[ros-dev] Win32k Foating Point

[James Tabor]

Hi,
I've tooled up libm from http://www.netlib.org/fdlibm/ and a hacked
floatlib.c in lib/3rdparty. With -msoft-float added in win32k.rbuild,
it works. I built the lib separate on XP mingw build environment and I
compiled and ran a fp test program (tst-ieee754.c) than compared the
results with standard gcc. The results are almost the same. The thing
even boots and draws okay. Floatlib.c is very old and I will soon
start testing with SoftFloat to replace the gcc soft float math.

So,,,,, is it posiable to build our build environment (RosBE) to
support full soft-float? So we can avoid more source in ReactOS.....
Well, except libm.a ~ 93k.

or,,,

Just support the hardware floating point and move on........


Thanks,
James
