Abdulaziz Ghuloum 37aab027da Added an optimization that removes self-references from fix-bound
closures.

Abdulaziz Ghuloum 5ce6ca4efb * Added bytevector-ieee-single-native-ref and bytevector-ieee-single-native-set! 2007-11-08 22:22:24 -05:00
Abdulaziz Ghuloum 1b103a4ab8 * bytevector-ieee-double-ref/set! now work 2007-11-07 04:54:54 -05:00
Abdulaziz Ghuloum 7dbce6e888 * Added bytevector-ieee-double-ref and bytevector-ieee-double-set!
(which does not yet support big endianness)

Abdulaziz Ghuloum 327e6e9371 * Fixed bug 160483: described as "incorrect number of arguments" reported as "not a function"
- The real reason was in the register allocator, where one live
    variable (the memmory size of the bytevector) was not marked live 
    across the call to do-overflow.  When the overflow returned, the 
    value of that variable (which was in the %ebx register) was
    trashed, leading to an incorrect bump in the allocation pointer.
  - Note to self, never blame anything on cache coherency again!

Abdulaziz Ghuloum 037351e27e * Two minor non-optimizations for $event-check and $stack-overflow-check
* If a procedure does not make non-tail calls, stack-overflow is eliminated.
  * If a procedure does not make any calls (leaf routine), then event-check 
    is eliminated as well.
  (total savings: about 10% reduction in boot-file size)

Abdulaziz Ghuloum 8e85c3303b * Switched order of two compiler passes: specify-representation and
insert-stack-overflow-check.  This will make it easier to remove 
   unnecessary stack checks and to add some that we *may* be
   missing.
* Added a $stack-overflow-check primitive that takes care of checking
  and calling ikrt_stack_overflow if we did detect an overflow.
