This series creates pattern_cost and insn_cost functions that together replace the existing insn_rtx_cost function.
pattern_cost is like the old insn_rtx_cost function; insn_cost takes an actual rtx_insn * as input, not just a pattern. Also a targetm.insn_cost is added, which targets can use to implement a more exact cost more easily. The combine patch is pretty gross (but functional), it needs some refactoring (to not call recog so often). The rs6000 patch is very much a work in progress. How does this look? Is this the right direction? Segher Segher Boessenkool (5): Rename existing insn_cost to insn_sched_cost Replace insn_rtx_cost with insn_cost and pattern_cost combine: Use insn_cost instead of pattern_cost everywhere Add targetm.insn_cost hook rs6000: Implement insn_cost hook gcc/cfgrtl.c | 7 +++---- gcc/combine.c | 40 +++++++++++++++++++++++++++++----------- gcc/config/rs6000/rs6000.c | 14 ++++++++++++++ gcc/doc/tm.texi | 12 ++++++++++++ gcc/doc/tm.texi.in | 2 ++ gcc/dse.c | 2 +- gcc/haifa-sched.c | 14 +++++++------- gcc/ifcvt.c | 12 ++++++------ gcc/rtl.h | 3 ++- gcc/rtlanal.c | 16 ++++++++++++++-- gcc/sched-int.h | 2 +- gcc/sched-rgn.c | 4 ++-- gcc/sel-sched-ir.c | 2 +- gcc/target.def | 14 ++++++++++++++ 14 files changed, 108 insertions(+), 36 deletions(-) -- 1.9.3
