Introduction to the Go compiler's SSA backend

This package contains the compiler's Static Single Assignment form component. If you're not familiar with SSA, its Wikipedia article is a good starting point.

It is recommended that you first read cmd/compile/README.md if you are not familiar with the Go compiler already. That document gives an overview of the compiler, and explains what is SSA's part and purpose in it.

Key concepts

The names described below may be loosely related to their Go counterparts, but note that they are not equivalent. For example, a Go block statement has a variable scope, yet SSA has no notion of variables nor variable scopes.

It may also be surprising that values and blocks are named after their unique sequential IDs. They rarely correspond to named entities in the original code, such as variables or function parameters. The sequential IDs also allow the compiler to avoid maps, and it is always possible to track back the values to Go code using debug and position information.

Values

Values are the basic building blocks of SSA. Per SSA's very definition, a value is defined exactly once, but it may be used any number of times. A value mainly consists of a unique identifier, an operator, a type, and some arguments.

An operator or Op describes the operation that computes the value. The semantics of each operator can be found in gen/*Ops.go. For example, OpAdd8 takes two value arguments holding 8-bit integers and results in their addition. Here is a possible SSA representation of the addition of two uint8 values:

// var c uint8 = a + b
v4 = Add8 <uint8> v2 v3

A value's type will usually be a Go type. For example, the value in the example above has a uint8 type, and a constant boolean value will have a bool type. However, certain types don't come from Go and are special; below we will cover memory, the most common of them.

See value.go for more information.

Memory types

memory represents the global memory state. An Op that takes a memory argument depends on that memory state, and an Op which has the memory type impacts the state of memory. This ensures that memory operations are kept in the right order. For example:

// *a = 3
// *b = *a
v10 = Store <mem> {int} v6 v8 v1
v14 = Store <mem> {int} v7 v8 v10

Here, Store stores its second argument (of type int) into the first argument (of type *int). The last argument is the memory state; since the second store depends on the memory value defined by the first store, the two stores cannot be reordered.

See cmd/compile/internal/types/type.go for more information.

Blocks

A block represents a basic block in the control flow graph of a function. It is, essentially, a list of values that define the operation of this block. Besides the list of values, blocks mainly consist of a unique identifier, a kind, and a list of successor blocks.

The simplest kind is a plain block; it simply hands the control flow to another block, thus its successors list contains one block.

Another common block kind is the exit block. These have a final value, called control value, which must return a memory state. This is necessary for functions to return some values, for example - the caller needs some memory state to depend on, to ensure that it receives those return values correctly.

The last important block kind we will mention is the if block. Its control value must be a boolean value, and it has exactly two successor blocks. The control flow is handed to the first successor if the bool is true, and to the second otherwise.

Here is a sample if-else control flow represented with basic blocks:

// func(b bool) int {
// 	if b {
// 		return 2
// 	}
// 	return 3
// }
b1:
  v1 = InitMem <mem>
  v2 = SP <uintptr>
  v5 = Addr <*int> {~r1} v2
  v6 = Arg <bool> {b}
  v8 = Const64 <int> [2]
  v12 = Const64 <int> [3]
  If v6 -> b2 b3
b2: <- b1
  v10 = VarDef <mem> {~r1} v1
  v11 = Store <mem> {int} v5 v8 v10
  Ret v11
b3: <- b1
  v14 = VarDef <mem> {~r1} v1
  v15 = Store <mem> {int} v5 v12 v14
  Ret v15

See block.go for more information.

Functions

A function represents a function declaration along with its body. It mainly consists of a name, a type (its signature), a list of blocks that form its body, and the entry block within said list.

When a function is called, the control flow is handed to its entry block. If the function terminates, the control flow will eventually reach an exit block, thus ending the function call.

Note that a function may have zero or multiple exit blocks, just like a Go function can have any number of return points, but it must have exactly one entry point block.

Also note that some SSA functions are autogenerated, such as the hash functions for each type used as a map key.

For example, this is what an empty function can look like in SSA, with a single exit block that returns an uninteresting memory state:

foo func()
  b1:
    v1 = InitMem <mem>
    Ret v1

See func.go for more information.

Compiler passes

Having a program in SSA form is not very useful on its own. Its advantage lies in how easy it is to write optimizations that modify the program to make it better. The way the Go compiler accomplishes this is via a list of passes.

Each pass transforms a SSA function in some way. For example, a dead code elimination pass will remove blocks and values that it can prove will never be executed, and a nil check elimination pass will remove nil checks which it can prove to be redundant.

