arch. This will also simplify other objfmt expr output functions. Change
file functions to use bits instead of byte/short/long, and create both little
and big endian versions. This name change caused changes in several other
files.

/distances/ between bytecodes in a section using bc_calc_dist() functions (a
"typical" one is provided for most occasions). expr_expand_labelequ() is gone,
as its functionality is integrated into expr_simplify(). Currently these
changes break most bin objfmt output, as it doesn't know how to resolve
absolute labels yet. Also, very preliminary expr support for :, SEG, and WRT
operators has been added (part of Bug#2). Several other minor bug fixes.

intnum_new_int. Currently only just calls intnum_new_uint with a cast, but
eventually there may be a better way of handling signed numbers.

Bugzilla Bug#3. Not all instructions are parsed yet, so this is actually a
minor feature regression from the user side, but this commit lays the framework
for much easier additions of new assembler syntaxes and architectures. The
re2c tool is now used to generate the lexers, as it's much more flexibly
function-oriented than lex.
- nasm-bison.y is a repocopy+modify of nasm/bison.y.in.
- x86arch.h now includes all of x86-int.h

- Add two new bytecode types:
BC_ALIGN (not yet implemented) for performing nice alignment magic.
BC_OBJFMT_DATA for storing objfmt-generated data in more advanced objfmts.
- objfmt structure changes:
Add handling functions for BC_OBJFMT_DATA data.
Allow a number of functions to be NULL.

be allocated and filled with 0's to write it out).
Other fixes:
Specifically look for floating point values in res* and multiple exprs.
One-byte PC-relative displacement *is* legal (short jumps).

bugfixes to the bc_tobytes() family and other functions. Binary object output
is now close to complete: just a few more bugs to kill!
svn path=/trunk/yasm/; revision=528
with regards to resolve_label().
MAJOR FIXME: The tobytes() pass acts like a final optimization pass. This
causes internal errors because of length mismatches (optimized to shorter len).

will probably disappear in the near future (its functionality will be handled
directly by the object format module without the need for another pass).

"index". This fixes some problems with assumptions made by various parts of
the code that are invalidated when the line number doesn't always increase (eg.
when the NASM %line directive is used).
Speed fixes are needed to the implementation of the line_* functions in
globals.c before this is finished.

into the optimizer stage, where it belongs. Naming has changed, but most
implementations have not been brought up to date to do what they say they
do.

FILE *'s to print to somewhere other than stdout, and the formatting is
improved through the use of a global indent_level.
Changes to main() include the ability to specify an output file.

This is actually worthwhile; I found and fixed a few bugs/edge cases while
doing this.

sections of C files. Also remove IdPath from top comment in files where
RCSID() is used. Move RCSID() to immediately after util.h include.

Features:
- More complex memory expressions like [bx-(bx-di)] are now calculated through
as valid.
- Much better simplification.
Internal changes:
- More flexible n-way tree (rather than old binary-only).
- Many new functions to simplify and deal with very complex expressions.

In bytecode_print(), check for NULL ea displacement and print out modrm and
sib bytes in octal (because it's easier to read the 2/3/3 format in octal).
svn path=/trunk/yasm/; revision=277
- New intnum module to replace using just unsigned long (for >32 bit values).
Read values using BitVector instead of strtoul().
- Brought both floatnum and intnum into expr (still need to integrate calc for
floatnum).
- Add traversal function to ternary tree (for use by symrec_foreach).
- Change floatnum output interface from single/double/extended to byte size.
- Try to make floatnum/intnum interfaces very similar. Still needs work.
- Add/fix *_print functions, including interating ones for sections/bytecodes.
- Fix handling of $ and $$. Both now are properly parsed and bytecode'd.
- Print out all sections and symbol table in main() in preparation for work
on "cleanup" functionality between parser and optimizer stages (really part
of the parser stage).
