Switch from custom assert() to libc assert() in mach/proto/as.
Continue to disable asserts if DEBUG == 0.
This change found a problem in the build system; comm2.y was missing
depedencies on comm0.h and comm1.h. Add the missing dependencies to
the cppfile rule. Allow the dependencies by modifying cppfile in
first/build.lua to act like cfile if t.dir is false.
Now that comm2.y gets rebuilt, I must fix the wrong prototype of
yyparse() in comm1.h.
I got unlucky as induo() in comm5.c was reading beyond the end of the
array. It found an operator "= " ('=' then space) in the garbage, so
it returned a garbage token number, and "VAR = 123" became a syntax
error. Unbreak induo() by terminating the array.
Change "register i;" to "int i;" to so clang stops warning about
implicit int. Use function prototypes so clang stops warning about
implicitly declared functions.
I need this so I can add more %token lines to mach/powerpc/as/mach2.c
The assembler's tempfile encoded each token in a byte. This only
worked with tokens 0 to 127 and 256 and 383. If a token 384 or higher
existed, the assembler stopped working. I need tokens 384 and higher.
I change the token encoding to a 2-byte little-endian integer. I also
change a byte in the string encoding.
See issue #1 (https://github.com/davidgiven/ack/issues/1). The file
mach/proto/as/comm2.y goes through cpp twice. The _include macro,
defined in comm2.y and used in comm0.h, delays the inclusion of system
header files. The inclusion of <stdint.h> wasn't delayed. This
caused multiple inclusions of <sys/_types.h> in FreeBSD and
<machine/_types.h> in OpenBSD.
Use _include to delay <stdint.h>. Also use _include for "arch.h" and
"out.h", because h/out.h includes <stdint.h> and h/arch.h might
include it in the future.
Sort the system includes in comm0.h by moving them up to be with
<stdint.h>. Must include <stdint.h> before "mach0.c", because
mach/powerpc/as/mach0.c needs it. Must include "mach0.c" before
checking ASLD.
In my OpenBSD/amd64 system, the code becomes
if (0)
outname.on_valu &= ~(((0xFFFFFFFF)<<32)<<32);
The 0xFFFFFFFF is a 32-bit int, so the left shift by 32 is out of
range and causes the gcc warning.
The intent might be to clear any sign-extended bits, if the assignment
outname.on_valu = valu did sign extension. Old C had no unsigned
long, so .on_valu would have been long. The code is obsolete because
h/out.h now declares .on_valu as uint32_t.
the number of types of relocation possible in the object file. (Now,
hopefully, working.)
Also change the object serialiser/deserialiser to never try to read or
write raw structures; it's way safer this way and we don't need the
performance boost any more.

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.
