--fpu=name

9.51 --fpu=name

Specifies the target FPU architecture.

Syntax

--fpu=name
Where name is one of:
VFPv3
Selects a hardware vector floating-point unit conforming to architecture VFPv3. VFPv3 is backwards compatible with VFPv2 except that VFPv3 cannot trap floating-point exceptions.
VFPv3_FP16
Selects a hardware vector floating-point unit conforming to architecture VFPv3 that also provides the half-precision extensions.
VFPv3_D16
Selects a hardware vector floating-point unit conforming to VFPv3-D16 architecture.
VFPv3_D16_FP16
Selects a hardware vector floating-point unit conforming to VFPv3-D16 architecture, that also provides the half-precision extensions.
VFPv4
Selects a hardware floating-point unit conforming to the VFPv4 architecture.
VFPv4_D16
Selects a hardware floating-point unit conforming to the VFPv4-D16 architecture.
FPv4-SP
Selects a hardware floating-point unit conforming to the single precision variant of the FPv4 architecture.
FPv5_D16
Selects a hardware floating-point unit conforming to the FPv5-D16 architecture.
FPv5-SP
Selects a hardware floating-point unit conforming to the single precision variant of the FPv5 architecture.
SoftVFP
Selects software floating-point support where floating-point operations are performed by a floating-point library, fplib. This is the default if you do not specify a --fpu option, or if you select a CPU that does not have an FPU.
To obtain a full list of FPU architectures use the --fpu=list option.
