For explanation, see comments and text in the new file
libguile/measure-hwm.scm.
* .gitignore: Add libguile/stack-limit-calibration.scm.
* check-guile.in: Load libguile/stack-limit-calibration.scm.
* configure.in: Add AC_CONFIG_FILES to generate test-use-srfi from
test-use-srfi.in.
* libguile/Makefile.am (TESTS, TESTS_ENVIRONMENT,
stack-limit-calibration.scm): New targets, so that `make check'
calibrates the stack limit before running the Guile test suite.
* libguile/measure-hwm.scm: New file, calibrates stack limit for `make
check'.
* libguile/stackchk.c (scm_sys_get_stack_size): New primitive.
* libguile/stackchk.h (scm_sys_get_stack_size): New primitive
(declaration).
* test-suite/standalone/test-use-srfi: Renamed test-use-srfi.in, so
that ./configure can fill in variables in it.
* test-suite/standalone/test-use-srfi.in: Load
libguile/stack-limit-calibration.scm.
* configure.in: Update stack direction test to be like that in
Autoconf _AC_LIBOBJ_ALLOCA and Gnulib; specifically in involving a
function calling itself.
directly, and only if GUILE_I was defined by the configure step.
(scm_log, scm_log10, scm_exp, scm_sqrt): Use SCM_COMPLEX_VALUE
code only if SCM_COMPLEX_VALUE is defined.
* configure.in (--without-64-calls): Use AC_MSG_CHECKING and
AC_MSG_RESULT instead of just echo.
(GUILE_I): New programs to try using _Complex_I or 1.0fi for the
imaginary unit.
* threads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp() and
scm_ia64_register_backing_store_base() instead of Linux-specific
implementations.
* gc.h (scm_ia64_register_backing_store_base, scm_ia64_ar_bsp):
New declarations.
* gc.c (__libc_ia64_register_backing_store_base): Declaration
removed.
(scm_ia64_register_backing_store_base, scm_ia64_ar_bsp): New, with
implementations for Linux and HP-UX.
* coop-pthreads.c (SCM_MARK_BACKING_STORE): Use scm_ia64_ar_bsp()
and scm_ia64_register_backing_store_base() instead of
Linux-specific implementations.
* continuations.h (__libc_ia64_register_backing_store_base):
Declaration removed.
(scm_t_contregs): New "fresh" field.
* continuations.c (ia64_getcontext): Removed.
(scm_make_continuation): Use continuation fresh field instead of
interpreting getcontext return values (which isn't portable). Use
scm_ia64_ar_bsp() and scm_ia64_register_backing_store_base()
instead of Linux-specific implementations.
(copy_stack_and_call): Use scm_ia64_register_backing_store_base()
instead of Linux-specific implementation.
* _scm.h (__ia64__): Also detect __ia64.
* debugging/trc.scm: New file.
* debugging/traps.scm: New file.
* debugging/trace.scm: New file.
* debugging/steps.scm: New file.
* debugging/load-hooks.scm: New file.
* debugging/ice-9-debugger-extensions.scm: New file.
* debugging/example-fns.scm: New file.
* debugging/breakpoints.scm: New file.
* debugging/Makefile.am: New.
* Makefile.am (SUBDIRS): Add debugging.
AC_CHECK_LIB instead. Do not subst LTDLINCL and LIBLTDL. Do not
add "-DLIBLTDL_DLL_IMPORT" on MINGW32.
* Makefile.am (SUBDIRS): Removed libltdl.
* README: Talk about required external packages.
* autogen.sh: Do not call libtoolize.
AC_LIB_LTDL.
(AC_CONFIG_SUBDIRS): Added libltdl.
(DLPREOPEN, LTDLINC, LIBLTDL): Moved AC_SUBST near other libtool
stuff. Also subst LTDLINC instead of INCLTDL.
(AC_CONFIG_FILES): Removed libguile-ltdl/Makefile and
libguile-ltdl/upstream/Makefile.
* Makefile.am (SUBDIRS): Replaced libguile-ltdl with libltdl.
