Patch which fixes the reduced testcase
Sorry about the name of the patch but reload is the worst code I have ever
read.

This is the same problem as listed in PR 20606 which is not exposed by -freorder-blocks-and-partition
at all. I am looking into this further.

the following configure options:
Configured with: ../configure --target=powerpc64-linux-gnu --with-cpu=default32

The jump:
(jump_insn:HI 2539 2830 2305 120 (set (pc)
(reg:SI 66 ctr)) 482 {*indirect_jumpsi} (insn_list:REG_DEP_TRUE 2537 (insn_list:REG_DEP_TRUE
2538 (insn_list:REG_DEP_TRUE 1498 (nil))))
(insn_list:REG_LABEL 1504 (expr_list:REG_CROSSING_JUMP (nil)
(nil))))
And the backtrace:
#0 fancy_abort (file=0x92cb54 "../../gcc/cfgbuild.c", line=350, function=0x8e5374 "make_edges") at
../../gcc/diagnostic.c:590
#1 0x007db014 in make_edges (min=0x2dd87e8, max=0x2df70b0, update_p=1) at ../../gcc/
cfgbuild.c:350
#2 0x007dc378 in find_many_sub_basic_blocks (blocks=0x1b6d240) at ../../gcc/cfgbuild.c:763
#3 0x0059a7f8 in split_all_insns (upd_life=0) at ../../gcc/recog.c:2795
#4 0x003898ec in rest_of_handle_flow2 () at ../../gcc/flow.c:4624
#5 0x0069f964 in execute_one_pass (pass=0x9fdef4) at ../../gcc/passes.c:809
This makes me feel better. Plus this is a bug really related to/exposed by -freorder-blocks-and-
partition, we are changing an direct into an indirect one but make_edges is not thinking it should get
an indirect to a known label here or at least as far as I can tell.
Looking more into it.

Actually the jump_insn and the backtrace does not make sense because it should have triggered the
computed_jump_p part in make_edge.
Can you add a fflush(dump_file); right after the print_rtl_single. Also can you attach all of the dumps
for -fdump-tree-all-all because the backtrace does not make sense between that the jump_insn having
registers allocated already.

Dump from -fdump-rtl-expand-all
Output from -fdump-rtl-expand-all attached as requested.
Note that the jump instruction I posted was obtained by placing the following
call directly before the failing gcc_assert.
print_rtl_single (dump_file, insn);
gcc_assert (JUMP_LABEL (insn)); /* failing assert at cfgbuild.c line 350
*/

Huh, this should be an indirect call and not a jump.
Can you attach the dumps from -fdump-rtl-expand-all?
