* trans-common.c (get_init_field): New function.
(create_common): Call get_init_field for overlapping
initializers in equivalence blocks.
* resolve.c (resolve_equivalence_derived, resolve_equivalence):
Remove constraints on initializers in equivalence blocks.
* target-memory.c (expr_to_char, gfc_merge_initializers):
New functions.
(encode_derived): Add the bit offset to the byte offset to get
the total offset to the field.
* target-memory.h : Add prototype for gfc_merge_initializers.

Just to let you all know; I have had a patch ready for this and PR30875 for
somewhile.  This was awaiting the commit of Brook's simplify_transfer patch and
all the machinery in target-memory.c.  Well, during the wait it suffered a bit
of x86_ia64 specific bit-rot, whose cause I just do not see right now. Ia m
working on it, though:)

I'm changing the name of this bug to make it a lot easier to find, now that we
know what the actual problem is.

Also, PR #31672 contains an excellent testcase for this, which I'll quote here:

--
function d1mach(i)
implicit none
double precision d1mach,dmach(5)
integer i,large(4),small(4)
equivalence ( dmach(1), small(1) )
equivalence ( dmach(2), large(1) )
data small(1),small(2) / 0,   1048576/
data large(1),large(2) /-1,2146435071/
d1mach = 0.0d0
end function d1mach

The release manager is the only one who is able to change the priority. 
Changing the Priority back to P5 based on this is a fortran bug so not blocking
the release.
