Unfortunately, it doesn't:

* You missed one issue I had reported before:

FAIL: gcc.target/x86_64/abi/ms-sysv/ms-sysv.c  -O2 "-DGEN_ARGS=-p0\ -t64" (test
for excess errors)
Excess errors:
/var/gcc/regression/trunk/12-gcc/build/gcc/testsuite/gcc/ms-sysv/ms-sysv-generated.h:30:1:
error: bp cannot be used in asm here
Assembler: 
        "/var/tmp//ccVdks6a.s", line 43 : Symbol "regs_to_mem" already has a
size

  Fixed like this:

* Also as I'd reported before, with the fix above, I still get a couple
  of FAILures:

  At least some of the tests PASS now :-)

Besides, can you *pretty please* concentrate on the issue at hand in
this PR, i.e. the failing tests on i?86 -m64?  Most/all of your
cleanups, nice as they may be on their own, have nothing to do with the
PR and just distract from the main issue.

Thanks.
