/* __main (0x800100A0) -- crt0 constructor-runner, HANDWRITTEN assembly.
* Replaces the boot __main stub line in src/boot.c IN PLACE (order preserved:
* lands right after the `start` artifact, before __do_global_dtors). Same
* lane-2 file-scope __asm__ form already byte-gated in this TU for `start`,
* and used by banked StopRCnt/gfx2D_BG0_OBJ_658/FGO_06_OBJ_64/func_800D0440
* elsewhere in the tree. Per cookbook §265: ship NO C externs/prototype with
* the file-scope form -- the asm resolves symbols at link time; a guessed
* decl for a crt-reserved name is pure conflict risk.
*
* WHY ASM, NOT C: this TU builds -O0 per-file (the boot.c precedent), but
* __main's target bytes are -O2/handwritten-shaped code (loop state held in
* $s0/$s1 across the call, delay slots filled, zero local spill/reload) --
* no C body in this TU can produce them (a C draft compiles to 47 spilled
* -O0 insns).
*
* RECOVERED SEMANTICS (for the eventual real decomp):
* static int done; // D_80062998
* void __main(void) {
* if (!done) {
* done = 1;
* int *p = (int *)&start; // init-array base
* int n = 3; // count ships as literal zeros in the
* // target (splat renders `lui $s1,(0x0>>16)`
* // / `addiu $s1,$s1,0x0` -- its display of a
* // bare 32-bit literal, cf. `(0x80000000 >> 16)`
* // for raw 0080033C); emitted as plain zero
* // immediates, byte-identical, no relocation
* do { ((void (*)(void))*p)(); p++; n--; } while (n != 0);
* }
* }
* Maspsx rules honored per the start artifact: decimal immediates only,
* .set noreorder with explicit delay-slot nops, .ent/.end wrappers. */

/*
* main (0x80010178) -- the game's outer frame loop, compiled -O0 like the rest of
* src/boot.c (frame-pointer prologue, every global re-loaded per use).
*
* The four gcc-2.7.2 -O0 levers this needed (all NEW, none were in the cookbook):
*
* 1. TWO `register` locals, in declaration order, hold the two bases the whole
* function addresses through: $s0 = &D_800BA118 (loaded, NEVER used again --
* it must still be declared or the lui/addiu pair and the $s0 save/restore
* both vanish) and $s1 = D_800AF630. Same lever GameModeDispatch/func_8001099C
* already use in this TU; the >0x7FFF member offsets then assemble to the
* +0x10000/-0x5Cxx split.
*
* 2. `s32 pad[6];` -- 24 bytes of DECLARED-BUT-UNUSED stack. At -O0 gcc reserves a
* slot for every local whether or not it is read, and the target's frame is
* 0x38 (16 outgoing-arg + 24 vars + 16 saved). Without it the frame is 0x20 and
* every sp offset in the prologue/epilogue is wrong. The original's six words
* were presumably dead locals left in the source.
*
* 3. THE SHIFT-FORM MULTIPLY. Inside a MEMORY ADDRESS, `base + i * K` with a
* CONSTANT K expands (expand_expr MULT under EXPAND_SUM) to a `(mult reg K)`
* rtx that force_operand emits with the INDEX FIRST: `addu d,index,base`.
* Writing the same value as `base + ((i * (K>>n)) << n)` materialises the index
* into a plain register first, and the address then comes out BASE-first --
* `addu $v0,$s1,$a0` / `addu $at,$at,$v0` + `%lo(sym)($at)` -- which is what the
* target has. Measured: `p + i*12` -> `addu $4,$3,$2` (wrong), `p + ((i*3)<<2)`
* -> `addu $4,$2,$3` (right). Only address context is affected; in VALUE context
* (`(s32)(D_800A6610 + i*16384)`) the plain multiply already comes out base-first.
*
* 4. The three 12-byte-strided stores go through a struct pointer, not
* `*(s32 *)(p + ... + 8)`: only a COMPONENT_REF folds the member offset into the
* store (`sw $v1,0x8($v0)`); the pointer-arithmetic spelling materialises it as
* a separate `addiu`.
*
* Two smaller ones: `(*(u16 *)(p + 0xA3A8))++` emits the extra `addu $v0,$v1,$zero`
* that `+= 1` does not; and CatPrim's second argument is written
* `<load> + D_80074778 * 4` (NOT `D_80074778 * 4 + <load>`) -- with a MEM as operand
* 0 gcc emits the MEM's address first, then operand 1, then the load, and the addu
* comes out operand-1-first, exactly the target's interleave.
*
* The two scratchpad-stack switches around func_80015498/func_8001C00C/func_800D25FC
* are the §261 idiom: the $sp repointing is inline asm, the calls stay C (so -O0
* supplies the `jal` + delay-slot nop). $a2 here, not the overlays' $v1.

