Detailed Description

The cpufeatures module offers properties for enabling or disabling specific CPU features. Use it if you want to override the compiler defaults for a given platform.

The compiler rules in the cpp module evaluate this module's properties and generate matching compiler flags. All properties in this module are of type bool and have the following semantics:

  • The default value undefined has no effect on the compiler command line.
  • If the value is true and the compiler has a flag to enable the feature, that flag is added to the command line if it is applicable to the current architecture. For example, enabling the property x86_sse2 would result in the GCC option -msse2.
  • If the value is false and the compiler has a flag to disable the feature, that flag is added to the command line if it is applicable to the current architecture. For example, disabling the property x86_sse2 would result in the GCC option -no-msse2.
