Work in progress on reimplementing the optimizer based on
...
Oscar Waddell's dissertation (chapter 4). The existing
optimizer in Ikarus is just a joke.

Loops with a single free variable no longer allocate a closure.

simple constants from being initialized properly.

SCC-letrec optimization is now online.

SCC-letrec kinda works now.

work yet.

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.

Ikarus can compile immediates in 64-bit mode.

It feels like I'm going through my compilers tutorial all over again!

64-bit fasl files can now be produced and read.

fasl-write now writes different fasl objects depending on the

architecture bitness.

Abstracted the construction of call frames and automated the padding
...
process. The compiler no longer has hardcoded null bytes inserted
into the code streams.
2008-01-02 07:01:45 -05:00
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.
2008-01-02 05:55:30 -05:00

New IO layer is installed. Still buggy in some area but can be used
...
for bootstrapping at least.

Added an optimization that removes self-references from fix-bound
...
closures.
2007-11-21 04:00:10 -05:00

either the symbol ikarus-mode or the symbol r6rs-mode.

* Global variables which are assigned (or complex) no longer have lexical
...
copy. All references and assignments to them goes through the
symbol value slot.

* libraries are now expanded to a special library-letrec* form.

* 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!
