Abdulaziz Ghuloum 85d09cbc1c fxarithmetic-shift-left now detects overflows properly. 2008-03-18 00:49:24 -04:00
Abdulaziz Ghuloum 3811d0a4c2 Loops with a single free variable no longer allocate a closure. 2008-02-11 22:18:32 -05:00
Abdulaziz Ghuloum e1d9e72983 some compiler cleanup 2008-02-11 09:29:59 -05:00
Abdulaziz Ghuloum f6e5e4d5b4 Added -m32 to CFLAGS/LDFLAGS, updated copyright dates and version no. 2008-01-29 00:34:34 -05:00
Abdulaziz Ghuloum df1cef98be - Added primop for *. 2008-01-19 16:11:00 -05:00
Abdulaziz Ghuloum 7a2ac14f5a Eliminated frame-pointer adjustment around calls if the adjustment
is 0.  Previously, you'd get 
    addl 0, fpr
    <stuff>
    subl 0, fpr
which are useless.

Abdulaziz Ghuloum c15876aebe Abstracted the construction of call frames and automated the padding
process.  The compiler no longer has hardcoded null bytes inserted
into the code streams.

Abdulaziz Ghuloum 0db7d1d6d0 Identified places where a hard-coded number of null bytes are
manually inserted into the code stream to ensure proper offsets.
These need to be removed ASAP.  Also, abstracted the values of three
constants that were hardcoded.

Abdulaziz Ghuloum 50e2478d06 removed some hard-coded constants of pcb-offsets. 2008-01-01 23:07:41 -05:00
Abdulaziz Ghuloum f44b9285c7 small bug fix in assembler for code like (movl reg (disp reg reg)) 2007-12-31 03:02:12 -05:00
Abdulaziz Ghuloum eb30e7ab58 * Eliminates a jump-to-jump case in "flatten-code". 2007-11-21 05:31:01 -05:00
Abdulaziz Ghuloum 37aab027da Added an optimization that removes self-references from fix-bound
closures.

Abdulaziz Ghuloum efa2f0ef43 * '#!eof no longer signals an assembler error
- bug reported by micheal adams in person.

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.
