[Bug target/36925] New: "3.5 malloc(), vec_malloc(), and new" part of the Alivec PIM is not implemented

[pinskia at gcc dot gnu dot org]

When I was looking up something in the Altivec PIM if "vector bool a;" was
valid, I 
noticed a section which I had never read before, most likely because it is part
of the ABI 
section of the Altivec PIM.

The specific section says:
3.5  malloc(), vec_malloc(), and new 
In the interest of saving space, malloc(), calloc(),  and realloc() are not
required to return 
a 16-byte aligned address. Instead, a new set of memory management functions is 
introduced that return a 16-byte aligned address. The new functions are named 
vec_malloc(), vec_calloc(), vec_realloc(), and vec_free(). The two sets of
memory 
management functions may not be interchanged: memory allocated with malloc(), 
calloc(), or realloc() may only be freed with free() and reallocated with
realloc(); memory 
allocated with vec_alloc(), vec_calloc(), or vec_realloc() may only be freed
with vec_free() 
and reallocated with vec_realloc(). The user must use the appropriate set of
functions 
based on the alignment requirement of the type involved. In the case of the C++ 
operator new, the implementation of new is required to use the appropriate set
of 
functions based on the alignment requirement of the type.
