data ModGuts

A ModGuts is carried through the compiler, accumulating stuff as it goes There is only one ModGuts at any time, the one for the module being compiled right now. Once it is compiled, a ModIface and ModDetails are extracted and the ModGuts is discarded.

data CgGuts

A restricted form of ModGuts for code generation purposes

Constructors

CgGuts

Fields

• cg_module :: !Module

  Module being compiled

• cg_tycons :: [TyCon]

  Algebraic data types (including ones that started life as classes); generate constructors and info tables. Includes newtypes, just for the benefit of External Core

• cg_binds :: CoreProgram

  The tidied main bindings, including previously-implicit bindings for record and class selectors, and data constructor wrappers. But *not* data constructor workers; reason: we regard them as part of the code-gen of tycons

• cg_foreign :: !ForeignStubs

  Foreign export stubs

• cg_foreign_files :: ![(ForeignSrcLang, FilePath)]
• cg_dep_pkgs :: ![UnitId]

  Dependent packages, used to generate #includes for C code gen

• cg_hpc_info :: !HpcInfo

  Program coverage tick box information

• cg_modBreaks :: !(Maybe ModBreaks)

  Module breakpoints

• cg_spt_entries :: [SptEntry]

  Static pointer table entries for static forms defined in the module. See Note [Grand plan for static forms] in GHC.Iface.Tidy.StaticPtrTable
