NAME

Acme::Alien::__cpu_model - Provides the __cpu_model symbol

SYNOPSIS

use ExtUtils::MakeMaker;
WriteMakefile(
    # ...

    LIBS => Acme::Alien::__cpu_model->libs,
);

DESCRIPTION

Older GCCs, and some recent Clangs, like my Apple LLVM 8.0.0 (clang-800.0.42.1), lack the __cpu_model builtin, which some libraries like GLFW depend on.

This package provides a useless definition, that allows packages using GLFW on such a system to link. As long you don't use any function, that depends on the exact value of __cpu_model, all should be well.

IMPLEMENTATION

const struct __processor_model {
  unsigned int __cpu_vendor;
  unsigned int __cpu_type;
  unsigned int __cpu_subtype;
  unsigned int __cpu_features[1];
} __cpu_model;

An archive is created with a single (non-COMMON) __cpu_model symbol
