Hi I got two confusions when trying to use global_asm and integrate some assembly codes.

  1. I got the internal compiler error listed as below;
  2. The error messages look wierd with arrows confusingly pointing to blankets or some existing labels. (If I just misunderstood them please correct me)

Any Help would be appreciated very much :D

Code

use core::arch::global_asm;

global_asm!(include_str!("./arm/func.S"), options(raw));
global_asm!(include_str!("./bug/bug.s"), options(raw));

fn main() {

}

func.S:

#include "macro_a.S"
#include "macro_b.S"
#include "macro_c.S"

You can't use #include with assembly code used by global_asm!. This requires running a C pre-processor over the assembly code which can only be done with build.rs.

However the assertion failure is still a real issue in the compiler.

Is it not allowed to use as comments?

It won't include macro_a.s, which is what the originally assembly code intended to do. It will instead just be parsed as a comment and ignored.

Maybe try this one? main.zip

I try to update the rustc version, but the error still exists. I use file and xxd to check the assembly files that can and can't reproduce the ICE, and find some differences: their encodings differ with terminators, one with \r\n (with ICE) and another with only \r (without ICE). Also, error information about unrecognized instruction mnemonic compiling with assembly files with \r\n displays arrows confusingly pointing to blankets, but for files with only \r, error info is the same as yours'. Arrows point to the beginning of the tags or instructions, which makes sense in a way.

I don't know whether the terminator is the root cause. Hope that could help figure it out.

The new meta info I get after updating the rustc version:
