nx_js_octane_splay.nx source

1// nx_js_octane_splay.nx -- run the REAL Octane Splay benchmark (unmodified Google source, harness stubbed) on 2// our sovereign VM/JIT. Splay self-validates in SplayTearDown (throws Error on wrong tree size/sort) so a clean 3// "SPLAY_OK" return means the splay-tree insert/remove/splay/traverse all ran correctly. Exercises: object 4// literals, Math.random, float keys + float compares, prototype methods, closures/callbacks, do-while, throw, 5// Array.push, String(float). PARSE-first to split syntax gaps from runtime feature gaps. expect_exit: 0 6// license_tier: ORIGINAL 7import "nx_js_vm.nx" 8const K_MAGIC_262144: i64 = 262144 9const K_MAGIC_23908: i64 = 23908 10func ow(s: *u8) -> i64 { var n: i64 = 0; while s[n] != (0 as u8) { n = n + 1 } sys_write(1, s, n); return 0 } 11func on(v: i64) -> i64 { if v==0 { sys_write(1,"0" as *u8,1); return 0 } var m: i64=v; if m<0 { sys_write(1,"-" as *u8,1); m=0-m } let t: *u8=sys_mmap(24); var k: i64=0; while m>0 { t[k]=(48+(m%10)) as u8; m=m/10; k=k+1 } let o: *u8=sys_mmap(24); var q: i64=k-1; var x: i64=0; while q>=0 { o[x]=t[q]; x=x+1; q=q-1 } sys_write(1,o,x); return 0 } 12func main(argc: i64, argv: *i64) -> i64 { 13 ow("=== nx_js_octane_splay: real Octane Splay on our sovereign VM/JIT ===\n" as *u8) 14 let fd: i64 = sys_openat_rd("knowledge/octane/splay_eng.js\x00" as *u8) 15 if fd < 0 { ow(" RED: cannot open knowledge/octane/splay_eng.js\n" as *u8); return 1 } 16 let cap: i64 = K_MAGIC_262144 17 let buf: *u8 = sys_mmap(cap + 8) 18 var total: i64 = 0 19 var done: i64 = 0 20 while done == 0 { 21 let n: i64 = sys_read(fd, ((buf as i64) + total) as *u8, cap - total) 22 if n <= 0 { done = 1 } else { total = total + n } 23 } 24 sys_close(fd) 25 buf[total] = 0 as u8 26 ow(" loaded splay_eng.js: "); on(total); ow(" bytes\n" as *u8) 27 28 // PARSE-ONLY first: syntax gap vs runtime feature gap. 29 let ctxbox: *i64 = sys_mmap(16) as *i64 30 let prog: i64 = jp_parse_source(buf, total, ctxbox) 31 let pctx: *i64 = (ctxbox[0]) as *i64 32 let pst: *i64 = jp_pst(pctx) 33 if pst[PST_ERR] == 1 { ow(" PARSE ERROR (a syntax feature is missing)\n" as *u8) } else { ow(" PARSE OK -> any failure is a RUNTIME feature\n" as *u8) } 34 35 let out: *i64 = sys_mmap(16) as *i64 36 let t0: i64 = sys_now_us() 37 let rc: i64 = compile_run(buf, out) 38 let t1: i64 = sys_now_us() 39 ow(" compile_run rc="); on(rc); ow(" result tag="); on(out[0]) 40 if out[0] == VAL_STR { ow(" '"); sys_write(1, ev_str_bytes((out[1]) as *i64), ev_str_len((out[1]) as *i64)); ow("'") } 41 ow("\n" as *u8) 42 43 var okr: i64 = 0 44 if rc == 0 { if out[0] == VAL_STR { 45 let rb: *u8 = ev_str_bytes((out[1]) as *i64) 46 let rl: i64 = ev_str_len((out[1]) as *i64) 47 if rl == 8 { okr = 1; var i: i64 = 0; let exp: *u8 = "SPLAY_OK" as *u8; while i < 8 { if (rb[i] & 0xff) != (exp[i] & 0xff) { okr = 0; i = 8 } else { i = i + 1 } } } 48 } } 49 if okr == 0 { ow("=== RED: Splay did not complete (feature gap or self-validation throw) ===\n" as *u8); return 1 } 50 var us: i64 = t1 - t0 51 if us < 1 { us = 1 } 52 let v8: i64 = K_MAGIC_23908 // node v22 best-of-5 (warmed) on this box; ours is cold parse+1run (not apples-to-apples) 53 ow(" ours(parse+1 run)="); on(us); ow("us V8(warm best5)="); on(v8); ow("us (Splay stresses GC/alloc = our weak spot: no real GC)\n" as *u8) 54 ow("=== GREEN: we RAN real Octane Splay -- tree self-validated (size 8000, sorted, unique) ===\n" as *u8) 55 return 0 56}
