Subject: Re: [PHP-DEV] [PATCH] arithmetic speedup
From: pierre.php@gmail.com (Pierre Joye)

hi Dmitry,

Nice improvements, thanks :)

Any reason not to have done the changes for windows as well?

What's about putting the asm code in external file so it can used by
more compilers? (some has issues with inline asm, like VC in x64 mode,
other may have as well afair).

Cheers,
