我尝试在代码中插入第35行和第36行,但是当我尝试使用llc生成.o文件时出现错误。
35 %12 = ptrtoint i32* %1 to i64
36 call void @__Storemy(i32 10, i64 %12)
37 store i32 %10, i32* %1
38 br label %18
错误信息:
Instruction does not dominate all uses!
%12 = ptrtoint i32* %1 to i64
call void @__StoreTo(i32 15, i64 %12)
Broken module found, compilation aborted!

这是此功能的整个 IR:

我找不到此代码有任何问题,任何人都可以给我一些建议吗?
