIDE_INT rather than an rtx. Use clear_mem_size
to clear the size.
