This came up because I was looking at ld/tmpdir/addpcis.o and noticed
the odd addends on REL16DX_HA. They ought to both be -4. The error
crept in due REL16DX_HA howto being pc-relative (as indeed it should
be), and code at gas/write.c:1001 after this comment
/* Make it pc-relative. If the back-end code has not
selected a pc-relative reloc, cancel the adjustment
we do later on all pc-relative relocs. */
*not* cancelling the pc-relative adjustment. So I've made a dummy
non-relative split reloc so that the generic code handles this, rather
than attempting to add hacks later in md_apply_fix which would not be
very robust. Having the new internal reloc also makes it easy to
support
addpcis rx,sym@ha
as an equivalent to
addpcis rx,(sym-0f)@ha
0:
The patch also fixes overflow checking, which must test whether the
addi will overflow too since @l relocs don't have any overflow check.
Lastly, since I was poking at md_apply_fix, I arranged to have the
generic gas/write.c code emit errors for subtraction expressions where
we lack reloc support.

- allowing true forward references (which will always assume the referenced
symbols have at the point of use) through the new .eqv pseudo-op and the
new == operator
- disallowing changing .equiv-generated equates (so that the protection this
provides is both forward and backward)
- snapshotting equates when their value gets changed so that previous uses
don't get affected by the new value.
- allowing expressions in places where absolute expressions (or register
names) are needed which were not completely resolvable at the point of
their definition but which are fully resolvable at the point of use
In addition it fixes PR/288.
