Standard ML of New Jersey
Version 110.30, November 4, 2000

---

Summary:

• Port to ppc Linux (thanks to Carl Pulley).

• support for fsqrt, fptan, fcos, fsin.

• Several CM and CMB changes.

• Some critical bug fixes

---

Bug fixes

• 1514. sockets c-library broken

• 1582. SysErr exception connecting to socket

---

Back ends

x86

All back ends now directly generate the sqrt instruction, and the Intel x86 also generate the trig instructions to implement sine, cosine, and tangent.

The ICFP00, PCLubIN entry shows a significant improvement as a result (most of it coming from fsqrt).

CM

Changes to scripts

• "ml-build" for generating standalone programs
• "ml-makedepend" (new!) for generating Makefile dependencies (not generally required but some project might want them)
• "sml" - the main driver script for running SML/NJ.

All these scripts now accept more CM-related command-line options.

ml-build is faster and cleverer in avoiding unnecessary work.

Other Changes

Type of CM.mk_standalone has changed.

All user-visible changes to CM (including the above-mentioned scripts) are documented in the CM manual. Some errors and omissions have been corrected as well.

Bug fixes to CM's internals (e.g., missing or repeated error messages).

Pickling/Unpickling improvements result in faster autoloading and reduce resident memory size.

---

CMB

Conditional compilation within the "init library". (One can now use "ifdef" and "ifndef" guards in init.cmi. This is documented in the long comment at the beginning of that file (src/system/smlnj/init/init.cmi).)

---

Basis Library

Added SMLofNJ.SysInfo.getHeapSuffix (for use by "ml-build").
