+
+ Fix a problem with aliasing and vector headers.
+ GCC 4.6.0 optimizes based on type-based alias analysis. For
+ example, if b is of type struct buffer * and v of type struct
+ Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
+ != &v->size, and therefore "v->size = 1; b->size = 2; return
+ v->size;" must therefore return 1. This assumption is incorrect
+ for Emacs, since it type-puns struct Lisp_Vector * with many other
+ types. To fix this problem, this patch adds a new type struct
+ vector_header that documents the constraints on layout of vectors
+ and pseudovectors, and helps optimizing compilers not get fooled
+ by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
+ XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
+ * lisp.h (XVECTOR_SIZE): New convenience macro. All previous uses of
+ XVECTOR (foo)->size replaced to use this macro, to avoid the hassle
+ of writing XVECTOR (foo)->header.size.
+ * lisp.h: Say "vectorlike header" rather than "vector header.
+ (struct vectorlike_header): Rename from struct vector_header.
+ (XVECTORLIKE_HEADER_SIZE): Renamed from XVECTOR_HEADER_SIZE.
+ All uses changed.
+ (XVECTOR_HEADER_SIZE): New macro, for use in XSETPSEUDOVECTOR.
+ (XSETTYPED_PVECTYPE): New macro, specifying the name of the size
+ member.
+ (XSETPVECTYPE): Rewrite in terms of new macro.
+ (XSETPVECTYPESIZE): New macro, specifying both type and size.
+ This is a bit clearer, and further avoids the possibility of
+ undesirable aliasing.
+ (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
+ (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR
+ and XVECTOR_HEADER_SIZE.
+ (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
+ since Lisp_Subr is a special case (no "next" field).
+ (ASIZE): Rewrite in terms of XVECTOR_SIZE.
+ (struct vector_header): New type.
+ (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
+ object, to help avoid aliasing.
+ (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
+ (SUBRP): Likewise, since Lisp_Subr is a special case.
+
+ * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
+ (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
+ (struct Lisp_Hash_Table): Combine first two members into a single
+ struct vector_header member. All uses of "size" and "next" members
+ changed to be "header.size" and "header.next".
+ * buffer.h (struct buffer): Likewise.
+ * font.h (struct font_spec, struct font_entity, struct font): Likewise.
+ * frame.h (struct frame): Likewise.
+ * process.h (struct Lisp_Process): Likewise.
+ * termhooks.h (struct terminal): Likewise.
+ * window.c (struct save_window_data, struct saved_window): Likewise.
+ * window.h (struct window): Likewise.
+ * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
+ Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
+ * buffer.c (init_buffer_once): Likewise.
+ * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
+ special case.
+ * process.c (Fformat_network_address): Use local var for size,
+ for brevity.
+ * fns.c (vector): Remove; this old hack is no longer needed.
+ * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.

+
+ * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
