patch applied (hat): Show values of type IO as Abstract " IO" .

10 Oct '06

Tue Apr 23 03:02:19 PDT 2002 olaf * Show values of type IO as Abstract "IO". Values of type IO used to be of the form `hidden applied to lambda'. Showing Abstract IO instead is clearer (value of an abstract type) and does not contain less information. It is still possible to ask for the parent of Abstract IO.

patch applied (hat): Improved speed of writing new trace.
by Malcolm Wallace 10 Oct '06

Thu Apr 18 09:54:39 PDT 2002 olaf * Improved speed of writing new trace. Introduced buffer to defer updating (entering and result) and then do the updates in bulks. Improves Adjoxo from 30s to 24s. Independent of buffers size between 16 bytes and 128 Kbytes. Only worse for smaller buffers. Main effect is probably halfing of number of seek operations. Then added some update avoidance: Updating of result first tests (linear seach) if such an update is already in the buffer and then overwrites it in buffer. Improves Adjoxo further to 20s for small buffers (32-64 bytes). Larger buffers increase linear search unduly, although system time is still reduced further. Finally, make linear search through buffer backwards, because overwritten entry is most likely the most recently entered one. Improves Adjoxo further to 17.5s for buffers between 1KB and 4KB. Clearly similar to previous times for small buffers. Slight increase for larger buffers. M ./src/hatlib/hat-c.c -35 +92 M ./src/hatlib/hat-c.h +3

patch applied (hat): hat-stack now works with the new file format.

Thu Apr 18 08:09:02 PDT 2002 malcolm * hat-stack now works with the new file format. In artutils.c, the getResult() routine now follows the result pointer chain to the end. Also, readTraceAt() now correctly gets the result of every subexpression in an application. M ./src/hattools/artutils.c -90 +152 M ./src/hattools/hat-stack.c -2 +6

patch applied (hat): Extended/debugged new file format generation.
by Malcolm Wallace 10 Oct '06

10 Oct '06

Thu Apr 18 07:58:05 PDT 2002 olaf * Extended/debugged new file format generation. Now a call of "error" aborts correctly, recording the error message and the entry point in the trace. Corrected a bug in "fun" combinators, which caused wrong parents. Handle "undefined" specially, so that it yields a non-shared ConstDef with a proper parent. Thus following backwards from "undefined" with hat-trail is possible.

Thu Apr 18 04:34:58 PDT 2002 olaf * Extended/debugged new file format generation. Now ConstructorWFields is used to record data constructors that have fields. Here the list of labels is passed as an array to C. Recording of FieldUpdate corrected (HatCounter was incorrectly updated). Recoding of Int corrected (number was not in network order).

patch applied (hat): Move the _old_ include/art.h to src/hat/runtime. The old -T
by Malcolm Wallace 10 Oct '06

Wed Apr 17 02:24:56 PDT 2002 malcolm * Move the _old_ include/art.h to src/hat/runtime. The old -T transformation still uses the old file format, and this move should keep it in working order for the moment. A ./src/old/runtime/art.h
