Hi all, I've written a patch to extend FileCheck to support matching arithmetic expressions involving variable [1] (eg. to match REG+1 where REG is a variable with a numeric value). It was suggested to me in the review to introduce the concept of numeric variable and to allow for specifying the base the value are written in.
