Detailed Description

Location of a PHI instruction that is also a debug-info variable value, for the duration of register allocation.

Loaded by the PHI-elimination pass, and emitted as DBG_PHI instructions during VirtRegRewriter, with maintenance applied by intermediate passes that edit registers (such as coalescing and the allocator passes).
