Detailed Description

Replacement definition for a debug instruction reference.

Made up of a source instruction / operand pair, destination pair, and a qualifying subregister indicating what bits in the operand make up the substitution. of %1: %0:gr32 = someinst, debug-instr-number 1 %1:gr16 = %0.some_16_bit_subreg, debug-instr-number 2 Would receive the substitution {{2, 0}, {1, 0}, $subreg}, where $subreg is the subregister number for some_16_bit_subreg.
