Matabeleland Modern-day Matabeleland is a region in Zimbabwe divided into three provinces: Matabeleland North, Bulawayo and Matabeleland South. These provinces are in the west and south-west of Zimbabwe, between the Limpopo and Zambezi rivers. The region is named after its inhabitants, the Ndebele people.

Use-define chain variable and all the uses, U, reachable from that definition without any other intervening definitions. Both UD and DU chains are created by using a form of static code analysis known as data flow analysis. Knowing the use-def and def-use chains for a program or subprogram is a prerequisite for many compiler optimizations, including constant propagation and common subexpression elimination. Making the use-define or define-use chains is a step in liveness analysis, so that logical representations of all the variables can be identified and tracked through the code. Consider the following snippet of code: Notice that codice_1 is assigned a
