#### 9.27.9.4 Linking different FP ABI variants

Modules using the default FP ABI (no floating-point) can be linked with any other (singular) FP ABI variant.

Special compatibility support exists for O32 with the four double-precision FP ABI variants. The ‘`-mfpxx`’ FP ABI is specifically designed to be compatible with the standard double-precision ABI and the ‘`-mfp64`’ FP ABIs. This makes it desirable for O32 modules to be built as ‘`-mfpxx`’ to ensure the maximum compatibility with other modules produced for more specific needs. The only FP ABIs which cannot be linked together are the standard double-precision ABI and the full ‘`-mfp64`’ ABI with ‘`-modd-spreg`’.
