i.e. put the extensions where they need to be, and delete
ice-9-debugger-extensions.scm.
* doc/ref/api-debug.texi (Single Stepping through a Procedure's Code):
Change mentions of (ice-9 debugging ice-9-debugger-extensions)
module to whatever is appropriate now (or just remove them).
* module/Makefile.am (NOCOMP_SOURCES): Remove
ice-9-debugger-extensions.scm.
* module/ice-9/debugger.scm (debug-trap): Move here from
ice-9-debugger-extensions.scm.
* module/ice-9/debugger/command-loop.scm ("continue", "finish",
"step", "next"): Move here from ice-9-debugger-extensions.scm.
* module/ice-9/debugger/commands.scm (assert-continuable, continue,
finish, step, next): Move here from ice-9-debugger-extensions.scm.
* module/ice-9/debugging/breakpoints.scm: Don't use
ice-9-debugger-extensions module.
* module/ice-9/debugging/ice-9-debugger-extensions.scm: Removed.
* module/ice-9/debugging/trace.scm, module/ice-9/debugging/traps.scm:
Remove more old version code.
* module/ice-9/debugging/traps.scm (guile-trap-features): Hardcoded as
'(tweaking).
* module/ice-9/boot-9.scm (default-pre-unwind-handler): Rename from
default-lazy-handler.
(pre-unwind-handler-dispatch): Rename from lazy-hadler-dispatch.
(error-catching-loop): Adjust caller.
* module/system/repl/repl.scm (default-pre-unwind-handler): Remove this
definition, in favor of the default one in boot-9.
(default-catch-handler): Don't do a vm-backtrace, as we will soon be
relying on core machinery to do that for us.
(call-with-backtrace): Start a new stack for the thunk.
(with-backtrace): Macro version of call-with-backtrace.
(start-repl): Use with-backtrace for brevity. Start a stack with #t as
the tag instead of repl-eval, because all traces of repl-eval are gone
after it does a tail-call.
* module/ice-9/debugger.scm:
* module/ice-9/debugging/traps.scm:
* module/ice-9/stack-catch.scm: Adapt to s/lazy/pre-unwind/ in
boot-9.scm.
Moved ice-9/ and oop/ under module/, with the idea being that we have
only scheme under module/. Adjusted configure.in and Makefile.am
appropriately. Put oop/ at the end of the compilation order.
