* libguile/__scm.h (SCM_ALIGNED): New macro.
* libguile/_scm.h: Include "libguile/strings.h", to make the
string/stringbuf-related constants visible to snarffed code.
* libguile/snarf.h (SCM_SUPPORT_STATIC_ALLOCATION): New macro.
(SCM_SYMBOL, SCM_GLOBAL_SYMBOL)[SCM_SUPPORT_STATIC_ALLOCATION]: New
alternative versions of these macros with support for (almost) static
allocation via the use of `string->symbol'.
(SCM_IMMUTABLE_DOUBLE_CELL, SCM_IMMUTABLE_STRINGBUF,
SCM_IMMUTABLE_STRING): New macros.
* libguile/tags.h (SCM)[SCM_DEBUG_TYPING_STRICTNESS==1]: Use a pointer
type that is compatible with other pointer types, to avoid potential
violation of strict aliasing rules.
forever, and are known to conflict on some platforms with that
provided by <errno.h>, which we include unconditionally. If
<errno.h> doesn't provide a errno declaration, what is the point
of it?
* 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.
(SCM_NONREC_CRITICAL_SECTION_START,
SCM_NONREC_CRITICAL_SECTION_END, SCM_REC_CRITICAL_SECTION_START,
SCM_REC_CRITICAL_SECTION_END): New macros.
(SCM_CRITICAL_SECTION_START/END): Defined here.
* eval.c: Insert SOURCE_SECTION_START / SOURCE_SECTION_END around
the three calls to scm_m_expand_body.
* gc.h: #include "libguile/pthread-threads.h";
(SCM_FREELIST_CREATE, SCM_FREELIST_LOC): New macros.
* gc.c (scm_i_freelist, scm_i_freelist2): Defined to be of type
scm_t_key;
* gc.c, gc-freelist.c, inline.h: Use SCM_FREELIST_LOC for freelist
access.
* gc-freelist.c (scm_gc_init_freelist): Create freelist keys.
* gc-freelist.c, threads.c (really_launch): Use
SCM_FREELIST_CREATE.
* gc-malloc.c (scm_realloc, scm_gc_register_collectable_memory):
* gc.c (scm_i_expensive_validation_check, scm_gc,
scm_gc_for_newcell): Put threads to sleep before doing GC-related
heap administration so that those pieces of code are executed
single-threaded. We might consider rewriting these code sections
in terms of a "call_gc_code_singly_threaded" construct instead of
calling the pair of scm_i_thread_put_to_sleep () and
scm_i_thread_wake_up (). Also, we would want to have as many of
these sections eleminated.
* init.c (scm_init_guile_1): Call scm_threads_prehistory.
* inline.h: #include "libguile/threads.h"
* pthread-threads.h: Macros now conform more closely to the
pthreads interface. Some of them now take a second argument.
* threads.c, threads.h: Many changes.
* configure.in: Temporarily replaced "copt" threads option with new
option "pthreads".
(USE_PTHREAD_THREADS): Define if pthreads configured.
* *.c: add space after commas everywhere.
* *.c: use SCM_VECTOR_SET everywhere, where a vector is written.
Document cases where SCM_WRITABLE_VELTS() is used.
* vectors.h (SCM_VELTS): prepare for write barrier, and let
SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.
* autogen.sh (mscripts): find and check version number of
autoconf. Complain if 2.53 is not found.
* error.c, net_db.c, putenv.c, stime.c: Removed declaration of
errno variable (can be a macro on some systems, for example when
using linux libc with threads).
* error.c, filesys.c, gc.c, ioext.c, iselect.c, net_db.c, ports.c,
posix.c, print.c, putenv.c, scmsigs.c, script.c, simpos.c, smob.c,
socket.c, srcprop.c, stime.c, strop.c, unif.c, vports.c: Added
#include <errno.h> in these 20 out of 100 files.
and we don't want that.
(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)
* configure.in: use AC_SYS_RESTARTABLE_SYSCALLS instead of
testing for SA_RESTART.
1999-09-18 Gary Houston <ghouston@freewire.co.uk>
* _scm.h, scmsigs.c: replace HAVE_RESTARTS with
HAVE_RESTARTABLE_SYSCALLS.
* _scm.h: if HAVE_RESTARTS is defined then don't use a SYSCALL
loop.
* posix.c (scm_uname): interpret only negative values as an error.
Solaris normally returns a positive value.
* script.c (scm_compile_shell_switches): if we are not going into
an interactive repl, set scm_mask_ints to zero so that asyncs can
run.
* simpos.c (scm_system): don't ignore/unignore signals around
the "system" call.
* posix.c (scm_open_pipe): don't ignore/unignore signals around
the "popen" call.
* init.c (scm_boot_guile_1): don't call scm_init_signals, it's
done in boot-9.scm instead.
* scmsigs.c, async.c: Major rewriting of signal handling code.
(scm_sigaction): new procedure.
(scm_sleep): don't wrap sleep in SCM_SYSCALL, it would mess up the
timing.
(scm_raise): return unspecified, throw error on failure.
* boot-9.scm: signal-handler, alarm-thunk: removed.
don't define ticks-interrupt etc.
top-repl: install signal handlers for SIGINT, SIGFPE, SIGSEGV, SIGBUS
during call to scm-style-repl.
* acconfig.h: mention HAVE_RESTARTS.
* configure.in: check for sigaction and restartable system calls.
* guile-snarf.sh: New file.
* Makefile.in (inner_h_files): Added snarf.h
(ancillary, install, uninstall, distclean): Added actions for
guile-snarf.
(.c.x): Use guile-snarf.
(guile-snarf): New rule, to produce guile-snarf from guile-snarf.sh.
(gen_c_files): Note that these depend on guile-snarf.
* _scm.h: Removed the snarfing macros (SCM_PROC, etc). They are
now in "snarf.h". Added #include "snarf.h" to get them.
* configure.in: Added guile-snarf to AC_OUTPUT
* libguile.h: Added #include "snarf.h".
