Children packages provide operations on this types, -- one child package covers one instruction set. Types declarations are -- specific for GNAT compiler. The way how subprograms are defined is also -- GNAT specific, it allows to highly optimize code and replace one function -- by one instruction in most cases. ------------------------------------------------------------------------------ with Ada.Unchecked_Conversion; with Interfaces; package Matreshka.SIMD.Intel is pragma Pure; -- 256-bit types type v32qi is array (1 .. 32) of Interfaces.Integer_8; for v32qi'Alignment use 32; pragma Machine_Attribute (v32qi, "vector_type"); pragma Machine_Attribute (v32qi, "may_alias"); type v16hi is array (1 .. 16) of Interfaces.Integer_16; for v16hi'Alignment use 32; pragma Machine_Attribute (v16hi, "vector_type"); pragma Machine_Attribute (v16hi, "may_alias"); type v8si is array (1 .. 8) of Interfaces.Integer_32; for v8si'Alignment use 32; pragma Machine_Attribute (v8si, "vector_type"); pragma Machine_Attribute (v8si, "may_alias"); type v4di is array (1 .. 4) of Interfaces.Integer_64; for v4di'Alignment use 32; pragma Machine_Attribute (v4di, "vector_type"); pragma Machine_Attribute (v4di, "may_alias"); type v8sf is array (1 .. 8) of Interfaces.IEEE_Float_32; for v8sf'Alignment use 32; pragma Machine_Attribute (v8sf, "vector_type"); pragma Machine_Attribute (v8sf, "may_alias"); type v4df is array (1 .. 4) of Interfaces.IEEE_Float_64; for v4df'Alignment use 32; pragma Machine_Attribute (v4df, "vector_type"); pragma Machine_Attribute (v4df, "may_alias"); -- 128-bit types type v16qi is array (1 .. 16) of Interfaces.Integer_8; for v16qi'Alignment use 16; pragma Machine_Attribute (v16qi, "vector_type"); pragma Machine_Attribute (v16qi, "may_alias"); type v8hi is array (1 .. 8) of Interfaces.Integer_16; for v8hi'Alignment use 16; pragma Machine_Attribute (v8hi, "vector_type"); pragma Machine_Attribute (v8hi, "may_alias"); type v4si is array (1 .. 4) of Interfaces.Integer_32; for v4si'Alignment use 16; pragma Machine_Attribute (v4si, "vector_type"); pragma Machine_Attribute (v4si, "may_alias"); type v2di is array (1 .. 2) of Interfaces.Integer_64; for v2di'Alignment use 16; pragma Machine_Attribute (v2di, "vector_type"); pragma Machine_Attribute (v2di, "may_alias"); type v4sf is array (1 .. 4) of Interfaces.IEEE_Float_32; for v4sf'Alignment use 16; pragma Machine_Attribute (v4sf, "vector_type"); pragma Machine_Attribute (v4sf, "may_alias"); type v2df is array (1 .. 2) of Interfaces.IEEE_Float_64; for v2df'Alignment use 16; pragma Machine_Attribute (v2df, "vector_type"); pragma Machine_Attribute (v2df, "may_alias"); -- 64-bit types type v8qi is array (1 .. 8) of Interfaces.Integer_8; for v8qi'Alignment use 8; pragma Machine_Attribute (v8qi, "vector_type"); pragma Machine_Attribute (v8qi, "may_alias"); type v4hi is array (1 .. 4) of Interfaces.Integer_16; for v4hi'Alignment use 8; pragma Machine_Attribute (v4hi, "vector_type"); pragma Machine_Attribute (v4hi, "may_alias"); type v2si is array (1 .. 2) of Interfaces.Integer_32; for v2si'Alignment use 8; pragma Machine_Attribute (v2si, "vector_type"); pragma Machine_Attribute (v2si, "may_alias"); type v1di is array (1 .. 1) of Interfaces.Integer_64; for v1di'Alignment use 8; pragma Machine_Attribute (v1di, "vector_type"); pragma Machine_Attribute (v1di, "may_alias"); -- Type conversion operations. function To_v16hi is new Ada.Unchecked_Conversion (v4df, v16hi); function To_v4df is new Ada.Unchecked_Conversion (v16hi, v4df); function To_v16qi is new Ada.Unchecked_Conversion (v8hi, v16qi); function To_v8hi is new Ada.Unchecked_Conversion (v4si, v8hi); function To_v8hi is new Ada.Unchecked_Conversion (v2di, v8hi); function To_v4si is new Ada.Unchecked_Conversion (v8hi, v4si); function To_v2di is new Ada.Unchecked_Conversion (v4si, v2di); function To_v2di is new Ada.Unchecked_Conversion (v8hi, v2di); function To_v8qi is new Ada.Unchecked_Conversion (v2si, v8qi); function To_v4hi is new Ada.Unchecked_Conversion (v8qi, v4hi); function To_v4hi is new Ada.Unchecked_Conversion (v2si, v4hi); function To_v2si is new Ada.Unchecked_Conversion (v4hi, v2si); function To_v2si is new Ada.Unchecked_Conversion (v8qi, v2si); end Matreshka.SIMD.Intel;
