SetEQ RAX; ret;` に対応し、`if( a==3 )` は `CmpX86 RAX,#3; jeq;` に対応します。 + +## RISC-V 移植 + +`node/cpus/riscv` ディレクトリには RISC-V への移植 `riscv.java` があります。32個の64ビット GPR と32個の浮動小数点レジスタをサポートします。理想化された Simple の Sea-of-Nodes から riscv 演算を対応付けるパターンマッチャがあります。現在の対象は `RVA23U64` です。 + +### 通常の命令選択 + +**X86_64_V2** と同様に動作します。riscv には *複雑な* アドレッシングモードがないため、ほとんどの場合は貪欲なパターンマッチを適用しません。特別な動作のない演算は、単純に検索します。 + +### 制限された ISA + +RISC-V は単純なアドレッシングモードとオーバーロードを備える、制限された ISA です。たとえば `lea` はありません。 + +### 分岐 + +`x86_64_v2` の分岐は、フラグを設定する比較命令と、そのフラグを使うジャンプ命令を必要とします。一方 RISC-V は、必要なオペランドをすべて分岐命令そのものに含め、別の比較ステップを不要にします。 + +例: + +``` +beq x10, x11, some_label +``` + +`CBranchRISC` がこの動作を実装します。 + +### R フラグを持たない + +RISC-V には R フラグがありません。同様の機能を得るには、比較結果に応じてレジスタ値を明示的に設定できます。 + +``` +xor a0, a0, a1 +seqz a0, a0 +``` + +最初の `xor` の後、`a0` と `a1` が等しければ `a0` はゼロになります。`seqz` 命令は、前の演算で `a0` がゼロになっていれば `a0` を1に設定します。これは `nodes/cpus/riscv` 移植の `SetRISC` に対応します。 + +### 固定長命令 + +RISC-V の命令長は（ほとんどの場合）32ビット固定であり、エンコーディング側で変位を活用できます。 + +例: + +``` +flw fa5, 0(a0) +flw fa4, 12(a0) +fadd.s fa0, fa5, fa4 +``` + +（`flw` の前にロードは必要ありません。） + +### ABI 名（レジスタ） + +`RISC-V` の汎用レジスタ（`GPR`）は `x0` から `x31`、浮動小数点レジスタは `f0` から `f31` です。 + +読みやすさを高め、呼び出し規約と整合させるため、RISC-V はレジスタの ABI 名を定義し、生の番号よりも直感的な別名を提供します。 + +| レジスタ | 別名 | 用途 | 保存する側 | +|----------|-------|------------------------------|----------| +| x10 | a0 | 関数の引数／戻り値 | 呼び出し側 | +| x11 | a1 | 関数の引数／戻り値 | 呼び出し側 | +| x12 | a2 | 関数の引数 | 呼び出し側 | +| x13 | a3 | 関数の引数 | 呼び出し側 | +| x14 | a4 | 関数の引数 | 呼び出し側 | +| x15 | a5 | 関数の引数 | 呼び出し側 | +| x16 | a6 | 関数の引数 | 呼び出し側 | +| x17 | a7 | 関数の引数 | 呼び出し側 | + +関数に引数を渡すとき、呼び出し側からの最初の8個の引数はレジスタ `a0` から `a7` で渡します。 + +### 浮動小数点値のロード + +現在、浮動小数点定数は、浮動小数点レジスタに変換する前に、まず `integer GPR` にロードします。この処理は RA フェーズで次のように書き換えます。 + +```` +lui a0, 262144 +fmv.w.x fa0, a0 +```` + +非定数値には、GPR と FPR の両方をサポートする、より広いレジスタマスクを使います。この実装は `nodes/cpus/riscv/LoadRISC` にあります。 diff --git a/docs/chapter19/README.md b/docs/chapter19/README.md new file mode 100644 index 00000000..4d9e0572 --- /dev/null +++ b/docs/chapter19/README.md @@ -0,0 +1,236 @@ +# Chapter 19: Instruction Selection and Portable Compilation + +English | [日本語](README.ja.md) + +[Previous: Chapter 18](../chapter18/README.md) | +[Next: Chapter 20](../chapter20/README.md) + +You can also read [this chapter](https://github.com/SeaOfNodes/Simple/tree/linear-chapter19) in a linear Git revision history on the [linear](https://github.com/SeaOfNodes/Simple/tree/linear) branch and [compare](https://github.com/SeaOfNodes/Simple/compare/linear-chapter18...linear-chapter19) it to the previous chapter. + + +The grammar is unchanged from [Chapter 18](../chapter18/18-grammar.md). + +## Meta-Issues / Code-Dev Issues of Instruction Selection, Register Allocation and Encodings + +The output of Instruction Selection - the mapping from idealized Simple Nodes +to machine-specific ones - is difficult to test in bulk without an execution +strategy. We won't have an execution strategy until all three of Instruction +Selection, Register Allocation and Encodings are done. Hence in and around the +completion of Encoding we expect to find lots of bugs in Instruction Selection +and Register Allocation. We certainly hand-inspect the output and fix obvious +problems, but still lots of bugs linger until we can actually run the code. + +This means that other chapters have updates and bug-fixes to the work being +described here. + + +## Portable Compilation + +A new abstract `Machine` class is added, one per unique CPU port. `Machine` +defines a name for the port, names for all registers, and how to generate +machine Nodes from *ideal* Nodes. `Machine` also allows generating *split* ops +and *jumps*, both used by the machine independent compiler parts during +code-gen. + +A new CallingConv enum is added, to allow picking between various calling conventions. + +## The Instruction Selection Phase + +A new *InstructionSelection* compile phase is added before *Global Code +Motion*. It is optional, but will replace the *ideal* Nodes with machine- +specific variants. Instruction selection is