Abdulaziz Ghuloum ffc5ef557c (int x) is no longer emitted by the cogen.
assembler handles (int x) and fixnums similarly.

Abdulaziz Ghuloum cfe69af8f8 BUGS file added to keep track of some pending bugs. 2006-12-25 11:38:18 +03:00
Abdulaziz Ghuloum f25cc3cb67 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
Abdulaziz Ghuloum e7d0a0a1cc 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.

Abdulaziz Ghuloum e69f0a5c80 * Assembler-output suppresses printing the closure-size; it prints

Abdulaziz Ghuloum efae97a6e0 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
Abdulaziz Ghuloum 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
Abdulaziz Ghuloum 5615b03879 * Input/output ports are closed when the last reference to them is
