compiler/liftdestructors

  Source   Edit

This module implements lifting for type-bound operations (=sink, =, =destroy, =deepCopy).

Procs

proc boolLit(g: ModuleGraph; info: TLineInfo; value: bool): PNode {....raises: [
    KeyError, Exception, ValueError, OSError, IOError, ERecoverableError], tags: [
    ReadDirEffect, RootEffect, WriteIOEffect, ReadIOEffect, ReadEnvEffect].}
  Source   Edit
proc createTypeBoundOps(g: ModuleGraph; c: PContext; orig: PType;
                        info: TLineInfo; idgen: IdGenerator) {....raises: [
    Exception, KeyError, ValueError, OSError, IOError, ERecoverableError], tags: [
    RootEffect, ReadDirEffect, WriteIOEffect, ReadIOEffect, ReadEnvEffect].}
In the semantic pass this is called in strategic places to ensure we lift assignment, destructors and moves properly. The later 'injectdestructors' pass depends on it.   Source   Edit
proc cyclicType(t: PType): bool {....raises: [Exception], tags: [RootEffect].}

                i: PNode): PNode {....raises: [], tags: [].}

    KeyError, Exception, ValueError, OSError, IOError, ERecoverableError], tags: [
    ReadDirEffect, RootEffect, WriteIOEffect, ReadIOEffect, ReadEnvEffect].}