called with the target CPU name; +the porting code is looked up and used then. This allows the Java +implementation at least the ability to add CPU ports lazily. + + +## Machine Specific Nodes + +We add a notion of "machine specific" Nodes, which implement the `MachNode` +interface. `MachNode` nodes define incoming and outgoing registers for every +instruction, their bit encodings and user representations. Later we'll add +function unit information for a better local schedule. + + +## Clean up CodeGen compile driver + +More static globals move into the CodeGen object, which is passed around at all +the top level drivers. It's not passed into the Node constructors, hence not +into the idealize() calls, which remains the majority of cases needing a static +global. In short the compiler gets a lot more functional, and a big step +towards concurrent or multi-threaded compilation. + + +## Memory through instruction selection + +The parser carries one `$mem` binding. BulkMemPhi splits aliases on demand into +parallel MemPhis, while MemMerge packages a default memory and explicit slices. +Both machine selectors preserve these node classes and their alias information; +they do not turn memory Phis into ordinary value Phis. + +This chapter lowers nonzero constructor values into explicit Stores, keeping the +allocation itself a zeroing operation. New consumes `{ctrl, $mem, size}` and +produces `{ptr, $mem}`. Its input is a partial MemMerge covering the allocated +struct's aliases; its single memory result covers those same aliases. The parser +preserves unrelated memory in the surrounding aggregate. The allocation's size +register is input 2, its pointer result is output 0, and memory has no register. + +Selected memory operations retain their field alias even when an x86 arithmetic +or comparison instruction absorbs a Load. Global scheduling therefore finds +anti-dependencies through the common MemOpNode, following the relevant slice +through MemMerge. Memory-result instructions are writers; other memory operations +are readers. Trailing ordering edges on writers impose no register requirement. +The simple one-step Load guard used when factoring Phis is unchanged. + +Calls still consume and produce whole memory. They terminate their blocks, so +scheduling raises a read before a Call without adding inputs to its argument +list. Direct machine calls embed their constant target and retain only control, +memory, and argument inputs. + + +## Registers and Register Masks + +`Machines` define registers as small dense integers. The Register Allocator +will use these numbers when allocating. The mappings from small integers to +machine registers is up to the porter, but there's usually an obvious +one-to-one. For the X86, RAX will be register 0, RCX register 1 and so on up +to the 16 GPRs. The XMM register numbers start at 16 and go through 31. Register numbers +must be unique; this is how the register allocator tracks them. + +A `RegMask` Register Mask class holds onto bitsets of allowed registers. Most +machine ops are limited to some subset of all registers, and the allowed sets +are written as a RegMask. Most RegMasks are immutable, e.g. the set of allowed +registers into a `Mul` operation, but the register allocator will make +extensive use of mutable register sets. + +Calling conventions dictate many fixed registers, and in practice tend to +really "bind up" the set of allowed registers. + + +## An X86_64_V2 port, with SystemV or Win64 calling conventions + +In the `node/cpus/x86_64_v2` directory is a `x86_64_v2.java` port to an X86 64 +V2. This port supports 16 64-bit GPRs, 16 XMM registers and the X86 flags. +There is a pattern matcher for matching X86 ops from idealized Simple +Sea-of-Nodes. Except for the addressing modes pattern matcher matches nearly +one-for-one X86 ops from ideal nodes. + +### Normal instruction selection + +The instSelect phase walks the ideal graph, and maintains a mapping +from ideal-to-machine ops. It does a greedy pattern match, first come first +match. Ops without any special