Initial cut at writing COERCE-TO-COMPILED-PROCEDURE in Scheme.  The
next change will be to make the compiler generate calls to this
procedure rather than the primitive COERCE-TO-COMPILED-PROCEDURE,
which should result in both faster generation and invocation of
trampolines.

Eventually we might make the linker use this code too.

The code is a bit hairy and needs special initialization, hence the
changes in make.scm.

28 years agoAdded new stack frame type for preservation frames (restore-regs).
Stephen Adams [Fri, 26 Jul 1996 00:36:11 +0000 (00:36 +0000)]
Added new stack frame type for preservation frames (restore-regs).
Added a debugging-info method.

Changed the illegal-arg error handler for primitive procedures to
avoid using retry restarts when the primitive signalled a type or
range error when called from compiled code.  This is necessary because
the compiler assumes that if it calls a primitive just to raise an
error then teh primitive will not return.  This assumption allows type
inference to eliminate furthur checks.

In order to stop the debugger returning a value, the primitive should
be called `indirectly' via another compiler procedure which refuses to
return.  I.e instead of compiling the error CAR operation as
INVOKE:PRIMITIVE

  (#[primitive-procedure car] x)

call it like this:

  (signal-primitive-error '#[primitive-procedure car] x)
