--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
At -O0 we get
t3.c: In function 'main':
t3.c:21:5: error: 'asm' operand has impossible constraints
21 | __asm__ (""
| ^~~~~~~
likely because there's not enough registers to pass in 'arr' (and we need a FP
to allocate arr). At -O1 it looks like we think we can manage but do not make
progress reloading.
So confirmed, a diagnostic would be nice.
