- hello
- Having installed successfully 386BSD running Xwindow in 1024x768
- on a 486/25 or/33 with XL wonder, the next step for us was performances.
- As our private benchmark tests did not satisfies us, the question is :
-
- a) Does 386BSD use the internal Floating Point Processor(FPP) of the 486?
-
- b) Does libm.a emulate the FPP operation to be portable on 386 w/o 387?
-
- c) Is there some tools to check if the FPP is being used?
-
- d) using gdb> info float<cr> does return me NOTHING! Is is suppose to
- to tell me something?
-
- e) Should I get my hand on a special library?
