Abdulaziz Ghuloum 1f2b250ed9 fixed a bug in (not) handling variable-size frames in ikarus-exec. 2010-01-26 07:35:09 +03:00
Abdulaziz Ghuloum 943a72f01f fixed a bug in the register allocator that was rewriting
mov8 mem1 -> mem2
    mov mem1 -> reg
    mov8 reg -> mem2
instead of
    mov8 mem1 reg
    mov reg mem2
which causes unaligned and invalid memory access when the
address mem1 is at a page boundary and the next page is

Abdulaziz Ghuloum 64aca7c80b one more fix for 64-bit jumps and calls. Some conditional jumps
required cross-code offsets which are now eliminated.

Abdulaziz Ghuloum 820eb7dcb9 Fixed the ``relocation error'' that happens in 64-bit mode. What
used to be a relative jump from one code object to another is now
turned into a pc-relative jump, where the jump targets are stored
somewhere at the bottom of the code that performs the jump:

old code sequence:

        call-relative (Ltarget - L0)
    L0: ...

new code sequence:

        call-pc-relative (L1 - L0)
    L0: ...
    L1: <8-byte Ltarget>

Abdulaziz Ghuloum d03fbfe4ef fixed bug in expanding macros in internal definitions which were

Abdulaziz Ghuloum b586d2e21a some asserion violations in the reader are converted to &lexicals so
that the repl displays them properly.  E.g., 
(read (open-string-input-port "#!r6rs |foo|")) shows an &assertion,
but typing #!r6rs |foo| at the repl causes the repl to reset without
a message.

Abdulaziz Ghuloum fe88c7bd0d fixed incorrect setting of IKARUS_LIBRARY_PATH. 2009-07-06 13:20:09 +03:00
Abdulaziz Ghuloum acbd00c356 fixed a bug in expanding macros in definition context where the
scope would get messed up when the macro call appears inside
let/letrec-syntax.  Basically, in the following example,

(let-syntax ([id-macro (syntax-rules () [(_ x) x])])
  (let () 
    (define (foo) (display "not ok\n")) 
    (let-syntax ([foo (syntax-rules () [(_) (display "ok\n")])])
      (id-macro (foo)))))

the call to (id-macro) would make (foo) refer to the foo in the
internal-definition context (the not ok one) instead of the
let-syntax one.

On the plus side, macro expansion is now half a second faster!
