This is the bt of how the C front-end is initializing these
declarations:
#0 set_builtin_decl (implicit_p=,
decl=,
fncode=) at ../../gcc/tree.h:5662
#1 def_builtin_1 (fncode=, name=,
fntype=, libtype=, both_p=,
fallback_p=, nonansi_p=false,
fnattrs=, implicit_p=true,
Following suggestions I'm testing the attached emitting the following
for long branches where LE cannot cover:
subslr, #1
bmi .L2

I see what's going on, originally this object-size text <= 20 test was
gated with target 'arm_thumb2'.
My patch to exclude LOB targets replaced that with
'arm_thumb2_ok_no_arm_v8_1_lob', unfortunatelly this is relying on
'arm_thumb2_ok' that has a different semantic compared to the original

What is going on is that in 'update_costs_from_allocno' we try to
identify the smallest mode using narrower_subreg_mode to then update the
costs.
The two modes involved here are E_DImode and E_VNx2QImode, cause these
are not ordered we ICE in 'paradoxical_subreg_p'.
Now I don't know if the
