------- Additional Comments From janis187 at us dot ibm dot com 2003-07-24 23:31 -------
The regression in PR 11640 was introduced or exposed by this patch:
--- gcc/gcc/ChangeLog ---
2003-03-23 Richard Henderson <rth@redhat.com>
* cfgcleanup.c (try_optimize_cfg): Allow merging of tablejumps
before flow2.
* cfgrtl.c (try_redirect_by_replacing_jump): Similarly.
The regression hunt took place on i686-pc-linux-gnu with a cross cc1
for powerpc64-linux, using the test case in comment #2 with "-g -O2".

------- Additional Comments From zlomek at gcc dot gnu dot org 2003-09-09 12:35 -------
The bug occurs on 3.3 branch with checking enabled too.
I was analyzing the bug, the problem is that when try_redirect_by_replacing_jump
changes the tablejump to a simple jump the label is not completelly deleted
because it is still used in code. When merging blocks the return is copied to
place where the tablejump was, the barrier is not directly after the (return)
jump and it causes the ICE. I hope this description helps to fix the bug (by
someone else).
(insn 110 69 49 2 (set (reg:DI 66 ctr [136])
(reg:DI 0 r0)) 326 {*movdi_internal64} (insn_list 69 (nil))
(expr_list:REG_DEAD (reg:DI 0 r0)
(nil)))
(note 49 110 53 2 ("/suse/zlomekj/a.c") 18)
(insn 53 49 112 2 /suse/zlomekj/a.c:18 (set (reg:DI 3 r3 [orig:118 <result> ] [118])
(const_int 8 [0x8])) 326 {*movdi_internal64} (nil)
(nil))
(jump_insn 112 53 132 2 (return) -1 (nil)
(nil))
(note/s 71 132 73 "" NOTE_INSN_DELETED_LABEL 10)
(barrier 73 71 17)
(note 17 73 25 13 ("/suse/zlomekj/a.c") 10)
Although the following patch fixes the testcase it does NOT bootstrap.

It causes the barrier to be emmitted but leaves the other one there:
