* * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTESDmitry Antipov2012-07-031-1/+1
| | | | | is enabled, avoid dereferencing NULL current_sblock if running undumped.
* Cleanup basic buffer management.Dmitry Antipov2012-07-031-77/+54
| | | | | | | | | | | | | | | | | | | * buffer.h (struct buffer): Change layout to use generic vector marking code. Fix some comments. Change type of 'clip_changed' to bitfield. Remove unused #ifndef old. (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove. (GET_OVERLAYS_AT): Fix indentation. (for_each_per_buffer_object_at): New macro. * buffer.c (clone_per_buffer_values, reset_buffer_local_variables) (Fbuffer_local_variables): Use it. (init_buffer_once, syms_of_buffer): Remove unused #ifndef old. * alloc.c (allocate_buffer): Adjust to match new layout of struct buffer. Fix comment. (mark_overlay): New function. (mark_buffer): Use it. Use mark_vectorlike to mark normal Lisp area of struct buffer. (mark_object): Use it. Adjust marking of misc objects and related comments.
* * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"Paul Eggert2012-07-021-2/+0
| | | | | | wrapper that is not needed because the wrapped code is a no-op (zero machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined. This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
* * alloc.c (mark_buffer): Simplify. Remove prototype.Dmitry Antipov2012-07-021-112/+125
| | | | | | | (mark_object): Add comment. Reorganize marking of vector-like objects. Use CHECK_LIVE for all vector-like ojects except buffers and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid redundant calls to mark_vectorlike for bool vectors.
* * src/editfns.c (region_limit): Clip to narrowing.Stefan Monnier2012-06-281-1/+2

* Enlarge NSTATICS to 0x650.Eli Zaretskii2012-06-221-1/+1
| | | | | | | src/alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER aborts in staticpro during startup. (Without -DBYTE_CODE_METER, staticidx goes up to 1597 out of 1600 = 0x640.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.

* USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)Paul Eggert2012-06-121-44/+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.

(allocate_vector_from_block, init_vectors, allocate_vector_from_block) (sweep_vectors): New functions. (allocate_vectorlike): Return `zero_vector' as the only vector of 0 items. 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.
