2017-10-11Enable ifunc attribute by default for ARM GNU/LinuxAdhemerval Zanella2-1/+6
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. Tested compilation of glibc (in conjunction with a glibc patch to support using the attribute on ARM) with build-many-glibcs.py (with a patch to add a armv7 variant which enables multiarch). I have not run the GCC tests for ARM. * config.gcc (default_gnu_indirect_function): Default to yes for arm*-*-linux* with glibc. From-SVN: r253635

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

2017-10-10Require wi::to_wide for treesRichard Sandiford86-559/+896
The wide_int routines allow things like: wi::add (t, 1) to add 1 to an INTEGER_CST T in its native precision. But we also have: wi::to_offset (t) // Treat T as an offset_int wi::to_widest (t) // Treat T as a widest_int Recently we also gained: wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC This patch therefore requires: wi::to_wide (t) when operating on INTEGER_CSTs in their native precision. This is just as efficient, and makes it clearer that a deliberate choice is being made to treat the tree as a wide_int in its native precision. This also removes the inconsistency that a) INTEGER_CSTs in their native precision can be used without an accessor but must use wi:: functions instead of C++ operators b) the other forms need an explicit accessor but the result can be used with C++ operators. It also helps with SVE, where there's the additional possibility that the tree could be a runtime value. 2017-10-10 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * wide-int.h (wide_int_ref_storage): Make host_dependent_precision a template parameter.
