[Zlib-devel] zlib-1.2.5 DLL build

[Gilles Vollant]

I still think an asm enabled version can be useful, and compare speed with a
version compiled with Visual Studio 2010 and all optimization (including
profile guided optimization)

have we a visual studio projet (not makefile only, but a .vcproj) which is
binary compatible, and an executable which is able to test your binary DLL
(or 100% compatible) with performance indication?

Since there have not been any complaints (at least, not since my last
response), nor requests to build an asm-enabled version of the DLL,
can we go ahead and publish it?

I am still curious about the state of the gcc-asm modules. By
following this list I could tell that the VC-asm modules are
well-tested, and they seem to offer a small speed improvement, but how
about gcc-asm? Did anybody run any tests? (I'd like to do that myself,
but the time I can spend on Windows is minimal these days.)

Best regards,
Cosmin