Compiler passes work on one function at a time, and by default run sequentially and exactly once.

The lower pass is special; it converts the SSA representation from being machine-independent to being machine-dependent. That is, some abstract operators are replaced with their non-generic counterparts, potentially reducing or increasing the final number of values.

See the passes list defined in compile.go for more information.

Playing with SSA

A good way to see and get used to the compiler's SSA in action is via GOSSAFUNC. For example, to see func Foo's initial SSA form and final generated assembly, one can run:

GOSSAFUNC=Foo go build

The generated ssa.html file will also contain the SSA func at each of the compile passes, making it easy to see what each pass does to a particular program. You can also click on values and blocks to highlight them, to help follow the control flow and values.

Hacking on SSA

While most compiler passes are implemented directly in Go code, some others are code generated. This is currently done via rewrite rules, which have their own syntax and are maintained in gen/*.rules. Simpler optimizations can be written easily and quickly this way, but rewrite rules are not suitable for more complex optimizations.

To read more on rewrite rules, have a look at the top comments in gen/generic.rules and gen/rulegen.go.

Similarly, the code to manage operators is also code generated from gen/*Ops.go, as it is easier to maintain a few tables than a lot of code. After changing the rules or operators, see gen/README for instructions on how to generate the Go code again.

Functions

func Compile

func Compile(f *Func)

Compile is the main entry point for this package. Compile modifies f so that on return:

· all Values in f map to 0 or 1 assembly instructions of the target architecture
· the order of f.Blocks is the order to emit the Blocks

IsGlobalAddr reports whether v is known to be an address of a global.

func IsNewObject

func IsNewObject(v *Value, mem *Value) bool

IsNewObject reports whether v is a pointer to a freshly allocated & zeroed object at memory state mem. TODO: Be more precise. We really want "IsNilPointer" for the particular field in question. Right now, we can only detect a new object before any writes have been done to it. We could ignore non-pointer writes, writes to offsets which are known not to overlap the write in question, etc.

func IsReadOnlyGlobalAddr

func IsReadOnlyGlobalAddr(v *Value) bool

IsReadOnlyGlobalAddr reports whether v is known to be an address of a read-only global.

func IsSanitizerSafeAddr

func IsSanitizerSafeAddr(v *Value) bool

func IsStackAddr

func IsStackAddr(v *Value) bool

IsStackAddr reports whether v is known to be an address of a stack slot.

func LosesStmtMark

func LosesStmtMark(as obj.As) bool

LosesStmtMark reports whether a prog with op as loses its statement mark on the way to DWARF. The attributes from some opcodes are lost in translation. TODO: this is an artifact of how funcpctab combines information for instructions at a single PC. Should try to fix it there.

func NeedsFixUp

func NeedsFixUp(v *Value) bool

NeedsFixUp reports whether the division needs fix-up code.

func PhaseOption

func PhaseOption(phase, flag string, val int, valString string) string

PhaseOption sets the specified flag in the specified ssa phase, returning empty string if this was successful or a string explaining the error if it was not. A version of the phase name with "_" replaced by " " is also checked for a match. If the phase name begins a '~' then the rest of the underscores-replaced-with-blanks version is used as a regular expression to match the phase name(s).

Special cases that have turned out to be useful:

ssa/check/on enables checking after each phase
ssa/all/time enables time reporting for all phases

See gc/lex.go for dissection of the option string. Example uses:

GO_GCFLAGS=-d=ssa/generic_cse/time,ssa/generic_cse/stats,ssa/generic_cse/debug=3 ./make.bash

BOOT_GO_GCFLAGS=-d='ssa/~^.*scc$/off' GO_GCFLAGS='-d=ssa/~^.*scc$/off' ./make.bash

type Edge

type Edge struct {

if k then c else c

c:

v = Phi(x, y)

Then the indexes tell you whether x is chosen from the if or else branch from b.

b.Succs = [{c,0},{c,1}]
c.Preds = [{b,0},{b,1}]

means x is chosen if k is true.

type FuncDebug struct {
	// Slots is all the slots used in the debug info, indexed by their SlotID.
	Slots []LocalSlot
	// The user variables, indexed by VarID.
	Vars []GCNode
	// The slots that make up each variable, indexed by VarID.
	VarSlots [][]SlotID
	// The location list data, indexed by VarID. Must be processed by PutLocationList.
	LocationLists [][]byte

	// Filled in by the user. Translates Block and Value ID to PC.
	GetPC func(ID, ID) int64
}

