I have partly written patch, but would like to understand whether ordering
matters or not.
Is the following all valid f77/f90/f95?
subroutine foo
character*8 c
character*1 d, f
dimension d(2), f(2)
character*4 e
equivalence (c(1:1), d(1)), (c(3:5), e(2:4)), (c(6:6), f(2))
c='abcdefgh'
if (c.ne.'abcdefgh'.or.d(1).ne.'a'.or.d(2).ne.'b') call abort
if (e.ne.'bcde'.or.f(1).ne.'e'.or.f(2).ne.'f') call abort
end subroutine foo
subroutine bar
equivalence (c(1:1), d(1)), (c(3:5), e(2:4)), (c(6:6), f(2))
character*8 c
character*1 d, f
dimension d(2), f(2)
character*4 e
c='abcdefgh'
if (c.ne.'abcdefgh'.or.d(1).ne.'a'.or.d(2).ne.'b') call abort
if (e.ne.'bcde'.or.f(1).ne.'e'.or.f(2).ne.'f') call abort
end subroutine bar
subroutine baz
character*8 c
character*1 d, f
character*4 e
equivalence (c(1:1), d(1)), (c(3:5), e(2:4)), (c(6:6), f(2))
dimension d(2), f(2)
c='abcdefgh'
if (c.ne.'abcdefgh'.or.d(1).ne.'a'.or.d(2).ne.'b') call abort
if (e.ne.'bcde'.or.f(1).ne.'e'.or.f(2).ne.'f') call abort
end subroutine baz
subroutine another
dimension d(2), f(2)
equivalence (c(1:1), d(1)), (c(3:5), e(2:4)), (c(6:6), f(2))
character*8 c
character*1 d, f
character*4 e
c='abcdefgh'
if (c.ne.'abcdefgh'.or.d(1).ne.'a'.or.d(2).ne.'b') call abort
if (e.ne.'bcde'.or.f(1).ne.'e'.or.f(2).ne.'f') call abort
end subroutine another
program main
call foo
call bar
call baz
call another
end program main
Can equivalence contain sym%name or is that forbidden?
