                                WARNING

        This working version is believed to be stable, but
        we have not run our full regression-test suite.

Summary:

Details:

Basis:

• SMLofNJ.Susp is back.

CML

• Thread-safe version of structure Atom matches original signature and re-uses the original implementation. Moreover, since an mvar is used as a lock (instead of a separate server thread) to protect the global hashtable, it is now possible to create atoms even before RunCML.doit has started executing.

Library

• Moved source tree from smlnj-lib/TraceDebugProf to a new tools/TraceDebugProf.

NLFFI

• Handles access to signed and unsigned long long data.
• Handles long long function arguments and results (but so far only on the PowerPC).
• Some organizational cleanup of the library code.

ML-Yacc

• Fixed formatting bug that sometimes caused syntactically incorrect code from being formed.

Runtime

• Fixed bug in PC-sampling profiler.
• Fixed off-by-1 bug in ML_STRING macro (which caused the names of certain exceptions to be garbled).

Scripts

• Added an experimental heap2exec script (with a helper heap2asm script in the background). This is experimental and so far only works under Mac OS X.
• Made ml-build script slightly smarter. (One can now omit the 3rd argument -- which in this case is taken to be the same as the 1st argument without the extension.
• _run-sml now converts SMLNJ_HOME to a POSIX pathname on cygwin.

CM

Fixed its incorrect assumption about the PowerPC being little-endian. (PPC couldn be little-endian, but on the only supported platform -- Mac OS X -- it is big-endian.)

MLRISC

• Bugfixes in c-calls implementation.
