Adds a new Makefile variable DEBUG that controls whether a symbol file (.PDB)
is created for the executables, e. g., nmake -f Mkfiles\msvc.mak DEBUG=1

45a22d9a61 changes the arguments of insns.pl
and adds a new autogenerated header iflaggen.h. Update the nmake Makefile
accordingly.

For OS2 target the -bt option should be set accordingly.

Apparently some people still care about compiling native on MS-DOS,
and we don't have a significant number of files which need adjustment.

Add ilog2_{32,64}() and alignlog2_{32,64}() ... the latter is intended
for alignment statements and return -1 for non-power-of-2 other than 0
(which returns 0).

Merge elfcommon.h, elf32.h, elf64.h into
single elf.h -- we do support both elf32
and elf64 anyway. Let put them into common
place.

Add strlcpy() function and implementation, and use configure to detect
if strlcpy() is natively available on the system.

Hash all directives, even the ones that are backend-specific,
and instead pass the backend an already-parsed directive number.
Furthermore, unify null functions across various backends.

Move backend-specific code into the output/ directory, and make the
null debugging backend a separate file (it certainly isn't needed for
ndisasm...)

The dependency machinery relies on properly rooted includes, so give
it to them... the path syntax munging machinery in the dependency
script handles it from a Makefile syntax perspective, and then we can
hope that C compilers are smart enough to deal with forward-slash
paths even when that is not the native syntax.

Linear searches are evil, so use an llrbtree to search for symbols by
offset. This doesn't change the preexisting behaviour that we only
look for global symbols.

Move all the version strings to a single compilation unit, ver.c; this
does not include the version macros, which are fed into macros.c.

Drop the data pointer, and instead assume the struct rbtree will be
embedded in a bigger data structure (to be extracted via
container_of()).

Implement library functions for "left-leaning red-black trees" with
uint64_t keys. This is meant for looking up symbols by address in the
backends that need to do so, e.g. ELF.
A good question is if there is a better way to do this, that recovers
the original symbol, but that's a future issue.

Add a common file, outlib.c, for output formats. Add the function
realsize() instead of open-coded variants in almost every backend.

Add a builtin equivalent to the %include directive called %use.
%use includes a standard macro file compiled into the binary; these
come from the macros/ directory in the source code.
The idea here is to be able to provide optional macro packages with
the distribution, without adding complex host filesystem dependencies.
"make alldeps" doesn't really like it when included files end in *.c.
Instead of renaming insnsb.c to insnsb.h, make it an actual
compilation unit, since there really isn't any reason for it not to
be.
Generate a byte array instead of using C compiler strings for the byte
codes. This has a few advantages:
- No need to special-case zero due to broken C compilers.
- Only insns.pl only ever reads the string, so we can invent our own
syntax.
- Compaction.
- We can give it the proper, unsigned type.
When using temporaries in macros, given them a unique prefix to avoid
namespace collisions when using one macro inside another.
Move the WSAA*() macros from outelf32/outelf64 to a separate header
file.
OpenWatcom needs different strings for compile and link target, so
using -bcl which uses the same string for both is just plain wrong.
This fixes that bit, but running nasm on test/floatx.asm (at least as
a DOS or a Win32 binary) crashes with a NULL pointer reference inside
the C library free() function.
To deal with fools^Wpeople trying to keep really old systems alive,
create a proper framework for substitution functions, and make it
possible to deal with the lack of snprintf/vsnprintf in particular.
Add a Makefile for OpenWatcom using WMAKE. This is a horrible version
of Make, but since it's bundled with OpenWatcom it is probably better
to stick to it. It has the nice property that it can produce DOS,
Win32 or OS/2 binaries.
This Makefile currently assumes that it is hosted on a system where
pathname separators are backslashes. For cross-compiling using
OpenWatcom on a Linux system it is probably better to write a separate
Makefile using GNU make to invoke Watcom.
Add special operators to allow the use of floating-point constants in
contexts other than DW/DD/DQ/DT/DO.
As part of this checkin, make MAX_KEYWORD generated by tokhash.pl,
since it knows what all the keywords are so it can tell which one is
the longest.
Sort the dependency lists generated by "mkdep.pl", to make sure that
re-running "make alldeps" doesn't change anything unless there has
been real dependency changes. The previous version could produce
different output between runs and across platforms.
Use the new hash table function library to store labels. When
compiling on my 64-bit system, it reduces the assembly time for the
output of test/perf/label.pl from 73 to 7 seconds.
We have a lot of enumerations; by declaring fields as such, we make it
easier when debugging, since the debugger can display the enumerations
in cleartext. However, make sure exceptional values (like -1) are
included in the enumeration, since the compiler otherwise may not
include it in the valid range of the enumeration.
Finish the perfect hash tokenizer, and actually enable it.
Move stdscan() et al to a separate file, since it's not needed in any
of the clients of nasmlib other than nasm itself.
Run make alldeps.
a) Automatically generate dependencies for all Makefiles;
b) Move register definitions to a separate .dat file;
c) Add support for "unimplemented but there in theory" registers.
