--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This boils down to -O2 -mavx512f
typedef int V __attribute__ ((vector_size (8)));
V
foo (char x)
{
return (V) __builtin_ia32_vec_init_v8qi (x, x, x, x, x, x, x, x);
}
I think, except that for some weird reasons in this shorter testcase
we get:
pr59835.c: In function âfooâ:
pr59835.c:7:1: internal compiler error: Max. number of generated reload insns
per insn is achieved (90)
ICE and with the larger one LRA just keeps iterating forever.
