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...
您好,如果没有写明使用什么abi,默认是arm64-v8a和armeabi-v7a均进行构建 报错是因为armeabi-v7a不支持neon头文件 如果只想构建abi是arm64-v8a,可在模块级build-prodile.json5中设置abiFilters类型 1 1楼回复于2024-03-13 00:56 来自广东 树厥 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 ...
