Selects the target floating-point unit (FPU) architecture. If you specify this option it overrides any implicit FPU set by the --cpu option. The assembler produces an error if the FPU you specify explicitly is incompatible with the CPU. Floating-point instructions also produce either errors or warnings if assembled for the wrong target FPU.

The assembler sets a build attribute corresponding to name in the object file. The linker determines compatibility between object files, and selection of libraries, accordingly.

Selects no floating-point architecture. This makes your assembled object file compatible with object files built with any FPU.

Selects hardware floating-point unit conforming to architecture VFPv3.

Selects hardware floating-point unit conforming to architecture VFPv3 with half-precision floating-point extension.

Selects hardware floating-point unit conforming to architecture VFPv3-D16.

Selects hardware floating-point unit conforming to architecture VFPv3-D16 with half-precision floating-point extension.

Selects hardware floating-point unit conforming to architecture VFPv2.

Selects software floating-point linkage. This is the default if you do not specify a --fpu option and the --cpu option selected does not imply a particular FPU.

Selects a floating-point library with software floating-point linkage that uses VFP instructions.

This is otherwise equivalent to using --fpu vfpv2.

Selects a floating-point library with software floating-point linkage that uses VFP instructions.

This is otherwise equivalent to using --fpu vfpv3.

Selects a floating-point library with software floating-point linkage that uses VFP instructions.

This is otherwise equivalent to using --fpu vfpv3_fp16.

Selects a floating-point library with software floating-point linkage that uses VFP instructions.

This is otherwise equivalent to using --fpu vfpv3_d16.

Selects a floating-point library with software floating-point linkage that uses VFP instructions.

This is otherwise equivalent to using --fpu vfpv3_d16_fp16.
