Bug ID: 80017
Summary: [5/6/7 Regression] ICE: Max. number of generated
reload insns per insn is achieved (90)
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Keywords: ra
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: bernds at gcc dot gnu.org, vmakarov at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux-gnu
Target: x86_64-linux-gnu
Build: x86_64-linux-gnu
Starting from 4.9.0 we ICE on:
$ gcc /home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/pr37434-1.c
-march=pentium -m32 -msse -c
/home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/pr37434-1.c: In
function ‘Set_AC4R_SETUP_I’:
/home/marxin/Programming/gcc/gcc/testsuite/gcc.target/i386/pr37434-1.c:12:1:
internal compiler error: Max. number of generated reload insns per insn is
achieved (90)
}

0xd18074 lra_constraints(bool)

../../gcc/lra.c:2392
0xcac6b2 do_reload
../../gcc/ira.c:5451

../../gcc/ira.c:5635
and probably the same issue:
$ cat ice.c
void a ()
{
short b;
__attribute__ ((__vector_size__ (8 * sizeof (short)))) short c = {b};
}
$ gcc ice.c -c -m32 -march=athlon-mp
ice.c: In function ‘a’:
ice.c:5:1: internal compiler error: Max. number of generated reload insns per
insn is achieved (90)
