(int x) is no longer emitted by the cogen.
...
assembler handles (int x) and fixnums similarly.

Pretty-printed gensyms:
...
* print-gensym now accepts the symbol "pretty" as a valid
argument.
* The writer prints #:pretty-name if the print-gensym value
is |pretty|.
* The reader accepts #:id as a valid syntax. The result is
a fresh gensym with id as a pretty-name.
2006-12-25 11:33:03 +03:00

Tokenize now recognizes gensym syntax:
...
#{id0} => a fresh gensym with pretty-string id0
#{id0 id1} => an interned gensym with pretty-string id0
and unique-string id1.
id0 and id1 can have any identifier syntax including bar-quoted ids.
any number of whitespaces can be placed around id0 and id1.

...
when an interrupt occurs.

Actually, the profiling times show that memory-based tests can be
...
performed at around 3 secs per 1 billion checks (about 6 times
slower than register-based counters).
2006-12-21 16:32:45 +03:00
67a850e712
Profiling timing shows that we can do interrupt checks with cost:
...
* about 2.0 secs per 1 billion checks if the counter is kept in memory
* about 0.5 secs per 1 billion checks if the counter is kept in register.
2006-12-21 16:22:07 +03:00
