architecture

constexpr arch_type spy::architecture

inlineconstexpr

Architecture reporting value.

The spy::architecture object can be compared to any other architecture related value to verify if the code being compiled is compiled for a given CPU architecture.

Additionally, any of the architecture related value are convertible to bool. They evaluates to true if they matches the correct architecture currently targeted.

Supported Value

Name	Architecture
spy::amd64	Intel X86-64 and similar architectures.
spy::arm	ARM.
spy::ppc	PowerPC.
spy::riscv	RISC-V.
spy::wasm	WASM pseudo-architecture.
spy::x86	Intel X86.

Example

#include <spy/spy.hpp>
#include <iostream>
 
int main()
{
  // Comparisons
  if      constexpr( spy::architecture == spy::x86_   ) std::cout << "This code is compiled for X86.\n";
  else if constexpr( spy::architecture == spy::amd64_ ) std::cout << "This code is compiled for X86-64.\n";
  else if constexpr( spy::architecture == spy::ppc_   ) std::cout << "This code is compiled for PowerPC.\n";
  else if constexpr( spy::architecture == spy::arm_   ) std::cout << "This code is compiled for ARM.\n";
  else if constexpr( spy::architecture == spy::riscv_ ) std::cout << "This code is compiled for RISC-V.\n";
 
  // Direct test
  if      constexpr( spy::x86_   ) std::cout << "This code is compiled for X86.\n";
  else if constexpr( spy::amd64_ ) std::cout << "This code is compiled for X86-64.\n";
  else if constexpr( spy::ppc_   ) std::cout << "This code is compiled for PowerPC.\n";
  else if constexpr( spy::arm_   ) std::cout << "This code is compiled for ARM.\n";
  else if constexpr( spy::riscv_ ) std::cout << "This code is compiled for RISC-V.\n";
