Module machine

Global machine state as well as implementation of the interpreter engine Machine trait.

Structs

• AllocExtra
  Extra per-allocation data
• FrameExtra
  Extra data stored with each stack frame
• MiriMachine
  The machine itself.
• PrimitiveLayouts
  Precomputed layouts of primitive types

Enums

• MiriMemoryKind
  Extra memory kinds
• Provenance
  Pointer provenance.
• ProvenanceExtra
  The “extra” information a pointer has over a regular AllocId.

Constants

• ADDRS_PER_ANON_GLOBAL 🔒
  Each anonymous global (constant, vtable, function pointer, …) has multiple addresses, but only this many. Since const allocations are never deallocated, choosing a new AllocId and thus base address for each evaluation would produce unbounded memory usage.
• SIGRTMAX
  Last real-time signal. signal(7) says it must be between 32 and 64 and specifies SIGRTMAX - SIGRTMIN >= 8 (which is the value of _POSIX_RTSIG_MAX)
• SIGRTMIN
  First real-time signal. signal(7) says this must be between 32 and 64 and specifies 34 or 35 as typical values.

Traits

• MiriInterpCxExt
  A little trait that’s useful to be inherited by extension traits.

Type Aliases

• MemoryKind
• MiriInterpCx
  A rustc InterpCx for Miri.
