It is extremely desirable to allow the user fine-grained control of
warnings, but this has been complicated by the fact that a warning
class has had to be defined in no less than three places (error.h,
error.c, nasmdoc.src) before it can be used in source code. Instead,
use a script to define these via magic comments at the point of use.
This hopefully will encourage creating new classes as needed.

It is possible on memory exhaustion that nasm_fatal() might cause
another allocation error, thus calling nasm_alloc_failed() again. If
we find us in nasm_alloc_failed() for a second time, try to get a
message out and then call abort().

Add a version of (v)asprintf(), which allocates a string on the
heap. Unlike the standard version of (v)asprintf(), we return the
pointer; if one wants the length of the string then one can simply use
the %n pattern.

of strlist, with the find and linearize capabilities. Merge these two

Apparently it isn't just NMAKE which is sensitive to the ordering of
.SUFFIXES, it apparently applies just as well to Unix make.

1. The mkdep.pl program didn't handle excluded dependencies correctly,
causing it to error out due to config/config.h not existing.
2. NMAKE is sensitive to the order suffixes appear in .SUFFIXES,
causing it to try to use the builtin rule .c.exe instead of
.c.obj -> .obj.exe.
3. NMAKE doesn't handle the && operator between commands.
4. The !ifdef jungle around dependency generation was wrong.

Make further autoconf rule improvements and update the required

This is a fix for a4f6ca5a33
- We should not use sole CPPFLAGS when compiling,
but rather merge it into ALL_CFLAGS
- nasm.spec.in should use DESTDIR since
INSTALLROOT now renamed to it
Signed-off-by: Cyrill Gorcunov <gorcunov@gmail.com>
* CPPFLAGS is a user variable and should be respected
when compiling .c files. Think of -D_FORTIFY_SOURCE=2.
* Pass ALL_CFLAGS when linking too. This is recommended
for certain edge cases (-flto)
* Use DESTDIR instead of INSTALLROOT for staging dir
Every other build system (Automake, CMake, Meson) uses
DESTDIR. This integrates better into distro and other
build systems that have standard hooks for DESTDIR.
* $(MAKE) -C <dir> is better than cd'ing into a <dir>
* Use Autoconf's ${docdir} and ${htmldir} for installing
the documentation. This makes handling documentation
easier and respects user choice.

Several output formats use "string tables", which is a collection of
null-terminated (C) strings which are referenced by a byte offset into
the string table. A single string can be referenced an arbitrary
number of times.
As this is quite simple to implement with a hash table, we do exactly
that.

The standard syntax for a phony target in Make is:
target: <dependencies>
.PHONY: target
... however, Watcom WMAKE seems to use
target: <dependencies> .SYMBOLIC
and furthermore, seems to *require* it. Therefore, remove the
"perlreq" target from the automatically distributed region and move it
into the specific region; it should not need to change anyway since
the PERLREQ list itself is still synced.
If it was only a matter of the .SYMBOLIC versus .PHONY token it would
be easy enough to change that in syncfiles.pl, but this syntax change
is big enough that it doesn't make enough sense to worry about.

Add a generic facility for generating perfect string hashes, where all
that is needed is an enum and a string table. The existing mechanism
using a custom Perl script wrapped around a module continues to be
available for any use case where this particular approach isn't
sophisticated enough.
Much of this patch comes from renaming "enum directives" to "enum
directive" as a result of the string hash generator expecting a set of
uniform naming conventions.

There is no fundamental reason for all objects that don't contain a
main() function to not be part of libnasm.a; this allows the linker to
do its job optimally, especially in the presence of debugging code
which may not be needed under normal conditions.
If we do end up with function name conflicts the library might have to
be split, but it would be better to simply avoid that case.
