Happy {$EXCESSPRECISION OFF}!
Just a notice: I’ve updated the XE2 single-precision floating point article after using the (up to now) undocumented {$EXCESSPRECISION OFF} directive, thanks to Allen Bauer for chiming in!
Executive summary: this directives enables use of single-precision SSE floating point instruction by the compiler, and brings their performance in line with expectations, making Delphi XE2 64bit compiler the new King of the Delphi Hill.
XE2 single-precision floating point (partial) disappointment…
In the previous episode, it appeared that Delphi XE2 64bit compiler was achieving quite good results, however, after further investigations, things may not be so clear-cut. Transcendental maths, which will be food for a another post, the subject of this one seems to be an issue with single-precision floating point maths.
GLScene source code used in FireMonkey?
Dan Bartlett spotted some GLScene source code in FireMonkey, see this thread in the Embarcadero forum for details, parts of the VectorGeometry.pas, Spline.pas and raycasting code have been identified. The code having been incorporated in closed-source code (KSDev’s, Delphi XE2) it hadn’t been spotted or reported so far (at least to my knowledge).
