Run through GNU indent using indent profile. Manually fix some changes
(particularly functions such as BuildBC_Insn() which have large numbers
of arguments).

New modular directory structure: parsers, preprocs, and outfmts.
Moved token.l.in, bison.y.in, and gen_instr.pl to parsers/nasm/.
New parser, preproc, and outfmt structures. None are complete; outfmt
needs the most work.
The raw preprocessor added (for no preprocessing).
Currently the default for the nasm parser is to use the raw preproc; this
should be changed to nasm_preproc once the nasm preprocessor is finished.
A dbg output format is also new; because outfmt isn't done yet, there's not
much implementation.
What structures still need creating: listfmt, debugfmt.

Add lexing, parsing, and internal format for strings and character constants.
Completely handle data declarations (db/dw/etc) and reserve space declarations
(resb/resw/etc).

At least in NASM syntax, there is no differentation between labels and data
declarations, so delete SYM_DATA. We may add it back in someday if we add
another syntax.

Repo-copied include files to src to make automake/autoconf build structure
work properly. Changed Makefile.am, src/Makefile.am, and configure.in to
match directory changes.

First attempt at supporting relative jump instructions. A few hacks, but
seems to work well.
A few other minor fixes/changes as well (noticed when coding).

Long hairy integration of expression handling into the grammar.
Added printing, getvalue functionality to expr.[ch]
Changed immval to house an expr* instead of an unsigned long.
gen_instr.pl needs to be updated for ONE cases to fix pointer compares.
bison s/r conflicts still need to be handled.

Change groupdate into an array, and make everything 0-based in the output
code. Bit of a kludge required in gen_instr.pl to slide the $0.\d down by
one (is there a better way to do it?).
Michael Urman [Thu, 5 Jul 2001 04:53:13 +0000 (04:53 -0000)]
Added support for spitting out multiple warnings and errors.
And consequently decided that i'm probably not validating half the
fields correctly. Maybe peter will fix that. Hint hint.

Completely reorder instructions to match that in GNU binutils
/include/opcode/i386.h, used for the GAS assembler.
This also helped find some missing instructions and CPU field errors, not
all of which have been added/corrected yet.

Use %1 and %2 instead of %s and %d for "duplicate definition" error message
(allows message to be arbitarily changed, including reversing order of %1 and
%2 without having to change every location it's called from).

Add instruction grouping to decrease size of generated yacc code.
gen_instr.pl still needs to actually implement this, so this currently breaks
the build.

Use autoconf to determine when to include our implementation of strdup, so
remove util.c and create strdup.c. Make util.h, strdup.c, and several source

Added handling of labels including:
better symbol table functions
calling them from yacc rather than lex
a new warning for .label before normal_label
locallabel_base now a symrec* instead of a strdup'd string.
Still needs some more error checking (to not allow multiple copies of
the same label, etc.)
Also includes move to y_strdup for bison.y.in (ANSI compatibility)

Reorganize (yet again) effective address, immediate value, and instruction
structures.
Add more interface functions to isolate structure internals and make it
easier to add warnings (such as for multiple overrides/prefixes).
