Functions

Const assemble

assemble(dim: number, tpl: Template, syms: string, ret?: string, opJoin?: string, pre?: string, post?: string, strided?: boolean): string[]

- Defined in packages/vectors/src/internal/codegen.ts:114
Code generator for loop-unrolled vector operations. Takes a vector size dim, a code template function tpl and an array of symbol names participating in the template. For each symbol, creates iterator of index lookups (e.g. a[0] or a[ia+k*sa]), forms them into tuples and passes them to template to generate code and joins generated result with opJoin separator (default: "").
If the optional ret arg is not null (default "a"), appends a return statement to the result array, using ret as return value. Returns array of source code lines.
The optional pre and post strings can be used to wrap the generated code. post will be injected before the generated return statement (if not suppressed).
Parameters
- dim: number
  -
- tpl: Template
  -
- syms: string
  -
- Default value ret: string = "a"
  -
- Default value opJoin: string = ""
  -
- Default value pre: string = ""

- Default value strided: boolean = false

Returns string[]
