Bug ID: 109733
Summary: ICE in extract_insn, at recog.cc:2791 since
r14-475-g508f082829af68
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: ubizjak at gmail dot com
Target Milestone: ---
Host: x86_64-linux-gnu
I noticed the following crash:
$ cat x.f90
use iso_c_binding
interface
subroutine ctest_cont (a, is_cont) bind (c, name="ctest")
end subroutine
subroutine ctest_ar_cont (a, is_cont) bind (c, name="ctest")
use iso_c_binding
integer(C_INT), contiguous :: a(..)
logical(C_Bool), value :: is_cont
end subroutine
end interface
integer(C_INT), target :: aa(10,5)
integer(C_INT), target :: bb(10,10)
do j = 1, 5
do i = 1, 10
end do
end do
call ftest (transpose (aa), is_cont=.true._c_bool) ! Implementation choice:
copy in; hence, contiguous
call ftest (bb(2:10:2, :), is_cont=.false._c_bool)
contains
subroutine ftest (a, is_cont)
integer(C_INT) :: a(:,:)
logical(c_bool), value, intent(in) :: is_cont
call ctest_ar_cont (a, is_cont=.true._c_bool)
end subroutine
subroutine ftest_ar (a, is_cont)
end subroutine
end program
$ gfortran x.f90 -ftree-vrp -O1 -mavx512vbmi2 -m32 -march=i686 -c