* The target's D_800629D6 index is TWO chained anonymous x2 expansions: lw;copy;sll;copy;sll (expand_mult's
* copy_to_mode_reg + shift, expmed.c:2227/2244, twice, adjacent). §474 proved no TREE can carry MULT(MULT(i,2),2):
* fold-const.c:882 split_tree merges it, and every escape (stmt-expr note, register decl (use) brackets) costs a suid.
* The escape §474 did not consider is that the nested MULT need not exist at TREE level at all. In the EXPAND_SUM
* (address) route, expr.c:5368 "Apply distributive law if OP0 is x+c" rewrites (x + c) * k with x ALREADY a (mult ..)
* rtx into (plus (mult (mult X 2) 2) c*k) -- a nested MULT built AFTER fold, which fold never sees; fold has no
* MULT-over-PLUS distribution, so `(i*2 + 1) * 2` survives as MULT(PLUS(MULT(i,2),1),2). The spurious +2 is cancelled
* by the `- 2` on the index: both_summands (expr.c:5248) + simplify_binary_operation/plus_constant fold sym-2+2 into
* the BARE symbol, so the address is (plus (mult (mult X 2) 2) sym) -> force_operand expands the two multiplies
* back-to-back and expand_binop's copy_to_mode_reg(sym) gives the target's `la $a0; addu $v1,$v1,$a0; lbu $a0,0($v1)`.
* No note, no variable: stupid.c's born+2 rule 2-colours the chain $v1/$a0 exactly as the target. Verified: match_one
* MATCH 192/192 and rtu_match MATCH in src/boot.c (--o0). Semantics: (i*2+1)*2-2 == i*4. */

/* func_8001212C -- boot (-O0). Builds two 0x18-byte SPRT-with-own-tpage prims at
* the D_800A5E60 prim-buffer cursor and addPrim()s each onto OT word [1] of the
* frame's ordering table (D_800A6610 + gameFrame*0x4000), then republishes the
* advanced cursor.
*
* -O0 spellings that are load-bearing (all byte-proven here):
* - `register u8 *base = D_800AF630;` far-offset base: cookbook ADDENDUM(c) to
* §261a -- lands caller-saved ($v0) with no calls, and the >0x7FFF member
* access assembles to lui $at,1 / addu $at,$v0,$at / lhu -0x5C2E($at).
* - `* 0x4000` (the MULTIPLY, not `<< 14`): the mul-style expansion emits the
* `addu $a0,$v1,$zero` copy of the index before the sll -- ADDENDUM(b) to
* §261a, read in the mirror direction (there `q << 2` was wanted, here the
* multiply is).
* - offset 4 is `((u32 *)p)[1]`, every other field is a member lvalue: §127 /
* its ADDENDUM -- the constant-offset fold keys on the COMPONENT_REF tree
* shape, so the ARRAY_REF form is what materialises `addiu $v1,$a0,0x4` +
* a 0-displacement `sw`, which is exactly what the target shows there.
* - `p++` and NOT `p = p + 1`: the increment expands add-into-fresh-pseudo +
* `addu $a0,$v1,$zero` copy-back before the spill store (§261a's copy row).
* `p = p + 1` / `p += 1` / `&p[1]` / the (u8*) cast all fold that copy away
* (-1 ins each). This was the whole residual: 175 ins vs 177.
* - the 24-bit `addr` bitfield reproduces libgpu's setaddr()/getaddr() RMW:
* and 0xFFFFFF (extract) + and 0xFFFFFF (store mask) + and 0xFF000000 + or.
