*much* less overhead.
XXX: current implementation of HAMT is *not* portable due to pointer alignment
restrictions (it uses the LSB of a pointer to store a flag). Need to write a
portable (if not so space-efficient) equivalent.

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.

data pointers to symrec for extern/common/etc. Also fixed parsing of direxpr;
it didn't allow exprs with ID's before.

nicer output by only outputting the "reported only once" informational message
once, for the first (line-wise) error.
Note: this isn't foolproof, as different files have different line countings...
need a monotonically increasing "line" counter to fix this. This is a problem
in more areas than just here, though.

objfmt interface changed a lot due to this.
- New variables cur_objfmt and cur_parser that define what objfmt/parser are
active. They're set in main() by searching through the list of objfmts and
parsers. This necessitated libyasm.a to be listed twice in LDADD.

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.

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.
svn path=/trunk/yasm/; revision=278
- 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).

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.

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.
svn path=/trunk/yasm/; revision=252
Interface changed slightly (only affects symrec.c right now). Tests committed
to check a single case (pi) with all three size conversion functions.
Still need to write to/from ASCII string functions (the hard part).
svn path=/trunk/yasm/; revision=247
properly (bug #8). Framework added for portable floating point support (bug
#7). Lots of functions still not finished in this commit.
svn path=/trunk/yasm/; revision=229
Cleaned up function naming too.
Removed locallabel_base from global.h, moving it into the parser-specific code.
Made sym_table private to symrec.c.
svn path=/trunk/yasm/; revision=220
(allows message to be arbitarily changed, including reversing order of %1 and
%2 without having to change every location it's called from).
svn path=/trunk/yasm/; revision=88
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)
