4.41 Default selection of hardware or software floating-point support
The default target FPU architecture is derived from use of the --cpu option.
If the processor specified with --cpu has a VFP coprocessor, the default target FPU architecture is the VFP architecture for that processor. For example, the option --cpu ARM1136JF-S implies the option --fpu vfpv2.
If a VFP coprocessor is present, VFP instructions are generated. If there is no VFP coprocessor, the compiler generates code that makes calls to the software floating-point library fplib to carry out floating-point operations. fplib is available as part of the standard distribution of the ARM compilation tools suite of C libraries.
根据说明书我在misc control选项那里添加 --fpu vfpv2之后,整个程序都不能正常运行了。
