The next log entry shows the actual changes by Paul Eggert.
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.
src/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.
src/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.
src/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".
src/buffer.h (struct buffer): Likewise.
src/font.h (struct font_spec, struct font_entity, struct font): Likewise.
src/frame.h (struct frame): Likewise.
src/process.h (struct Lisp_Process): Likewise.
src/termhooks.h (struct terminal): Likewise.
src/window.c (struct save_window_data, struct saved_window): Likewise.
src/window.h (struct window): Likewise.
src/alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
src/buffer.c (init_buffer_once): Likewise.
src/lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
special case.
src/process.c (Fformat_network_address): Use local var for size,
for brevity.
src/fns.c (vector): Remove; this old hack is no longer needed.
src/bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
