            Bug ID: 59142
           Summary: internal compiler error while compiling OpenCV 2.4.7
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: joao.m.santos.silva at gmail dot com

This is on an ARM platform with Ubuntu/Linaro 13.10.

While building OpenCV 2.4.7 with:

  cmake -D CMAKE_BUILD_TYPE=RELEASE -D
CMAKE_INSTALL_PREFIX=/home/jm/fidelio/3rd-party/opencv/2.4.7/linaro ..
  make

I got:

--- Comment #3 from Cong Hou <congh at google dot com> ---
How do you generate the final operations in vectorized code?

I just submitted a patch on this issue. The patch supports non-isomorphic
operations with the restriction that all operations on even/odd elements still
be isomorphic. Please give me the comment on this patch.

Thank you!

Works in 4.7.0.  I notice you are using Ubuntu's compiler you really should
have reported it there.

OK, thanks, I will report in Ubuntu's.

The compiler says:

$ gcc --version
gcc (Ubuntu/Linaro 4.8.1-10ubuntu8) 4.8.1

Should I report also in Linaro's? I'm not yet familiarized with Linaro's role
in gcc.

Iain - could you please explain this a little more?  Which are the stacked
structs that aren't aligned, and where do they come from?

Thanks!

unrelated to Linaro changes, fails on the 4.8 branch and trunk with -mthumb and

Comparing reduced.cpp.153r.cse1 in r172837 and the previous commit.

--- reduced.cpp.153r.cse1 from gcc trunk r172835 [works]

        ]) reference/reduced.cpp:6 373 {*stm2_ia}
     (nil))


--- reduced.cpp.153r.cse1 from gcc trunk r172837 [has ICE]

        ]) reference/reduced.cpp:6 373 {*stm2_ia}
     (nil))


This gets re-written later:
-- reduced.cpp.190r.ira from gcc trunk r172837
(insn 24 29 28 2 (parallel [
            (set (mem/s:SI (reg/f:SI 4 r4 [141]) [5 MEM[(struct A *)0B]+0 S4
A32
])
                (reg:SI 0 r0))
            (set (mem/s:SI (plus:SI (reg/f:SI 4 r4 [141])
                        (const_int 4 [0x4])) [5 MEM[(struct A *)0B]+4 S4 A32])
                (plus:SI (reg/f:SI 13 sp)       <---\__ was aftp

        ]) reference/reduced.cpp:6 373 {*stm2_ia}
     (nil))


The (plus:SI (reg/f:SI 13 sp) (const_int 1048 [0x418])) is the invalid operand
which causes the ICE during final.
