2012-06-13Use a simple struct to implement compile time checks for the Lisp_Object typeAndreas Schwab1-16/+1
* configure.in: Rename --enable-use-lisp-union-type to --enable-check-lisp-object-type and define CHECK_LISP_OBJECT_TYPE instead of USE_LISP_UNION_TYPE. * admin/make-emacs: Rename --union-type to --check-lisp-type. Define CHECK_LISP_OBJECT_TYPE insted of USE_LISP_UNION_TYPE. * admin/CPP-DEFINES (DEBUG_LISP_OBJECT_TYPE): Renamed from USE_LISP_UNION_TYPE. * src/lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct instead of union. (XLI, XIL): Define. (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG): Use them. * src/emacs.c (gdb_use_struct): Renamed from gdb_use_union. * src/.gdbinit: Check gdb_use_struct instead of gdb_use_union. * src/alloc.c (widen_to_Lisp_Object): Removed. (mark_memory): Use XIL instead of widen_to_Lisp_Object. * src/frame.c (delete_frame): Remove outdated comment. * src/w32fns.c (Fw32_register_hot_key): Use XLI instead of checking USE_LISP_UNION_TYPE. (Fw32_unregister_hot_key): Likewise. (Fw32_toggle_lock_key): Likewise. * src/w32menu.c (add_menu_item): Likewise. (w32_menu_display_help): Use XIL instead of checking USE_LISP_UNION_TYPE. * src/w32heap.c (allocate_heap): Don't check USE_LISP_UNION_TYPE.

2012-06-12USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)Paul Eggert1-44/+21
* alloc.c (make_number) [!defined make_number]: Remove, as lisp.h always defines this now. (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now. (roundup_size): Verify that it is a power of 2. * data.c (Fmake_variable_buffer_local, Fmake_local_variable): * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO. * lisp.h (USE_LSB_TAG): Allow the builder to compile with -DUSE_LSB_TAG=0, to override the automatically-selected default. USE_LSB_TAG now is always defined to be either 0 or 1. All uses changed. (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the code works fine either way, and efficiency is not a concern here, as the union type is for debugging, not for production. (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]: Use an inline function on all platforms when using the union type, since this is simpler and 'static inline' can be used portably within Emacs now. (LISP_INITIALLY_ZERO): New macro. (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove. (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

* src/lisp.h (struct vectorlike_header): New field `nbytes', adjust comment accordingly. * src/alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK' to denote vector blocks. Adjust users (live_vector_p, mark_maybe_pointer, valid_lisp_object_p) accordingly. (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG. (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES), (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX), (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST), (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

Allocate new vector from block if vector size is less than or equal to VBLOCK_BYTES_MAX. (Fgarbage_collect): Move all vector sweeping code to sweep_vectors. (init_alloc_once): Add call to init_vectors. * doc/lispref/internals.text (Garbage Collection): Document new vector management code and vectorlike_header structure.

2012-04-22Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.Paul Eggert1-1/+1
* alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]: Do not assume ptrdiff_t is the same width as 'int'.
2012-04-22* alloc.c: Handle unusual debugging option combinations.Paul Eggert1-10/+11
(GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK, since the two debugging options are incompatible. (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS is defined. (mem_init, mem_insert, mem_insert_fixup): Define if GC_MARK_STACK || GC_MALLOC_CHECK. (NEED_MEM_INSERT): Remove; no longer needed.

2012-04-15Fix minor alloc.c problems found by static checking.Paul Eggert1-1/+15
* alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]: New extern decls, to avoid calling undeclared functions. (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT) && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used. (NEED_MEM_INSERT): New macro. (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

2012-04-07Avoid unnecessary pointer scanning in garbage collection (Bug#10780).Paul Eggert1-25/+28
* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro. (mark_memory): Mark Lisp_Objects only if pointers might hide in objects, as mark_maybe_pointer will catch them otherwise. (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed. * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
2012-03-02lispref/internals.texi Memory Usage tiny changeGlenn Morris1-1/+3
* doc/lispref/internals.texi: (Memory Usage): Copyedit. * src/alloc.c (misc-objects-consed): Doc fix.

