Compiler

Definition

Retrieves compiler information at run time as the compiler's name and version, as well as compilation options. It uses the intrinsic functions compiler_options and compiler_version from the module iso_fortran_env.

Features

• Automatic detection of compiler name, vendor and version at runtime
• Detection of compilation options and debug/release profile
• Support for a wide range of Fortran compilers (gfortran, ifort/ifx, nvfortran, nagfor, flang, etc.)
• Compile-time fallback detection using preprocessor macros
• Consistent output formatting for benchmark reports

Examples

program test_compiler_info
  use benchmark_steps_compiler
  use benchmark_workflow
 
  type(workflow) :: w
 
  call w%add(compiler())
  call w%run()
end program

Another example showing direct usage:

use benchmark_steps_compiler
 
type(compiler) :: ci
character(:), allocatable :: opts
 
ci = build_compilerinfo(compiler_gcc, compiler_version())
opts = compiler_options()
 
print *, 'Compiler:', trim(ci%name), trim(ci%version)
print *, 'Options:', opts
