This is just what I have been working on : an assume() routine
which modifies the compiler’s behaviour so that later code
generation is optimised further by the knowledge gained by
declarations of truths in assume( cond ) statements. Now you’ve
been kind enough to give me the missing piece for ldc, I can add
LDC support in too next.
Thank you so very much for your generous help guys. I’m an
experienced professional asm and C programmer but I’m just
starting out with D, and due to my poor health my memory and
concentration are shot.