2012-02-25* alloc.c (mark_memory): Conditionalize recent fix on USE_USB_TAG.Paul Eggert1-0/+2
2012-02-25Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).Paul Eggert1-1/+26
Suggested by Stefan Monnier in <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>. * alloc.c (widen_to_Lisp_Object): New static function. (mark_memory): Also mark Lisp_Objects by fetching pointer words and widening them to Lisp_Objects. This would work even if USE_LSB_TAG is defined and wide integers are used, which might happen in a future version of Emacs.

2011-11-10Standardize on VIRT_ADDR_VARIES behavior; otherwise, valgrindPaul Eggert1-7/+1
does not work on some platforms. Problem reported by Andreas Schwab in <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>. * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES is set, removing the need for VIRT_ADDRESS_VARIES. (PURE_P): Use a more-efficient implementation that needs just one comparison, not two: on x86-64 with GCC 4.6.2, this cut down the number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge) to 4 (xorl, subq, cmpq, setbe). * alloc.c (pure): Always extern now, since that's the VIRT_ADDR_VARIES behavior. (PURE_POINTER_P): Use a single comparison, not two, for consistency with the new puresize.h. * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed. * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h: Remove VIRT_ADDR_VARIES no longer needed.
2011-11-06* alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).Paul Eggert1-1/+6
This is also needed for porting to any host where GC_MARK_STACK is not GC_MAKE_GCPROS_NOOPS. (which_symbols): Use it.
2011-10-29* alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,Paul Eggert1-1/+2
so that this new function doesn't get optimized away by a whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
2011-10-29Fix the `xbytecode' user-defined command in .gdbinit.Eli Zaretskii1-0/+49
src/.gdbinit (xprintbytestr): New command. (xwhichsymbols): Renamed from `which'; all callers changed. (xbytecode): Print the byte-code string as well. src/alloc.c (which_symbols): New function.
2011-10-11* alloc.c (Fgc_status): Do not access beyond zombies arrayDmitry Antipov1-2/+2
boundary if nzombies > MAX_ZOMBIES. * alloc.c (dump_zombies): Add missing format specifier.
2011-10-07* alloc.c: Add comment.Paul Eggert1-0/+5
2011-10-07Fix alignment-related core dump during GC.Paul Eggert1-20/+17
* configure.in (GC_LISP_OBJECT_ALIGNMENT): Remove. This is now done by src/alloc.c. * src/alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__ or sizeof. __alignof__ gives the wrong answer on Fedora x86-64 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int; this makes Emacs dump core during garbage collection on rare occasions. sizeof is obviously inferior to offsetof here, so stick with offsetof. (GC_POINTER_ALIGNMENT): New macro. (mark_memory): Omit 3rd (offset) arg; caller changed. Don't assume EMACS_INT alignment is the same as pointer alignment.
2011-10-06* alloc.c (mark_memory): Omit 3rd (offset) arg; caller changed.Paul Eggert1-13/+16
Don't assume EMACS_INT alignment is the same as pointer alignment. (GC_POINTER_ALIGNMENT): New macro.
2011-10-06[ChangeLog]Paul Eggert1-9/+3
* configure.in (GC_LISP_OBJECT_ALIGNMENT): Remove. This is now done by src/alloc.c. [src/ChangeLog] * alloc.c: (GC_LISP_OBJECT_ARGUMENT): Use offsetof, not __alignof__ or sizeof. __alignof__ gives the wrong answer on the x86 with GCC.
2011-09-30Remove dependency on glibc malloc internals.Paul Eggert1-2/+45
* alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move back here from lisp.h, but with their new implementations. (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here. * charset.c (charset_table_init): New static var. (syms_of_charset): Use it instead of xmalloc. This removes a dependency on glibc malloc internals. See Eli Zaretskii's comment in <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>. * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move back to alloc.c. (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
2011-09-29Port --enable-checking=all to Fedora 14 x86.Paul Eggert1-32/+15
* alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move to lisp.h. (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc) (overrun_check_realloc, overrun_check_free): Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t). That way, xmalloc returns a properly-aligned pointer even if XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened to align OK on typical 64-bit hosts, but not on Fedora 14 x86. * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD into account when calculating the initial malloc maximum. * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE): Move here from alloc.c, so that charset.c can use it too. Properly align; the old code wasn't right for common 32-bit hosts when configured with --enable-checking=all. (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
2011-09-29* alloc.c: Do not assume sizeof (size_t) is a multiple of 8Paul Eggert1-17/+34
when debugging. (alignof, XMALLOC_BASE_ALIGNMENT, XMALLOC_HEADER_ALIGNMENT) (XMALLOC_OVERRUN_SIZE_SIZE): New macros. (XMALLOC_OVERRUN_CHECK_OVERHEAD, xmalloc_put_size, xmalloc_get_size) (overrun_check_malloc, overrun_check_realloc, overrun_check_free): Replace uses of sizeof (size_t) with XMALLOC_OVERRUN_SIZE_SIZE.

