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

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.
