看来插件模式不能用寄存器R15，这个比较麻烦，我先看看。 https://groups.google.com/g/golang-codereviews/c/124cVR_LDTo https://github.com/golang/go/issues/43661

emmansun commented 1 year ago

Hi @fzzf678 , 目前 sm2/sm3/sm9/zuc 的amd64汇编实现，都使用了R15寄存器，由于AMD64寄存器本来就比较少：

x86 has just 8 general-purpose registers available (eax, ebx, ecx, edx, ebp, esp, esi, edi). x64 extended them to 64 bits (prefix "r" instead of "e") and added another 8 (r8, r9, r10, r11, r12, r13, r14, r15). Since some of x86's registers have special implicit meanings and aren't really used as general-purpose (most notably ebp and esp), the effective increase is even larger than it seems.

所以，真要使用插件模式，目前唯有使用purego编译选项（-tags=purego），而且目前只支持整个项目的purego编译选项，不支持分sm2/sm3/sm4/sm9/zuc等的编译选项（这个可以改进）。

fzzf678 commented 1 year ago

@emmansun thks，使用 purego 选项可以编译通过。目前看来是只有这一种解决方法了吧

@emmansun thks，使用 purego 选项可以编译通过。目前看来是只有这一种解决方法了吧

是的，只是性能就也是purego的性能了，目前可以改进的是，增加一些算法级别的编译选项（sm2purego/sm3purego/sm9purego/zucpurego，或者定义一个plugin编译选项），这样插件模式也能使用amd64汇编实现的sm4等。如果不能接受这种编译选项下的性能，建议使用非插件模式。
