            Bug ID: 97360
           Summary: ICE in range_on_exit
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: amodra at gmail dot com
  Target Milestone: ---

during GIMPLE pass: evrp
/home/alan/src/gcc/gcc/testsuite/gcc.target/powerpc/mma-double-test.c: In
function 'MMA':
/home/alan/src/gcc/gcc/testsuite/gcc.target/powerpc/mma-double-test.c:186:1:
internal compiler error: in range_on_exit, at gimple-range.cc:931

The types involved are:
 <integer_type 0x7ffff6622bd0 __vector_quad sizes-gimplified unsigned PXI
    size <integer_cst 0x7ffff653c660 type <integer_type 0x7ffff652d1f8
bitsizetype> constant 512>
    unit-size <integer_cst 0x7ffff661f180 type <integer_type 0x7ffff652d150
sizetype> constant 64>
    align:512 warn_if_not_align:0 symtab:0 alias-set -1 canonical-type
0x7ffff6622bd0 precision:512 min <integer_cst 0x7ffff661f150 0> max
<integer_cst 0x7ffff6625000
0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff>
    pointer_to_this <pointer_type 0x7ffff6644000>>

and:
 <integer_type 0x7ffff6622b28 public unsigned XI
    size <integer_cst 0x7ffff653c660 type <integer_type 0x7ffff652d1f8
bitsizetype> constant 512>
    unit-size <integer_cst 0x7ffff661f180 type <integer_type 0x7ffff652d150
sizetype> constant 64>
    align:512 warn_if_not_align:0 symtab:0 alias-set -1 canonical-type
0x7ffff6622b28 precision:512 min <integer_cst 0x7ffff661f150 0> max
<integer_cst 0x7ffff6625000
0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff>>

So this may well be a powerpc target bug.
