- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
by the way it's used).
The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.) The __indr_reference
change was made for consistency.

New zeropage() implementation based on code contributed by Hiroshi Horitomo
...
<horimoto@cs-aoi.cs.sist.ac.jp> in PR #3641 . I changed the code slightly.
Instead of clearing 13 registers (d1-d7,a1-a6) and zeroing 512 bytes per
loop iteration, I clear 8 registers (d1-d7,a1) and zero 256 bytes. This
reduces the size and complexity of the function.
On the '020, the simpler code is less than 1% slower. Surprisingly, it
is ~3% faster on the '040.

In my earlier patch to the m68k fmovem disassembler, I repaired the register

naming for fmovem, while breaking it for fmove. We probably never will
see normal fmove in the kernel, nevertheless it should be corrected while
somebody remembers.
Besides, the correct patch is smaller and thus easier to verify than the

- correct printing of FP data register lists if all are used (only FP0
would be mentioned)
- correct printing of FP data register lists in the case the list is reversed
(would have printed nothing)
- correct mapping of fp0-fp7 to register list bits (was reversed)

Added new macro _PROF_PROLOG which contains the code sequence needed
...
to call mcount(). This is needed because the ``link a6,#0'' insn used
trips up gcc's ANSI preprocessor (A # in a function-type macro must be
followed by a macro argument). _PROF_PROLOG is also used in the i386
asm.h.
Solaris' asm_linkage.h has a MCOUNT macro similar to _PROF_PROLOG
except it expands to different code sequences based on whether a
function is being compiled with "prof" or "gprof" instrumentation.
I also discovered that the m68k ALTENTRY is very different than the
implementation used by other NetBSD ports. Usually ALTENTRY simply
provides an alternate function entry point. The m68k version takes a
second argument and jumps inside the second function when profiling is
enabled. The m68k behavior is similar to the ENTRY2 macro found in
solaris.
Providing ENTRY2 and changing all the code that uses ALTENTRY to use
it would be a desirable change.
