Add an x32 ELF (32-bit code with the CPU in 64-bit mode) backend.
|
|
For OS2 target the -bt option should be set accordingly.

Change the OpenWatcom WMAKE Makefile to use the facilities available
in WMAKE to support cross-compilation properly.
See BR 3079573.

Classic DOS doesn't have del /f, and we don't really need it.

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.

We can use a perfect hash to decode directives as well.

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.

Be consistent about the naming of the version Makefile fragment. We
use .mak elsewhere for Makefiles, so use that.
|
|
|
|
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.

mkdep.pl already used #-- ... --# (two dashes) whereas syncfiles.pl
was using #--- ... ---# (three dashes). Change syncfiles.pl to match
mkdep.pl.
|
|
Correctly handle the null path separator (meaning remove the directory
portion entirely.)
|
|
Add a script to automagically synchronize the list of object files
between the various Makefiles.
|
|
Sync the file list in Mkfiles/*.mak
|
|
Implement __utf16__() and __utf32__() for the DB family of
pseudo-instructions. Not yet implemented for evaluation context.

The RAA code doesn't have to be in nasmlib; it is only used by nasm
itself, and is better handled in a separate module.
|
|
Move all the SAA code out of nasmlib; it's not used by anything than
nasm itself. Cleaning out the kitchen sink known as nasmlib is a good
thing, too.
|
|
Change the WSAA macros into functions; reducing the icache footprint.
|
|
|
|
Add quote.c to all the auxiliary Makefiles, and run "make alldeps".
|
|
|
|
wmake uses & for continuation, since \ is used for pathname
separators.
|
|
The Makefile uses VPATH and stripped directory names for files, so
generate the dependencies accordingly.
|
|
Don't #include .c files, even if they are auto-generated; instead
compile them as separate compilation units and let the linker do its
job.
|
|
"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.

Apparently -6 compiles are defined to run on anything 386 or newer,
and just use different instruction timings.

Add Makefile for Netware, using the GNU toolchain.

Add a Makefile variable, DEBUG, which can be used to set debug options
(-d2, -DLOGALLOC, etc.)
