The patch backports from mainline to 3.4-branch changes to support the
AltiVec high-level language interface. It includes several different
patches and has been tested as a single patch on powerpc64-linux. In
addition to the AltiVec tests that are already in the branch and that
this patch brings up to date, I've also tested this with all other
altivec* tests in the GCC testsuite, plus gcc.dg/vmx. I'd like to copy
those tests to the branch but will do that in a separate patch.
Changes to the files doc/extend.texi and config/rs6000/altivec.h are
huge, so they are attached as bzip2 files. This version of altivec.h
includes a change that I had expected to be in mainline by now but
isn't, which is replacement of 'pixel' and 'bool' with '__pixel' and
'__bool'. I'll start testing that change for mainline to get it in
there first, unless Ben Elliston beats me to it. Or, if folks prefer,
I'll remove that change from this patch and retest.
Some of these changes affect Darwin, so I'd appreciate it if someone
can test this on powerpc-apple-darwin.
OK for 3.4-branch, after testing on Darwin?

* c-common.c (vector_size_helper): Remove; call
reconstruct_complex_type() instead.
* hooks.c (hook_constcharptr_tree_null): New hook.
* hooks.h (hook_constcharptr_tree_null): New prototype.
* target-def.h (TARGET_MANGLE_FUNDAMENTAL_TYPE): New target hook.
* target.h (mangle_fundamental_type): New target hook.
* tree.c (reconstruct_complex_type): New function
(formerly vector_size_helper() in c-common.c).
(make_vector): Make externally visible.
* tree.h (reconstruct_complex_type, make_vector): Add prototypes.
* doc/extend.texi (AltiVec builtins): Document additional differences
from the Motorola AltiVec PIM.
* doc/tm.texi (TARGET_MANGLE_FUNDAMENTAL_TYPE): Document.
* config/darwin.h (TARGET_OPTION_TRANSLATE_TABLE): Refer to
SUBTARGET_OPTION_TRANSLATE_TABLE for architecture-specific options.
* config/i386/darwin.h (SUBTARGET_OPTION_TRANSLATE_TABLE): Define it.
* config/rs6000/altivec.h: #error out if '-maltivec' not specified.
(vector, pixel, bool): #define to __vector, __pixel and __bool.
Change vector to __vector (except for the `vector' macro itself).
(__un_args_eq, __bin_args_eq, __tern_args_eq): Move to C-specific
portion of header.
(__altivec_link_error_invalid_argument): Remove prototype; will use
__builtin_altivec_compiletime_error("vec_*") instead.
(vec_*): Fix/complete set of available operation overloads given the
existence of distinct 'vector bool ...' and 'vector pixel' types;
tighten cv-correctness of pointer arguments; in C, always check for
correct argument types before macro expansion.
(vec_splat_s8, vec_splat_s16, vec_splat_s32, vec_splat_u8,
vec_splat_u16, vec_splat_u32): Change C++ definitions to accept a
'const int' argument; the prototypes already do.
(vec_dst, vec_dstst, vec_dststt, vec_dstt, vec_sld, vec_splat): Add
prototypes, marked with always_inline attribute.
* config/rs6000/darwin.h (SUBTARGET_OPTION_TRANSLATE_TABLE): New macro
defining Darwin/PowerPC-specific '-f[no-]altivec' and
'-W[no-]altivec-long-deprecated' switches.
* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): Pre-define
'__vector', '__pixel' and '__bool' macros using
'__attribute__((altivec(...)))' types.
* config/rs6000/rs6000.c (bool_char_type_node, bool_short_type_node,
bool_int_type_node, pixel_type_node, bool_V16QI_type_node,
bool_V8HI_type_node, bool_V4SI_type_node, pixel_V8HI_type_node):
New type nodes.
(rs6000_warn_altivec_long, rs6000_warn_altivec_long_switch): New, for
handling '-W[no-]altivec-long-deprecated'.
(rs6000_override_options): Handle '-W[no-]altivec-long-deprecated'.
(rs6000_expand_binop_builtin, rs6000_expand_ternop_builtin,
altivec_expand_dst_builtin): Remove casts from integer literals.
(altivec_expand_builtin): Likewise; handle expansion of new
'__builtin_altivec_compiletime_error' function.
(rs6000_init_builtins): Initialize 'vector bool ...' and 'vector pixel'
types, and make them distinct from other vector types; register
'__builtin_altivec_compiletime_error' function.
