cse.c (cse_end_of_basic_block): Make static.
2004-02-18 Paolo Bonzini <bonzini@gnu.org>
* cse.c (cse_end_of_basic_block): Make static.
* local-alloc.c (function_invariant_p): Move to
reload1.c.
* loop.c (libcall_other_reg, record_excess_regs):
Make static.
* reload1.c (function_invariant_p): Moved here
from local-alloc.c, made static.
* rtl.h (cse_end_of_basic_block, function_invariant_p,
libcall_other_reg, record_excess_regs): Remove
declarations.
