I'd used mode-based element types in the SVE ACLE implementation, but
it turns out that they don't correspond to the <stdint.h> types used by
ILP32 newlib. GCC already knows what the correct <stdint.h> types are,
I just wasn't using the right interface to find them.
A consequence of this is that ILP32 newlib code needs to cast "int *"
pointers to "int32_t *" before passing them to s32 loads and stores,
since int32_t is defined as "long int" rather than "int". That matches
the normal C++ overloading behaviour for this target, where passing
"int *" to:
void f(int32_t *);
void f(int64_t *);
would be ambiguous. It also matches the corresponding <arm_neon.h>
behaviour.

The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
