From-SVN: r8480
1994-11-15(flow_delete_insn): New function.Doug Evans1-45/+119
(find_basic_blocks): Call it to physically delete insns in unreachable blocks. When scanning blocks after dead ones, start scanning after the dead one (not at the dead one). If there are lots of unreachable blocks, make another pass to squeeze them out (this reduces memory usage in some pathalogical cases by a significant amount without resorting to sparse matrices). (propagate_block): Make code a bit more efficient (for example, no need to test `loop_depth' for each insn, just notes). From-SVN: r8440

value via invisible pointer. From-SVN: r6748

instruction of each basic block. From-SVN: r6500
1994-02-03Add prototypes for static functions.Richard Kenner1-114/+173
(uses_reg_or_mem): New function. (find_basic_block): Some cleanups; eliminate shadowed variables. Look for REG_LABEL notes in all insns and allow for multiple such. Don't delete labels in forced_labels. Generalize test for computed jumps. (find_auto_inc): OFFSET should be HOST_WIDE_INT. (mark_used_regs): Put decls of parms in parm order. (find_use_as_address): PLUSCONST should be HOST_WIDE_INT. From-SVN: r6477
