2017-02-09arc/gcc: Better creation of __NPS400__ defineAndrew Burgess3-2/+14
The __NPS400__ define is currently created in CPP_SPEC unlike the other target defines, which are created in arc-c.def. Further, the current __NPS400__ define is (currently) only created when -mcpu=nps400 is passed, which is fine, except that if GCC is configured using --with-cpu=nps400 then the -mcpu option is not required and the __NPS400__ define will not be created. This commit moves the __NPS400__ define into arc-c.def inline with all of the other target defines, and removes the code in CPP_SPEC that used to create the define. In order to support the creation of the define in arc-c.def, a new TARGET_NPS400 macro is created in arc.h. gcc/ChangeLog: * config/arc/arc-c.def: Add __NPS400__ definition. * config/arc/arc.h (CPP_SPEC): Don't define __NPS400__ here. (TARGET_NPS400): Define. From-SVN: r245294
2017-02-09gcc/arc: Make arc_selected_cpu globalAndrew Burgess5-53/+74
Currently we only make the base_architecture globally available, this means we can tell if we have selected arc700/archs/etc but it's not possible to tell if the user has selected a specific cpu variant, for example nps400. One problem this causes is, for example, in arc-c.def, if we want to add an __NPS400__ define then we need a flag we can check to determine if this is the right thing to do. In this commit the arc_selected_cpu variable (previously local within arc.c) has been made global. Two other variables arc_base_cpu and arc_selected_arch have been deleted, all of this information can be found within (or through) arc_selected_cpu. All uses of arc_base_cpu and arc_selected_arch have been updated. This commit does not introduce any new defines (like __NPS400__), this is just a restructuring commit. The declaration of arc_selected_cpu has moved into arc-arch.h, in contrast to the declaration of arc_base_cpu which was previously in arc.h. This avoids a compilation issue when building libgcc, as the structure and enums declared in arc-arch.h are not included for libgcc then declaring an arc_selected_cpu (a struct type) in arc.h would result in an unknown struct error. We got away with this for arc_base_cpu as that was an enum type. The declaration of arc_selected_cpu in arc.h could have been wrapped in a '#ifndef IN_LIBGCC2 ... #endif', but it felt neater to simply move the declaration into arc-arch.h. gcc/ChangeLog: * config/arc/arc-arch.h (arc_arch_t): Move unchanged to earlier in file. (arc_cpu_t): Change base_architecture field, arch, to a arc_arc_t pointer, arch_info. (arc_cpu_types): Fill the arch_info field with a pointer into the arc_arch_types table.

2017-02-06sched: Do not move expensive insns speculatively (PR68664)Segher Boessenkool6-6/+62
Scheduling should never move very expensive instructions to places they are executed more frequently. This patch fixes that, reducing the execution time of c-ray by over 40% (I tested on a BE Power7 system). This introduces a new target hook sched.can_speculate_insn which returns whether the scheduler is allowed to speculate a given instruction. The rs6000 implementation disallows all divide and square root instructions.
