failed to retarget asm to x86-64

Hi, guys. Sorry for bothering you.

I wrote a c program that just prints "Hello world" and used **arm-linux-gnueabihf** to compile it into **arm**.
Then, I used retdec-decompiler to decompile it.
I failed to recompile the result.

I used clang to compile .bc file.
I guess "first defined here" can be bypassed with "--allow-multiple-definition".
But, could you tell me how to fix the error **undefined reference to `__asm_adr'** ?

Thank you very much.

Here is the code.
>#include
int main()
{
printf("Hello world\n");
}

info of target.

> hello: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0, BuildID[sha1]=9207f3df03ef3fc0edeba44efd0ed893beff3fe2, not stripped

Reproduce the reported failure by compiling the generated .bc with clang and review the target-triple warning, duplicate _init/_fini/_start definitions, and unresolved __asm_adr symbol. The issue provides no repository file or test entry point; done would require determining whether cross-target recompilation is supported and documenting or fixing the resulting linker errors.
