Fix for PR28237 and the last bit of PR2320.
I have not had time to do a full regtest; just gfortran.dg/print*, which
includes the following testcase (print_fmt_5.f90):
Paul
! { dg-do compile }
! print_fmt_5.f90
! Test of fix for PR28237 and the last bit of PR2320. See
! below for the description of the problem.
!
program r
character(12) :: for = '(i5)', left = '(i', right = ')'
integer :: i, j
integer :: h(4) &
= (/1h(, 1hi, 1h5, 1h)/)! { dg-warning "HOLLERITH|Hollerith" }
namelist /mynml/ i
i = fact ()
!
! All these are "legal" things to do; note however the warnings
! for extensions or obsolete features!
!
print *, fact()
print 100, fact()
print '(i5)', fact()
print mynml ! { dg-warning "is an extension" }
do i = 1, 5
print trim(left)//char(iachar('0') + i)//trim(right), i
end do
assign 100 to i ! { dg-warning "ASSIGN statement" }
print i, fact() ! { dg-warning "ASSIGNED variable" }
print h, fact () ! { dg-warning "Non-character in FORMAT" }
!
! These are not and caused a segfault in trans-io:560
!
! PR28237
print fact() ! { dg-error "not an ASSIGNED variable" }
! original PR23420
print precision(1.2_8) ! { dg-error "type default CHARACTER" }
! PR23420 points 4 and 5
print j + j ! { dg-error "not an ASSIGNED variable" }
! An extension of the above, encountered in writing the fix
write (*, fact())! { dg-error "not an ASSIGNED variable" }
100 format (i5)
contains
function fact()
integer :: fact
fact = 1
end function fact
end
