2017-10-12rs6000: Improve iselSegher Boessenkool5-57/+57
This removes output_isel. Instead, the define_insn's now output the isel instructions directly. It adds a reg_or_zero operand predicate, too, because the reg_or_cint predicate is too lax here. Also use it in the "reversed" variants of the instructions. * config/rs6000/predicates.md (zero_constant, all_ones_constant): Move up in file. (reg_or_cint_operand): Fix comment.

Similar to other architectures with IFUNC binutils/glibc support, this patch enables the ifunc attribute for ARM GNU/Linux. Although not required for build master GLIBC, the intention is to allow refactor its assembly implementation to C.

2017-10-11rs6000: insn_costSegher Boessenkool3-0/+94
This adds an implementation of the insn_cost hook to rs6000. This implementations is very minimal (so far). It is mostly based on how many machine instructions are generated by an RTL insn, and it also looks at the instruction type. Floating point insns are costed as if all machine instructions it generates are floating point; the other insns are treated as if all but one are integer insns (and one is the specified type). Load instructions are treated as costing twice as much, and load locked and sync insns as three times as much (just like the original costs), and integer div and mul are handled as well. Each define_insn (etc.) can set a "cost" attribute to override this general cost. With optimization for size, the cost is set equal to the value of the "length" attribute. With this, the majority of cost differences between old and new are where the old was wrong. Also, benchmarks show a slight win (if anything). Some refinements are obviously needed. * config/rs6000/rs6000.c (TARGET_INSN_COST): New. (rs6000_insn_cost): New function. * config/rs6000/rs6000.md (cost): New attribute. From-SVN: r253624
