NAME
       architecture - architecture definition for ALPM based packages.


DESCRIPTION
       The architecture format is a custom string format that contains CPU
       instruction set architectures[1] and further identifiers and is used
       for representing the architecture of ALPM based packages.  This format
       is used in build scripts or file formats for package metadata (e.g. in
       PKGBUILD, BUILDINFO, PKGINFO) to describe the architecture of a
       package, or the architecture of dependency packages.

       The architecture format comprises values defined by convention.  The
       values are custom keywords, most of which are derived directly from CPU
       instruction set architectures[1] or specific microarchitectures.

       The architecture value must be covered by the set of alphanumeric
       characters and '_'.


EXAMPLES
       The below architecture values all relate to specific CPU instruction
       set architectures[1] or microarchitectures and can be used to specify a
       package architecture.  This usually means that packages of a specific
       architecture can only be used in a particular context.

              "any"

       A package can be used on any hardware as its contents are not specific
       to any architecture.

              "x86_64"

       A package can only be used on hardware compatible with the x86-64[2]
       instruction set version 1 and above (see x86-64 microarchitecture
       levels[3]).

              "x86_64_v2"

       A package can only be used on hardware compatible with the x86-64[2]
       instruction set version 2 and above (see x86-64 microarchitecture
       levels[3]).

              "x86_64_v3"

       A package can only be used on hardware compatible with the x86-64[2]
       instruction set version 3 and above (see x86-64 microarchitecture
       levels[3]).

              "x86_64_v4"

       A package can only be used on hardware compatible with the x86-64[2]
       instruction set version 4 and above (see x86-64 microarchitecture
       levels[3]).

              "i686"

       A package can only be used on hardware compatible with the IA-32[4]
       instruction set version 6 (aka. P6[5], or 'i686').  This architecture
       is considered legacy.

              "i486"

       A package can only be used on hardware compatible with the IA-32[4]
       instruction set version 4 (aka. i486[6]).  This architecture is
       considered legacy.

              "pentium4"

       A package can only be used on hardware compatible with the Pentium 4[7]
       microarchitecture.  This architecture is considered legacy.

              "armv7"

       A package can only be used on hardware compatible with the ARMv7
       architecture family[8].  This architecture is considered legacy.

              "armv8"

       A package can only be used on hardware compatible with the ARMv8
       architecture family[9].

              "aarch64"

       A package can only be used on hardware compatible with the AArch64[10]
       (64-bit execution state of the ARM architecture family[11]).

              "riscv64"

       A package can only be used on hardware compatible with the 64-bit
       variant of the RISC-V[12] instruction set architecture (ISA[13]).

              "loong64"

       A package can only be used on hardware compatible with the 64-bit
       variant of the LoongArch[14] instruction set architecture (ISA[13]).
