--fpu=name (fromelf)

D1.29 --fpu=name (fromelf)

Specifies the target FPU architecture.

To obtain a full list of FPU architectures use the --fpu=list option.

Syntax

--fpu=name

Where name is the name of the target FPU architecture. Specify --fpu=list to list the supported FPU architecture names that you can use with --fpu=name.

The default floating-point architecture depends on the target architecture.

Note:

Software floating-point linkage is not supported for AArch64 state.

Usage

This option selects disassembly for a specific FPU architecture. It affects how fromelf interprets the instructions it finds in the input files.

If you specify this option, it overrides any implicit FPU option that appears on the command line, for example, where you use the --cpu option.

Any FPU explicitly selected using the --fpu option always overrides any FPU implicitly selected using the --cpu option.

Default

The default target FPU architecture is derived from use of the --cpu option.

If the CPU you specify with --cpu has a VFP coprocessor, the default target FPU architecture is the VFP architecture for that CPU.
