Remove gas and ld support for MIPS ECOFF

- Subject: Remove gas and ld support for MIPS ECOFF
I think the time has finally come to remove GAS and LD support for MIPS ECOFF.
In the past there was talk of removing MIPS ECOFF entirely, but the response
was that some people still need it for bootloaders and the like. However,
they said that they build the loader as an ELF file and convert it to
ECOFF at the end, which definitely seems like the best approach.
So here I'm just removing the GAS and LD support but keeping binutils.
As things stand, the ECOFF support has been bitrotting for over 10 years.
Evidence of this is in the mips.exp comment:
# LOSE: As of 2002-02-08, "beq" through "bltu" fail for target mips-ecoff.
# See http://sources.redhat.com/ml/binutils/2001-10/msg00418.html for
# more information. Not sure if the fixes there are correct; should
# branches to external labels be allowed for ECOFF?
And this is the problem. We can match whatever the mips-ecoff assembler
happens to produce for a test, but without really knowing whether it's
right or not. That just becomes a meaningless maintenance burden.
This is particularly true given:
if (!IS_ELF)
{
/* A gruesome hack which is a result of the gruesome gas
reloc handling. What's worse, for COFF (as opposed to
ECOFF), we might need yet another copy of reloc->address.
See bfd_install_relocation. */
reloc->addend += reloc->address;
}
We once had a similar hack for ELF and had to keep extending it to
cope with more and more corner cases. Although the requirements are
probably different for COFF, I still doubt that this code handles
everything correctly.
As things stand, we've had 100+ tests failing on mips-ecoff for years,
so testing on that target doesn't really serve any purpose.
This patch just removes what I see as the "core" MIPS ECOFF support.
The next two patches make the MIPS source "ELF only".
The affected targets are:
- mips*-*-ecoff* itself
- mips*-*-irix*, v4 and earlier only
- mips*-*-lnews*
- mips*-*-osf*
- mips*-*-pe*
- mips*-*-riscos*
- mips*-*-ultrix*
- mips-sony-bsd (no other mips*-*-bsd was accepted by gas)
Tested on:
mips64-elf mips64el-linux-gnu mips64-linux-gnu mips-ecoff mips-freebsd
mipsisa32-elf mipsisa32el-linux-gnu mipsisa32-linux-gnu mipsisa64el-elf
mipsisa64-elf mips-kfreebsd-gnu mips-netbsd mips-sde-elf mips-sgi-irix5
mips-sgi-irix6 mips-wrs-vxworks
Applied.
After this patch there's not really any point running the testsuite
for mips-ecoff. All that's left are a few binutils tests that fail
due to lack of assembler support.
