What this is for

Ch 3 specified the regions; this shows them filled. The gp+0x00 through gp+0x0C slots hold the four VM segment-base pointers (LCL/ARG/THIS/THAT bases). The gp+0x40 la-ptr-table is the indirection layer that makes la rd, sym work without lui or auipc. Pick a scenario, click a region, and zoom the gp-window or the active stack frame to see real runtime values.
