alloc metadata may be attached to any instruction returning a
- pointer. It can be used to express the size and offset relative to the
- beginning of the buffer pointed by.
-
-
-
-The first parameter is a function that returns the size of the buffer, and
- the second (optional) parameter is a function that returns the offset from
- the beginning of the buffer. If the second parameter is not present or null,
- the offset is assumed to be null. Both functions must be either readonly or
- readnone.
-alloc metadata can have additional parameters, which are passed to
- the size and offset functions when they are evaluated. Therefore the size and
- offset functions must have the same signature.

Examples:
-
-
- ; size of buffer allocated by this call is my_malloc_size(%s), and offset=0
- %a = call my_malloc(%s), !alloc !{i32 (i32)* @my_malloc_size, null, i32 %s}
-
- ; size of the buffer pointed by *ptr is size(%x), and offset=offset(%x)
- %b = load i8** %foo, !alloc !{i32 (i32)* @size, i32 (i32)* @offset, i32 %x}
-
- ; size of buffer allocated by this call is foo_size(), and offset=0
- %a = call alloc_foo(%s), !alloc !0
-...
-!0 = metadata {i32 ()* @foo_size}
