由于soft-float ABI不依赖硬件FPU,且可能不支持或不完全支持NEON指令集,因此在这种ABI下使用NEON intrinsics可能会导致编译错误或运行时问题。具体来说,编译器可能会因为无法将NEON intrinsics映射到相应的硬件指令而报错。 3. 说明如何通过编译选项-m来解决问题 为了解决这个问题,可以通过编译选项来指定使用hard-float A...
谢谢，abi改成v8后编译就通过了 2024-03-13 12:53来自上海
This is re-working of llvm#74460, which adds a soft-float ABI for AArch64. That was reverted because it causes errors when building the linux and fuchsia kernels. The problem is that GCC's implementation of the ABI compatibility checks when using the hard-float ABI on a target without ...

TheTag_ABI_FP_number_modeltells that it is using the standardIEEE 754format. Running it on aARM Cortex M4F(Kinetis K22) with single precision FPU shows this: Attribute Section: aeabi File Attributes Tag_CPU_name: "7E-M" Tag_CPU_arch: v7E-M ...
AAPCS stands for ARM Architecture Procedure Call Standard. You can read more details onARM website. There are also two other possible values for Tag_ABI_VFP_args: “AAPCS (base variant)” and “toolchain-specific”, but I’m not sure in which case they may be returned. ...
