Er, I meant to attach it, it is attached now. :)
It requires Boost trunk, and the timer file hpp I include is part of
the Boost.Spirit2.1 examples/test/somewhere_in_there area, but I
included it with my cpp file too so you do not need to hunt for it.
The defines at the top control what parts to compile or not, 0 to
disable compiling for that part, 1 to enable it.
My build is built with Visual Studio 8 (2005) with SP1. Compiler
options are basically defaults, except getting rid of the secure crt
crap that Microsoft screwed up (enabling that crap slows down Spirit
parsers on my system, a *lot*). The exe I built is in the 7zip file
attached. As stated, I have heard that Visual Studio handles template
stuff like Spirit better then GCC, so I am very curious how GCC's
timings on this file would be. There are still more changes to make
that I intend to make, but I really want the original code in a way
that I can use it.
To be honest, I had to change the core::to_number lines (commented
out) to boost::lexical_cast (right below the commented version), so
the xpressive version could be slightly faster if I actually had the
implementation of core::to_number available, and core::to_number was
well made. The xpressive code also throws a nice 100 line long
warning in my build log, all just about a conversion warning from
double to int_64, no clue how to fix that, I do not know xpressive, so
I would gladly like it if someone could get rid of that nasty warning
in my nice clean buildlog. In my compiler, my Spirit2.1 grammar
builds perfectly clean, I would like it if xpressive was the same way.
I honestly do not know *why* the Spirit version is so much faster then
the xpressive version, the spirit-quick version (the non-threadsafe) I
whipped up in about 2 minutes. The threadsafe version took about 5
minutes, the grammar/threadsafe/reusable version took about 10
minutes, and I know a lot more work was put into the xpressive
version, especially with the auto macros added and all such as well.
I would love it if someone could find out way. If someone else with
MSVC, and someone with GCC and perhaps other things could build it and
display the results that it prints out too, I would be much
appreciative. I do have a linux computer here, but, to be honest, no
clue what to pass to gcc to build something, the command line switches
I pass to MSVC's version is rather monstrous, so trying to convert
that to GCC's seems nightmarish from my point of view.

And I have not tested the hand-coded parser as I cannot get it to
compile. If you can get me a code-complete standalone version of it,
I would be very happy. :)
Either way, Windows users, could you please run the attached exe (that
is in the 7zip file) and paste the results it tells you in an email to
this thread, along with your windows version and basic hardware?
Before I attach this, I am going to run the release exe through a
profiler right quick.
