[Bug middle-end/20177] New: ICE in schedule-insns for -O2 -fmodulo-sched

[janis at gcc dot gnu dot org]

The options "-O2 -fmodulo-sched" result in an internal compiler error on
powerpc*-linux for most benchmarks in SPEC CPU2000, and also for several
tests from gcc.c-torture/compile.  Failing tests from that directory with
-m32 are 20000403-1.c, 20040621-1.c, 920723-1.c, 920825-2.c, 931003-1.c,
961004-1.c, 961019-1.c, and 991214-1.c.  They all ICE in the same place with:
                                                                                
20000403-1.c:18: internal compiler error: in schedule_insns, at sched-rgn.c:2549
