Detailed Description

Represents the relative location of an instruction.

Instruction locations are specified by the line offset from the beginning of the function (marked by the line where the function header is) and the discriminator value within that line.

The discriminator value is useful to distinguish instructions that are on the same line but belong to different basic blocks (e.g., the two post-increment instructions in "if (p) x++; else y++;").
