Add option for malloc debugging using dmalloc library (http://dmalloc.com/).
Remove unnecessary stdlib includes (because we use xmalloc instead of malloc).

*COMPLETELY* rewrite most of expression handling.
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.

Allow both signed and unsigned interpretations for get_int and check_size.
Change argument order on get_int and check_size to better match other
functions (intnum * first arg).

Add parsing of memory expressions. Currently adds a lot of duplication for
the expressions in the yacc code, but I don't see an easier way right now.
Also, no validity checking is done.
Peter Johnson [Fri, 12 Oct 2001 02:34:30 +0000 (02:34 -0000)]
Add expr_contains_float() and symrec_get_equ() functions. These are the first
of many functions like this which will be needed for advanced validity checking
in the finalization of the parser stage.
Fix yacc grammar to not use the (incorrect) expr_no_fltstr, and change memexp
to memexpr and its handling to prepare for memory expressions.

Clarify and fix some usages of valid/need flags for modrm and sib bytes.
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).

Fix LOTS of little nits. Primary changes:
- 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).

Make most data structures opaque, keeping internals truly internal and making the
overall structure much more modular.
The test files, which need access to the internals of the structures being
tested, now include the source file instead of the header file to gain access
to all internal formats and functions.

Completely revamp format and extensiveness of testing.
Currently two tests fail (the approx 1.e-38 in single and double precision).

malloc->xmalloc, strdup->xstrdup, and calloc->xcalloc. The x* family performs

Add some (optional through configure) additional warning flags. Add options
to configure to enable profiling and enable -Werror. Make changes to ensure
everything builds with all additional warnings and -Werror enabled. Most of
these changes consist of adding "const" modifiers for functions that get
constant literal strings.

Finish ASCII->internal FP conversion and clean up single/double/extended

Implement floating point size conversions (with help from BitVector).

Change error/warning framework to store a list of errors and warnings instead
of just one at a time. This is the groundwork for printing undefined symbol
messages, which can't be determined until after parsing has been completed
(and should be in the same line order with the other errors).

Used ternary search tree instead of linked list to store symbol table.

Cleaned up bytecode data structure, some effaddr functions. Made ea an

Build section linked list, and support the section directive, including
