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. (X86_TARGET_PAIRS): Drop dummy body for Aux. Use x86 version of Aux_Compat. (X86_64_TARGET_PAIRS): Likewise. (LIBGNAT_TARGET_PAIRS): On VxWorks, select the nolibm variants.

The following combination are fixed with this patch: $ cat bug.c int main(){ return 0; } $ arm-none-eabi-gcc -mcpu=cortex-m55 -mfloat-abi=soft bug.c -c $ arm-none-eabi-gcc -mcpu=cortex-m55 -mfloat-abi=soft -march=armv8.1-m.main+mve bug.c -c Before this patch for above combinations: cc1: warning: switch '-mcpu=cortex-m55' conflicts with '-march=armv8.1-m.main' switch After this patch for above combinations no warning/errors. gcc/ChangeLog: 2020-10-16 Srinath Parvathaneni <srinath.parvathaneni@arm.com> PR target/97327 * config/arm/arm.c (fp_bitlist): Add isa_bit_mve_float to FP bits array. gcc/testsuite/ChangeLog: PR target/97327 * gcc.target/arm/mve/intrinsics/pr97327.c: New test.
