re PR middle-end/33699 (missing optimization on const addr area store)
PR middle-end/33699
* target.h (struct gcc_target): Fix indentation. Add
const_anchor.
* target-def.h (TARGET_CONST_ANCHOR): New macro.
(TARGET_INITIALIZER): Use it.
* cse.c (CHEAPER): Move it up to the other macros.
(insert): Rename this ...
(insert_with_costs): ... to this. Add cost parameters. Update
function comment.
(insert): New function. Call insert_with_costs.
(compute_const_anchors, insert_const_anchor, insert_const_anchors,
find_reg_offset_for_const, try_const_anchors): New functions.
(cse_insn): Call try_const_anchors. Adjust cost of src_related
when using a const-anchor. Call insert_const_anchors.
* config/mips/mips.c (mips_set_mips16_mode): Set
targetm.const_anchor.
* doc/tm.texi (Misc): Document TARGET_CONST_ANCHOR.
