OK.
Wait!
How is this failing for you? I'm not seeing that happen in my results.
The entire test output is here:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=124320#c0
I'm not seeing those errors on my thumb(1) runs.

So the question is why are we seeing different behaviours here?
I suppose your toolchain is uing -march=armv4t internally when you do not
define an arch and this architecture supports both -marm, -mthumb and a mix of
them.
Maybe my expression is not completly correct. Maybe it should be like this?
/* { dg-skip-if "inline assembler not compatible" { { arm_thumb1 || arm_thumb2 }
&& { ! arm_arm_ok } } } */
While writing this reply, I saw that you asked for what version of binutils I'm
using and it's 2.45.1.
Kind regards,

The inline assembler in the test case is incompatible with -mthumb for
arm-none-eabi toolchains.