A FuncDebug contains all the debug information for the variables in a function. Variables are identified by their LocalSlot, which may be the result of decomposing a larger variable.

func BuildFuncDebug

func BuildFuncDebug(ctxt *obj.Link, f *Func, loggingEnabled bool, stackOffset func(LocalSlot) int32) *FuncDebug

BuildFuncDebug returns debug information for f. f must be fully processed, so that each Value is where it will be when machine code is emitted.

func (*FuncDebug) PutLocationList

PutLocationList adds list (a location list in its intermediate representation) to listSym.

type FuncLines

type FuncLines struct {
	Filename    string
	StartLineno uint
	Lines       []string
}

FuncLines contains source code for a function to be displayed in sources column.

type GCNode

type GCNode interface {
	Typ() *types.Type
	String() string
	IsSynthetic() bool
	IsAutoTmp() bool
	StorageClass() StorageClass
}

interface used to hold a *gc.Node (a stack variable). We'd use *gc.Node directly but that would lead to an import cycle.

type HTMLWriter

type HTMLWriter struct {
	Logger
	// contains filtered or unexported fields
}

func NewHTMLWriter

func NewHTMLWriter(path string, logger Logger, funcname, cfgMask string) *HTMLWriter

func (*HTMLWriter) WriteColumn

func (w *HTMLWriter) WriteColumn(phase, title, class, html string)

WriteColumn writes raw HTML in a column headed by title. It is intended for pre- and post-compilation log output.

func (*HTMLWriter) WriteFunc

func (w *HTMLWriter) WriteFunc(phase, title string, f *Func)

WriteFunc writes f in a column headed by title. phase is used for collapsing columns and should be unique across the table.

func (*HTMLWriter) WriteSources

func (w *HTMLWriter) WriteSources(phase string, all []*FuncLines)

WriteSources writes lines as source code in a column headed by title. phase is used for collapsing columns and should be unique across the table.

func (w *HTMLWriter) WriteString(s string)

type ID

type ID int32

type LocPair

type LocPair [2]Location

func (LocPair) String

func (t LocPair) String() string

type LocalSlot

type LocalSlot struct {
	N    GCNode      // an ONAME *gc.Node representing a stack location.
	Type *types.Type // type of slot
	Off  int64       // offset of slot in N

	SplitOf     *LocalSlot // slot is a decomposition of SplitOf
	SplitOffset int64      // .. at this offset.
}

A LocalSlot is a location in the stack frame, which identifies and stores part or all of a PPARAM, PPARAMOUT, or PAUTO ONAME node. It can represent a whole variable, part of a larger stack slot, or part of a variable that has been decomposed into multiple stack slots. As an example, a string could have the following configurations:

stack layout              LocalSlots

Optimizations are disabled. s is on the stack and represented in its entirety. [ ------- s string ---- ] { N: s, Type: string, Off: 0 }

s was not decomposed, but the SSA operates on its parts individually, so there is a LocalSlot for each of its fields that points into the single stack slot. [ ------- s string ---- ] { N: s, Type: *uint8, Off: 0 }, {N: s, Type: int, Off: 8}

s was decomposed. Each of its fields is in its own stack slot and has its own LocalSLot. [ ptr *uint8 ] [ len int] { N: ptr, Type: *uint8, Off: 0, SplitOf: parent, SplitOffset: 0},

{ N: len, Type: int, Off: 0, SplitOf: parent, SplitOffset: 8}
parent = &{N: s, Type: string}

func (LocalSlot) String

func (s LocalSlot) String() string

type Location

type Location interface {
	String() string // name to use in assembly templates: AX, 16(SP), ...
}

A place that an ssa variable can reside.

type Logger

type Logger interface {
	// Logf logs a message from the compiler.
	Logf(string, ...interface{})

	// Log reports whether logging is not a no-op
	// some logging calls account for more than a few heap allocations.
	Log() bool

	// Fatal reports a compiler error and exits.
	Fatalf(pos src.XPos, msg string, args ...interface{})

	// Warnl writes compiler messages in the form expected by "errorcheck" tests
	Warnl(pos src.XPos, fmt_ string, args ...interface{})

	// Forwards the Debug flags from gc
	Debug_checknil() bool
}

type Op

type Op int32

An Op encodes the specific operation that a Value performs. Opcodes' semantics can be modified by the type and aux fields of the Value. For instance, OpAdd can be 32 or 64 bit, signed or unsigned, float or complex, depending on Value.Type. Semantics of each op are described in the opcode files in gen/*Ops.go. There is one file for generic (architecture-independent) ops and one file for each architecture.

