FTR, I'm running into this ICE when attempting to build the Linux Kernel for
arm64.
Hello.
Thanks for the report.
More specifically:

Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.
I don't have a reduced testcase for this, but I thought I'd check if this is
known/being worked on before filing a bug.
It's not a known issue. Please attach me the used command line and
pre-processed source file
(using -E option).
You might try arc-elf gcc.dg/pr91734.c. I've been behind and just peeked at the
arc-elf regressions in the tester a moment ago and it's tripping this as well.
Thanks for it. This one is one another example where an optimization level
affects
a target option:
$ cat x.c
__attribute__((optimize ("O3"))) void
f1 ()
{
}
int
main ()
{
return 0;
}
11682 if (ptr1->x_TARGET_ALIGN_CALL != ptr2->x_TARGET_ALIGN_CALL)
11683 internal_error ("%<global_options%> are modified in local context");
set here:
{ OPT_LEVELS_3_PLUS_SPEED_ONLY, OPT_malign_call, NULL, 1 },
I'm going to add this to exception list.
