A 1-liner `Hello, World`! This example can be found in +`examples/A_helloWorld.smp`. + + +Let's break it down. + +- `sys`: is Just A Variable Name.

Every Simple program now starts + with the `sys` variable in-scope. `sys` itself is a normal `struct` + and is defined in `src/main/smp/sys.smp`. +- `sys.io.p`: lookup the `io` field in `sys` struct, which yields the `sys.io` + struct; then a lookup of `p` (short for "print") in the `sys.io` struct. + This returns a function. +- `p("Hello, World!")`: call the function just loaded from the `p` field, with + `"Hello, World!"` as a string argument. +- `"Hello, World!"`: New syntax that yields a constant array of `u8` (chars). + The array is otherwise a normal range-checked array, with a leading `#` + length field. The array backing data eventually ends up in the *constant + pool*, and from there in an ELF file's RODATA section. + + +Chapter 11's lazy memory partitioning continues here: the parser carries one +`$mem`, and BulkMemPhi/MemPhi discover field aliases during optimization. +Allocations consume a partial MemMerge and produce `{ptr, $mem}`; calls carry +whole memory. The loop Load search follows every arm of a memory merge, so +BrainFuck's invariant program length folds out of its main loop. + +You can also read [this chapter](https://github.com/SeaOfNodes/Simple/tree/linear-chapter22) 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-chapter21...linear-chapter22) it to the previous chapter. + + +Here is the [complete language grammar](22-grammar.md) for this chapter. + +## Nested Types and Static Fields + +Simple now supports nested types - this is a name-space only change, so no new +semantics - just the ability to nest type definitions. + +```java +struct Outer { + struct Inner { + int in; + flt pi = 3.14; + }; + int out; +}; +``` + +Any final field set in the declaration (as opposed to the constructor) is +automatically a "static" field - it is final for all instances, and does not +need to be stored in each instance. Instead one copy is kept in a global +space (not really a *class* object yet) and loaded from there. + +In this example: + +- Instances of the `Outer` struct have a single `int` field `out`. +- Instances of the `Inner` struct have a single `int` field `in`. +- There exists an `Outer.Inner.pi` field in a global space with value `3.14`. + +The `sys` struct is another example, with nested `libc` and `io` structs at +least. All the fields in these structs are all final, hence static. + + + +## FFI and I/O Calls + +We can now call external / FFI functions, and they are declared like any other +variable except being assigned "C". Here is the binding for the libc `write` +call: + +`{ i32 fd, i64 buf, u32 len -> u32 } write = "C";` + +Any final variable assigned as "C" will be considered defined externally. The +syntax of this might change slightly to avoid ambiguity with assigning the same +"C" string. + +There is no linker support for getting the correct signature or namespace; the +name `write` has to be unique when linking. + + +## Auto-Import and the "sys." namespace + +The `sys` struct includes `libc` bindings, and any default library code +including e.g. printing support and collections. As of this chapter it +includes minimal libc bindings and an easy print. This excerpt shows the +parts used above: + +```java +// top-level default import +struct sys { + // libc bindings + /** https://www.man7.org/linux/man-pages/man2/<libc call>.2.html */ + struct libc { + // fd buf len -> len + { i32 i64 u32 -> u32 } write = "C"; + // addr len prot flags fd off -> void* + { i64 i64 i32 i32 i32 i32 -> i64 } mmap = "C"; + // mmap flags + i32 PROT_EXEC = 4; + i32 PROT_READ = 1; + i32 PROT_WRITE= 2; + i32 PROT_NONE = 0; + i32 MAP_PRIVATE = 2; + i32 MAP_ANON = 32; + }; + struct io { + val p = { u8[~] str -> + i64 ptr = str; // cast array base to i64 + return sys.libc.write(1,ptr,str#); + }; + }; +}; +``` + +The `sys` import itself is Just Another `struct` like any other struct; it has +fields and assignments and types declared internally. Note that these +assignments are all final and in the struct declaration, hence these are all +*static* fields. + + +## Casting a Pointer to an `i64` + +You can now cast a pointer to an i64, although not the other way around. +`i64 ptr = str; // cast array base to i64` + +For arrays, this cast is to the array *base* skipping the `#` length field, and +is suitable for passing to external "C" calls. For structs, this is just the +struct base. This is used to pass a length-checked Simple array to the libc +`write` call in the above `sys.io.p` function. + + +## Arrays of Constants and Constant Arrays + +The Simple type system now supports the notion of a "constant array" - an array +of fixed constants, stored in the ELF file in the RODATA section. Currently we +only support strings at the parser level: `"Hello, World!"` makes a `u8[13]` +array containing 13 ASCII bytes; like all arrays it has a length and will be +range-checked at some point. + +A constant version of a non-constant array can be assigned using the `u8[~]` +syntax. + +```java +// Make a mutable array of ints +int N=4; +i32[] is = new i32[N]; +// Mutate the array +for( int i=0; i<N; i++ ) + is[i] = i*i; +// Function "sum" can read but not write the array +val sum = { i32[~] nums -> // Notice the [~] signature marking nums as immutable + int sum = 0; + for( int i=0; i<nums#; i++ ) + sum += nums[i]; + return sum; +}; +return sum(is); +``` + +Note that this affects the deep contents of the array and not the array +variable itself. + +## Quote Characters + +The form ``` `0` ``` makes a `u8` value with the ASCII character `0`. + +## Continuous Improvement + +Executing larger programs exposes mistakes that graph-only tests can miss. +During the original development of this chapter, these included x86 instruction +encodings and flag clobbers, scheduling around loop backedges and memory stores, +and stale dominator depths during inlining. Corrections are being moved into the +earliest applicable chapters so readers can build on working compiler snapshots. +Native tests check both output and process exit status; emulator tests check the +returned values and memory as well as successful execution. + +## RegAlloc improvements: better color bias + +Chapter 21 introduced conservative copy coalescing. Here we improve the register +preferences used when related live ranges cannot coalesce. A copy chain can take +an already assigned register even at its terminal definition; a loop Phi prefers +its backedge's register, avoiding a move on each iteration when possible. + +When no live range is trivially colorable, cheap values make better spill +candidates. We favor a cloneable definition with distant or multiple uses over +one already adjacent to its only use, then callee-save values whose long spans +are cheap to split. Register order breaks ties between callee saves. These +are small preferences, not a general cost model. Grouping popular values by +register class is left for Chapter 23, cold loop splits for 24, and area/cost +ranking for 25. + +Rows are fixed test cohorts; columns are compiler chapters. Each cell gives +**Ops / RA / X**: executed ARM+RISC-V instructions, the subset emitted for +allocator copies/rematerializations, and x86's loop-weighted split-move estimate. +**Cases D / X** counts measured dynamic program/target cases and x86 compilations; +membership and inputs stay fixed across columns. Native-library work is excluded. +Chapter 20 has no encoder, hence no dynamic counts. Lower is better within each +metric; see the [measurement details](../regalloc-spills.md) for coverage. + +<!-- spill-matrix:start --> +| Test cohort | Cases D / X | Ch 20: Ops / RA / X | Ch 21: Ops /
