- * Various C datatypes used in the run-time system. This is the
- * lowest-level include file, after ghcconfig.h and RtsConfig.h.
- *
- * This module should define types *only*, all beginning with "Stg".
- *
- * Specifically:
-
- StgInt8, 16, 32, 64
- StgWord8, 16, 32, 64
- StgChar, StgFloat, StgDouble
-
- ***** All the same size (i.e. sizeof(void *)): *****
- StgPtr Basic pointer type
- StgWord Unit of heap allocation
- StgInt Signed version of StgWord
- StgAddr Generic address type
-
- StgBool, StgVoid, StgClosurePtr, StgPtr, StgOffset,
- StgTSOPtr, StgForeignPtr, StgStackOffset, StgStackPtr,
- StgCode, StgArray, StgByteArray, StgStablePtr, StgFunPtr,
- StgUnion.
-
- * WARNING: Keep this file, MachDeps.h, and HsFFI.h in synch!
- *
- * NOTE: assumes #include "ghcconfig.h"
- *
- * Works with or without _POSIX_SOURCE.