(struct buffer_text, struct buffer): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough. Use EMACS_INT, not int, where int might not be wide enough. * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts. Remove unnecessary memory-full test. Use EMACS_INT, not ptrdiff_t or int, where ptrdiff_t or int might not be wide enough. * callint.c (Fcall_interactively): Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts. * callproc.c (call_process_kill, Fcall_process): Don't assume pid_t fits into an Emacs fixnum.

(resolve_symbol_ccl_program): Check that vector header is in range. Always copy the vector, so that we can check its contents reliably now rather than having to recheck each instruction as it's being executed. Check that vector words fit in 'int'.

2011-09-09Whitespace changes.Juanma Barranquero1-11/+11
2011-08-04Adjust in response to jan.h.d's comments.Paul Eggert1-0/+88
See, for example <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#26>.
2011-08-04Check for pthread and use it if found.Jan Djärv1-8/+10
* configure.in (HAVE_PTHREAD): Add check for -lpthread. (HAVE_GTK_AND_PTHREAD): Remove. * src/Makefile.in (LIB_PTHREAD): New variable. (LIBES): Add LIB_PTHREAD (Bug#9216). * src/alloc.c, src/emacs.c, src/gmalloc.c, src/gtkutil.c, src/keyboard.c, src/syssignal.h: Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
2011-07-28* alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.Paul Eggert1-1/+5
Without this fix, if a signal arrives just after memory fills up, 'malloc' might be invoked reentrantly.
2011-07-18* alloc.c (valid_pointer_p): Use pipe, not open.Paul Eggert1-5/+5
This fixes some permissions issues when debugging.
2011-07-14* alloc.c (__malloc_size_t): Remove.Paul Eggert1-9/+4
All uses replaced by size_t. See Andreas Schwab's note <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
2011-07-12* alloc.c (gc_sweep): Don't read past end of array.Paul Eggert1-1/+1
In theory, the old code could also have corrupted Emacs internals, though it'd be very unlikely.
2011-07-10ProtoizeAndreas Schwab1-1/+1
* src/alloc.c (reset_malloc_hooks): Protoize. * src/cm.c (losecursor): Likewise. * src/ralloc.c (r_alloc_check): Likewise.
2011-07-07* alloc.c: Integer signedness and overflow fixes.Paul Eggert1-58/+78
Do not impose an arbitrary 32-bit limit on malloc sizes when debugging. (__malloc_size_t): Default to size_t, not to int. (pure_size, pure_bytes_used_before_overflow, stack_copy_size) (Fgarbage_collect, mark_object_loop_halt, mark_object): Prefer ptrdiff_t to size_t when either would do, as we prefer signed integers. (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro. (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer): Now const. Initialize with values that are in range even if char is signed. (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ... (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed. These functions do the right thing with sizes > 2**32. (check_depth): Now ptrdiff_t, not int. (overrun_check_malloc, overrun_check_realloc, overrun_check_free): Adjust to new way of storing sizes. Check for size overflow bugs in rest of code. (STRING_BYTES_MAX): Adjust to new overheads. The old code was slightly wrong anyway, as it missed one instance of XMALLOC_OVERRUN_CHECK_OVERHEAD. (refill_memory_reserve): Omit needless cast to size_t. (mark_object_loop_halt): Mark as externally visible.