behavior simply do the local lookup e.g. an +`Mul` exactly matches to an X86 `MulX86` directly. The RHS of most matches can +be an immediate constant, matching an immediate-flavored version (`MulIX86`). + +### Addressing Modes + +For many X86 operations, if one of the inputs is a `Load`, the X86 can use an +op-from-memory variant. There's a specific `address()` call in the X86 matcher +that looks for the various kinds of addressing modes and will build memory- +specific variations. These all need to be called out specifically, but with a +simple one-line match and one-line allocation of the memory version. + +### Compare vs Jmp + +In simple, a `BoolNode` produces a `0/1` value. On an X86 this is done with +the `Cmp/SetXX` opcode sequence. The X86 `Jxx` takes in `FLAGS` and not a +`0/1`, so the `Jxx` will skip the `SetXX` and directly use the `Cmp`. Using +the ideal `Bool` directly will require the `SetXX`. i.e. `return a==3` will +match to a `CmpX86 RAX,#3; SetEQ RAX; ret;` whereas a `if( a==3 )` will match +to a `CmpX86 RAX,#3; jeq;` + +## RISC-V port + +In the `node/cpus/riscv` directory is a `riscv.java` port to a RISC-V. +This port supports 32 64-bit GPRs, and 32 floating-point registers. +There is a pattern matcher for matching riscv ops from idealized Simple +Sea-of-Nodes. Currently, we are targeting `RVA23U64`. + +### Normal instruction selection + +Works the same way as **X86_64_V2**, since riscv doesn't have *complex* addressing modes, greedy +pattern matching doesn't apply to most of the cases. Ops without any special behavior simply do the lookup. + +### Restricted ISA +RISC-V is a restricted ISA with simple addressing modes and overloads. +E.g `lea` is not present. + + +### Branching + +In `x86_64_v2`, branching requires a comparison instruction to set flags, +followed by a jump instruction that uses those flags. In contrast, RISC-V +includes all necessary operands within the branch instruction itself, +eliminating the need for a separate comparison step. + +E.g +``` +beq x10, x11, some_label +``` + +`CBranchRISC` implements this behavior. + +### No R-Flags + +No R-flags exist in RISC-V. To obtain similar functionality: +We can set the value of registers based on the result of the comparison this way explicitly. +``` +xor a0, a0, a1 +seqz a0, a0 +``` +After the first `xor` - `a0` will be zero if `a0` and `a1` are equal. +The `seqz` instruction will set `a0` to 1 if `a0` is zero from the previous operation. +This matches `SetRISC` in the `nodes/cpus/riscv` port. + +### Fixed instruction length + +RISC-V instructions have fixed length of 32 bits(in most cases) which means +that we can benefit from displacements in the encoding side. + +E.g +``` +flw fa5, 0(a0) +flw fa4, 12(a0) +fadd.s fa0, fa5, fa4 +``` +(No load is needed prior to `flw`) + +### ABI names(registers) +In `RISC-V`, general-purpose registers (`GPRs`) range from `x0` to `x31`, and floating-point registers range +from `f0` to `f31`. + +To enhance readability and align with calling conventions, RISC-V defines ABI names for registers, providing more intuitive aliases +instead of raw register numbers. + + + +| Register | Alias | Usage | Saved By | +|----------|-------|------------------------------|----------| +| x10 | a0 | Function arguments/return values | Caller | +| x11 | a1 | Function arguments/return values | Caller | +| x12 | a2 | Function arguments | Caller | +| x13 | a3 | Function arguments | Caller | +| x14 | a4 | Function arguments | Caller | +| x15 | a5 | Function arguments | Caller | +| x16 | a6 | Function arguments | Caller | +| x17 | a7 | Function arguments | Caller | + +When passing in arguments to a function, the first 8 arguments from the caller are passed in registers `a0` to `a7`. + +### Load floats +Currently, floating-point constants are first loaded into an `integer GPR` before being converted into a floating-point register. +This process is rewritten in the RA stage as: + + +```` +lui a0, 262144 +fmv.w.x fa0, a0 +```` +For non-constant values, we use a broader register mask that +supports both GPRs and FPRs.
