Title 1 calls macros ~1.3 million times a second; most were replayed from the macro memo, whose lookups missed the CPU caches inside the GPU thread (~8%), and the rest interpreted. macro_turing_jit.h compiles all of the uploaded macro memory with Xbyak: each instruction a block falling through to the next, branches and loops through a jump table, with the interpreter's semantics (lanes reading operands before either writes, predication as two variants, the END delay slot, loops, carry). Loop checks only where a loop can end, END checks only after an END, the instruction limit counted on indirect jumps. Emits and register reads call back into C++. It is recompiled when the macro code changes and used for 3D and compute macros on x86-64; EDEN_NX2_MME_JIT=0 goes back to the memo and the interpreter. Checked against the interpreter on 200,000 recorded calls (registers, data RAM, every method write, FIFO use): identical. In the game: macro calls 148 ns instead of 174 (two profiled runs each), no failures, 0 crashes in 3 runs. NX2_GPU_THREAD_SPLIT.md describes the next step, splitting the GPU thread. |