(print_operand): For 'P', print a full target register name instead of
merely its number.
(rs6000_attribute_table): Add "altivec" attribute.
(rs6000_handle_altivec_attribute): New function.
(rs6000_common_init_builtins): Rename v4si_ftype_char, v8hi_ftype_char,
v16qi_ftype_char, v4sf_ftype_v4si_char, v4si_ftype_v4sf_char,
v4si_ftype_v4si_char, v8hi_ftype_v8hi_char, v16qi_ftype_v16qi_char,
v16qi_ftype_v16qi_v16qi_char, v8hi_ftype_v8hi_v8hi_char,
v4si_ftype_v4si_v4si_char and v4sf_ftype_v4sf_v4sf_char to
end in ..._int; change them to accept an int instead of a char
as the last parameter.
(altivec_expand_dst_builtin): Treat expansion as completed even if
literal argument is invalid (so that other expansions are not tried
in vain).
(TARGET_MANGLE_FUNDAMENTAL_TYPE): Point target hook at
rs6000_mangle_fundamental_type.
(rs6000_mangle_fundamental_type): New function.
* config/rs6000/rs6000.h (TARGET_OPTIONS): Describe
'-m[no-]-warn-altivec-long' (which '-W[no-]altivec-long-deprecated'
maps to).
(rs6000_warn_altivec_long, rs6000_warn_altivec_long_switch): Forward
declare.
(ALTIVEC_BUILTIN_COMPILETIME_ERROR): New built-in enumeration.
cp:
* Make-lang.in (cp/mangle.o): Depend on $(TARGET_H).
* mangle.c (write_type): Add call to 'mangle_fundamental_type'
target hook.
* tree.c (pod_type_p): Treat VECTOR_TYPEs as PODs.
testsuite:
* lib/target-supports.exp (check_vmx_hw_available): New.
* g++.dg/ext/altivec-1.C: XFAIL powerpc-ibm-aix. Correct dg syntax.
* gcc.dg/altivec-1.c: XFAIL powerpc-ibm-aix, powerpc-eabispe.
* gcc.dg/altivec-2.c: Generalize target.
* gcc.dg/altivec-3.c: XFAIL powerpc-ibm-aix, powerpc-eabispe.
Use vector_size attribute. Do runtime check for VMX hardware.
* gcc.dg/altivec-4.c: XFAIL powerpc-ibm-aix, powerpc-eabispe.
Use vector size attribute.
* gcc.dg/altivec-5.c: Generalize target.
* gcc.dg/altivec-7.c: XFAIL powerpc-ibm-aix. Replace long* with int*.
* gcc.dg/altivec-8.c: XFAIL powerpc-ibm-aix.
* gcc.dg/altivec-9.c: Generalize target.
* gcc.dg/altivec-10.c: XFAIL powerpc-ibm-aix and powerpc-eabispe.
* gcc.dg/altivec-11.c: Ditto.
* gcc.dg/altivec-varargs-1.c: Ditto.

+@deftypefn {Target Hook} {const char *} TARGET_MANGLE_FUNDAMENTAL_TYPE (tree @var{type})
+If your target defines any fundamental types, define this hook to
+return the appropriate encoding for these types as part of a C++
+mangled name. The @var{type} argument is the tree structure
+representing the type to be mangled. The hook may be applied to trees
+which are not target-specific fundamental types; it should return
+@code{NULL} for all such types, as well as arguments it does not
+recognize. If the return value is not @code{NULL}, it must point to
+a statically-allocated string constant.
+
+Target-specific fundamental types might be new fundamental types or
+qualified versions of ordinary fundamental types. Encode new
+fundamental types as @samp{@w{u @var{n} @var{name}}}, where @var{name}
+is the name used for the type in source code, and @var{n} is the
+length of @var{name} in decimal. Encode qualified versions of
+ordinary types as @samp{@w{U @var{n} @var{name} @var{code}}}, where
+@var{name} is the name used for the type qualifier in source code,
+@var{n} is the length of @var{name} as above, and @var{code} is the
+code used to represent the unqualified version of this type. (See
+@code{write_builtin_type} in @file{cp/mangle.c} for the list of
+codes.) In both cases the spaces are for clarity; do not include any
+spaces in your string.
+
+The default version of this hook always returns @code{NULL}, which is
+appropriate for a target that does not define any new fundamental
+types.
