lang_registry.c (2394B)

      1 /* Language frontend registry.
      2  *
      3  * This file is the *only* place in libkit that checks
      4  * KIT_LANG_*_ENABLED. It runs during compiler construction and wires
      5  * each compiled-in frontend's vtable into c->frontends[] so the public
      6  * compile/pipeline paths can dispatch by KitLanguage without any
      7  * host-side bootstrap.
      8  *
      9  * The asm frontend lives inside the codegen substrate, but automatic
     10  * registration is gated by KIT_LANG_ASM_ENABLED.
     11  *
     12  * Third parties may still call kit_register_frontend() to install or
     13  * override any slot after construction; that public API is unchanged.
