2020-10-18revamp ada.numerics.auxAlexandre Oliva15-477/+598
Instead of mapping elementary functions for all types to a single type, use the intrinsics available for the various base types. A new Ada.Numerics.Aux_Generic_Float is introduced to explicitly dispatch, based on the 'Digits attribute of the base type, to the various newly-added Aux_Short_Float, Aux_Float, Aux_Long_Float, or Aux_Long_Long_Float. The Aux_Short_Float unit is implemented in terms of the Aux_Float one, and the others rely on the elementary functions from the C Math library for float, double and long double types, respectively. An Aux_Linker_Options is added, and units that import intrinsics from libm/libc depend on it to provide the "-lm" linker option if needed. The option is provided by default, but there is an alternate version that doesn't, that is used for vxworks targets. The Aux variant that used to open-code Sin and Cos for the ancient ppc-darwin, because of insufficient precision in libc, is dropped, along with the alternate dummy body for Aux. Both are presumed no longer needed. The original Ada.Numerics.Aux is retained, for backward compatibility, as a wrapper for a newly-added Aux_Compat, that renames Aux_Long_Float, except on x86, in which an alternate version renames Aux_Long_Long_Float. Generic_Elementary_Functions and Generic_Complex_Types are adjusted to use Aux_Generic_Float, avoiding the type conversions and inefficiencies of computing results in higher precision than requested. Generic_Complex_Elementary_Functions is adjusted to enable an additional instance of the sincos optimization, even without -gnatn. for gcc/ada/ChangeLog * Makefile.rtl (GNATRTL_NONTASKING_OBJS): Compile Ada.Numerics child units Aux_Generic_Float, Aux_Long_Long_Float, Aux_Long_Float, Aux_Float, Aux_Short_Float, Aux_Compat, and Aux_Linker_Options.

This allows builds where a specific value is predefined, e.g. with a self spec, useful in environments where the system headers don't actually define that macro (e.g. vxworks 5 or 653). In addition, _WRS_VXWORKS_MINOR is only provided by the system headers when really meaningful, e.g. from 6.4 to 6.9.

2020-10-16Adjust BB vectorization SLP build heuristicsRichard Biener2-6/+45
This changes SLP def gathering to not fail due to mismatched def type but instead demote the def to external. This allows the new testcase to be vectorized in full (with GCC 10 it is not vectorized at all and with current trunk we vectorize only the store). This is important since with BB vectorization being applied to bigger pieces of code the chance that we mix internal and external defs for an operand that should end up treated as external (built from scalars) increases. 2020-10-16 Richard Biener <rguenther@suse.de> * tree-vect-slp.c (vect_get_and_check_slp_defs): For BB vectorization swap operands only if it helps, demote mismatches to external. * gcc.dg/vect/bb-slp-53.c: New testcase.

2020-10-16RISC-V: Handle implied extension in multilib-generatorKito Cheng1-4/+20
- -march has handle implied extension for a while, so I think multilib-generator should handle this well too. - Currently only add rule for D imply F. gcc/ChangeLog: * config/riscv/multilib-generator (IMPLIED_EXT): New. (arch_canonicalize): Update comment and handle implied extensions.

This refactors vect_get_and_check_slp_defs so that the ops and def_stmts arrays are filled for all stmts and operands even when we signal failure. This allows later changes for BB vectorization SLP discovery heuristics. 2020-10-16 Richard Biener <rguenther@suse.de> * tree-vect-slp.c (vect_get_and_check_slp_defs): First analyze all operands and fill in the def_stmts and ops entries.
