...
Eddington's suggestions and removed the record-name check for
non-generative records.

* Added port-mode and set-port-mode! primitives. A port mode is
...
either the symbol ikarus-mode or the symbol r6rs-mode.

* Added $flonum-sbe primop for extracting the signed-biased-exponent
...
of a flonum.

* open-coded $flround.

5d0f86377e
* Fixes bug 161923: Segfault on float ops
...
(I was trying to be too clever with optimizing the checks.)

* Added bytevector-ieee-single-ref and bytevector-ieee-single-set!
2007-11-08 22:56:14 -05:00

* Added bytevector-ieee-single-native-ref and bytevector-ieee-single-native-set!
2007-11-08 22:22:24 -05:00

* improved performance for fl+, fl-, fl*, fl/, fl=?, fl<?, fl<=?, fl>? and fl>=?
...
- results in
45% reduction in runtime for fpsum
43% reduction in runtime for fibfp
29% reduction in runtime for pnpoly
28% reduction in runtime for mbrot
- and
23% increase in compile time for nucleic
11% increase in compile time for ray
10% increase in compile time for fft

* bytevector-ieee-double-ref/set! now work
2007-11-07 04:54:54 -05:00
7dbce6e888
* Added bytevector-ieee-double-ref and bytevector-ieee-double-set!
...
(which does not yet support big endianness)
2007-11-07 01:26:38 -05:00

* Added bytevector-ieee-double-native-ref/set!
2007-11-06 21:08:52 -05:00
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.
2007-11-05 15:30:42 -05:00
6f576dc224
* Added license stubs to all *.ss and *.[ch] files.
