--- Comment #13 from anlauf at gcc dot gnu.org ---
I've come back to this PR again and spent a while trying to further narrow
things down and to find the gcc options that make the code compile or fail.
Minimal reproducer:
complex function f2 (a)
implicit none
integer a
logical e2
entry e2 (a)
if (a > 0) then
e2 = .true.
else
f2 = 45
endif
end
Basic command line: "gfortran -fdefault-integer-8", plus:
these all lead to an ICE:
! -O1
! -O1 -fno-tree-pre
! -O2 -fno-tree-pre
but no ICE with:
! -O2
! -O1 -ftree-pre
! -O2 -ftree-pre
! -O1 -fno-tree-sra
! -O2 -fno-tree-sra
! -O1 -fno-tree-sra -fno-tree-pre
! -O2 -fno-tree-sra -fno-tree-pre
So is this now a frontend bug - what could it be? - or a middle-end issue?
