我正在转换VDSP 编译器的 FFT 算法到裸机应用程序在核心 B 上运行并让 uclinux 在核心 A 上运行。我有一个链接错误,但我没有了解它来自哪里:

代码如下所示:

.var _Ret_Add =0;
.var _Save_R7 =0;

.l1.text;
.global _Compute_Cycle_Count;
.对齐8;
_Compute_Cycle_Count: P0.L = _Ret_Add;

    P0.L = _Save_R7;

    [P0] = R7;

I'm converting the FFT algo for VDSP compiler to bare metal app to run on core B and have uclinux running on core A. I've a linking error I do not understand where it come from:

P0.H = _Ret_Add;
R3 = RETS;
[P0] = R3;

    P0.L = _Save_R7;

您的代码中没有 GNU 汇编程序可以理解的 _Ret_Add_Save_R7 声明。您应该将其从 VDSP asm 移植到 GNU asm:

_Ret_Add: .int 0;

或者如果您希望保持向后兼容:

.if defined (__GNUC__)
_Ret_Add:
.int 0;
.else
.var _Ret_Add =0;
.endif

请查看 这个

You have no declaration of _Ret_Add and _Save_R7 in your code to be understood by GNU assembler. You should port it from VDSP asm to GNU asm:

_Ret_Add: .int 0;

or maybe if you prefer keep it backwards compatible:

.if defined (__GNUC__)
_Ret_Add:
.int 0;
.else
.var _Ret_Add =0;
.endif

Take a look at this.
