If a .c file included "types.h" before "mach.h", then it missed the
declaration of mach_option(). Fix by adding "xmach.h".
Fix mach/powerpc/ncg/mach.h and mach/vc4/ncg/mach.h to use the correct
type in their printf() format strings.
Most machines had undefined valu_t and redefined it to a different
type. Edit mach/*/as/mach0.c to remove such redefinitions, so the
next change to valu_t will affect all machines.
Edit mach/proto/as/comm0.h to change valu_t to int64_t, and add
uvalu_t and uint64_t.
Remove int64_t y_valu8 from the yacc %union, now that valu_t y_valu
can hold 64 bits. Replace y_valu8 with y_valu. The .data8 pseudo
becomes less special; it now accepts absolute expressions.
This change simplifies the assembler and seems to have no effect on
the assembled output. Among the files in share/ack/examples, the only
changes are in hilo_bas.* and startrek_c.linuxppc, but those files
seem to change whenever I rebuild them.
This turns EM `con 5000000000I8` into assembly `.data8 5000000000` for
machines i386, i80, i86, m68020, powerpc, vc4. These are the only ncg
machines in our build.
i80 and i86 get con_mult(sz) for sz == 4 and sz == 8. The other
machines only get sz == 8, because they have 4-byte words, and ncg
only calls con_mult(sz) when sz is greater than the word size. The
tab "\t" after .data4 or .data8 is like the tabs in the con_*() macros
of mach/*/ncg/mach.h.
i86 now uses .data4, like i80. Also, i86 and i386 now use the numeric
string without converting it to an integer and back to a string.
EM instructions _rol_ and _ror_ do rotate an integer left or right.
Our compilers and optimizers never emit _rol_ nor _ror_, but I might
want to use them in the future.
Add _rol_ and _ror_ to powerpc. Fix `rol 4` and `ror 4` in both i80
and i86, where the rules for `rol 4` and `ror 4` seem to have never
been tested until now.
gcc gave an error because the `char *` parameter doesn't match the
`const char *` in the prototype of regsave(). clang didn't give an
error. I added the prototype in commit 5301cce.
This breaks all machines because the declared return type void
disagrees with the implicit return type int (when I compile mach.c
with clang). Unbreak i386, i80, i86, m68020, powerpc, vc4 by adding
the return types to mach.c. We don't build any other machines; they
are broken since commit a46ee91 (May 19, 2013) declared void prolog()
and commit fd91851 (Nov 10, 2016) declared void mes(), with both
declarations in mach/proto/ncg/fillem.c.
Also fix mach/vc4/ncg/mach.c where type full is long, so fprintf()
must use "%ld" not "%d" to print full nlocals.
directories --- wrangling descr files was too hard. C programs can be built
for cpm, pc86, linux386, linux68k!

These files "magically reappeared" after the conversion from CVS to
Mercurial. The old CVS repository deleted these files but did not
record *when* it deleted these files. The conversion resurrected these
files because they have no history of deletion. These files were
probably deleted before year 1995. The CVS repository begins to record
deletions around 1995.
These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted. There is no way to fix
this, because the CVS repository provides no dates of deletion.

how platform libraries are built. The ARCH pm variable has now been
renamed PLATFORM (which is more accurate) and a different ARCH
variable added, which represents the CPU family rather than the
hardware platform.
