I've got some javascript I need to rewrite in Perl and I'm stuck on the javascript >> operator which I believe is sign-propagating right bitwise shift. I found this node and it looked promising but none of the suggestions work for me.

I was thinking it may be because my ivsize is 8. Anyway, here are some examples from javascript of numbers shifted right 8 bits:

  -1 >> 8 = -1
  2140837940 >> 8 = 8362648
  -1934825877 >> 8 = -7557914
  -2004116368 >> 8 = -7828580
  1978483312 >> 8 = 7728450
  -293893010 >> 8 = -1148020

I cannot seem to reproduce this in Perl. Any ideas?