Child returns a child of x in the dominator tree, or nil if there are none. The choice of first child is arbitrary but repeatable.

func (SparseTree) Sibling

func (t SparseTree) Sibling(x *Block) *Block

Sibling returns a sibling of x in the dominator tree (i.e., a node with the same immediate dominator) or nil if there are no remaining siblings in the arbitrary but repeatable order chosen. Because the Child-Sibling order is used to assign entry and exit numbers in the treewalk, those numbers are also consistent with this order (i.e., Sibling(x) has entry number larger than x's exit number).

type SparseTreeHelper

type SparseTreeHelper struct {
	Sdom   []SparseTreeNode // indexed by block.ID
	Po     []*Block         // exported data; the blocks, in a post-order

func (*SparseTreeHelper) NewTree

func (h *SparseTreeHelper) NewTree() *SparseTreeMap

type SparseTreeMap

type SparseTreeMap RBTint32

A SparseTreeMap encodes a subset of nodes within a tree used for sparse-ancestor queries.

Combined with a SparseTreeHelper, this supports an Insert to add a tree node to the set and a Find operation to locate the nearest tree ancestor of a given node such that the ancestor is also in the set.

Given a set of blocks {B1, B2, B3} within the dominator tree, established by stm.Insert()ing B1, B2, B3, etc, a query at block B (performed with stm.Find(stm, B, adjust, helper)) will return the member of the set that is the nearest strict ancestor of B within the dominator tree, or nil if none exists. The expected complexity of this operation is the log of the size the set, given certain assumptions about sparsity (the log complexity could be guaranteed with additional data structures whose constant- factor overhead has not yet been justified.)

The adjust parameter allows positioning of the insertion and lookup points within a block -- one of AdjustBefore, AdjustWithin, AdjustAfter, where lookups at AdjustWithin can find insertions at AdjustBefore in the same block, and lookups at AdjustAfter can find insertions at either AdjustBefore or AdjustWithin in the same block. (Note that this assumes a gappy numbering such that exit number or exit number is separated from its nearest neighbor by at least 3).

The Sparse Tree lookup algorithm is described by Paul F. Dietz. Maintaining order in a linked list. In Proceedings of the Fourteenth Annual ACM Symposium on Theory of Computing, pages 122–127, May 1982. and by Ben Wegbreit. Faster retrieval from context trees. Communications of the ACM, 19(9):526–529, September 1976.

func (*SparseTreeMap) Find

func (m *SparseTreeMap) Find(b *Block, adjust int32, helper *SparseTreeHelper) interface{}

Find returns the definition visible from block b, or nil if none can be found. Adjust indicates where the block should be searched. AdjustBefore searches before the phi functions of b. AdjustWithin searches starting at the phi functions of b. AdjustAfter searches starting at the exit from the block, including normal within-block definitions.

Note that Finds are properly nested with Inserts: m.Insert(b, a) followed by m.Find(b, a) will not return the result of the insert, but m.Insert(b, AdjustBefore) followed by m.Find(b, AdjustWithin) will.

Another way to think of this is that Find searches for inputs, Insert defines outputs.

func (*SparseTreeMap) Insert

func (m *SparseTreeMap) Insert(b *Block, adjust int32, x interface{}, helper *SparseTreeHelper)

Insert creates a definition within b with data x. adjust indicates where in the block should be inserted: AdjustBefore means defined at a phi function (visible Within or After in the same block) AdjustWithin means defined within the block (visible After in the same block) AdjustAfter means after the block (visible within child blocks)

	ID ID

	// The operation that computes this value. See op.go.
	Op Op

	// The type of this value. Normally this will be a Go type, but there
	// are a few other pseudo-types, see ../types/type.go.
	Type *types.Type

	// Auxiliary info for this value. The type of this information depends on the opcode and type.
	// AuxInt is used for integer values, Aux is used for other values.
	// Floats are stored in AuxInt using math.Float64bits(f).
	// Unused portions of AuxInt are filled by sign-extending the used portion,
	// even if the represented value is unsigned.
	// Users of AuxInt which interpret AuxInt as unsigned (e.g. shifts) must be careful.
	// Use Value.AuxUnsigned to get the zero-extended value of AuxInt.

	Aux    interface{}

	// Arguments of this value
	Args []*Value

	// Containing basic block
	Block *Block

	// Source position

	// nor a slot on Go stack, and the generation of this value is delayed to its use time.
	OnWasmStack bool
