Bison can not create LR table

[zdprikryl]

Hello,
If I write grammar like below, than bison prints this:

conflicts: 1 reduce/reduce
warning: rule never reduced because of conflicts: ireg_MOVE_INDIRECT_A: ireg
warning: rule never reduced because of conflicts:
ireg_MOVE_INDIRECT_DATA: ireg

But grammar is LR for sure, because I can construct it by hand on paper.

Thanks
