* config.gcc: Support core2 processor.

* c-common.c (vector_types_convertible_p): Treat opaque types as
|

always convertible if they have the same size, but not otherwise.

* c.opt: Add -flax-vector-conversions.
|
||||
* c-typeck.c (convert_for_assignment): Pass flag to
|
||||
vector_types_convertible_p to allow emission of note.
|
||||
(digest_init): Likewise.
|
||||
* c-opts.c: Handle -flax-vector-conversions.
|
||||
* c-common.c (flag_lax_vector_conversions): New.
|
||||
(vector_types_convertible_p): Unless -flax-vector conversions
|
||||
has been passed, disallow conversions between vectors with
|
||||
differing numbers of subparts and/or element types. If such
|
||||
a conversion is disallowed, possibly emit a note on the first
|
||||
occasion only to inform the user of -flax-vector-conversions.
|
||||
The new last argument specifies this.
|
||||
* c-common.h (flag_lax_vector_conversions): New.
|
||||
(vector_types_convertible_p): Add extra argument.
|
||||
* config/i386/i386.c (ix86_init_mmx_sse_builtins): Use
|
||||
char_type_node for V*QI type vectors.
|
||||
* config/rs6000/rs6000-c.c (altivec_overloaded_builtins):
|
||||
Update to satisfy new typechecking rules.
|
||||
* config/rs6000/altivec.h (vec_cmple): Use vec_cmpge, for both
|
||||
C and C++ variants.
|
||||
* doc/invoke.texi (C Dialect Options): Document
|

-flax-vector-conversions.
