Timon Gehr: > Fixed array assignment certainly won't cause any trouble.<
I don't know about the D front end, but those arrays have caused performance problems in my D2 code. Later I have taken more care, assigning items one after the other, writing: int[3] a = void; a[0] = ... a[1] = ... a[2] = ... Instead of: int[3] a = [..., ..., ...]; > An issue is that 32 bit x86 architectures do not necessarily provide any SSE > support. Most PCs have SSE2 support.

And with modern GCC-MinGW I usually compile code with those registers too on 32 bit Windows, using the right compiler switches. Bye, bearophile
