[PATCH 0/7] sim, sim/ARCH: Add ATTRIBUTE_PRINTF

Hello,

[Background]

When we build Binutils and GDB with Clang, it causes a build failure due to
warnings generated by Clang and the default -Werror configuration.

I finally managed to make ALL ARCHITECTURE ENABLED Binutils and GDB
-Werror-free on Clang 15.0.0 (note that this does not necessarily mean
warning-free) and this patchset is a part of it
(the printf-like functions in the simulator).

Full Clang 15.0.0 -Werror-free branch is available at:
<https://github.com/a4lg/binutils-gdb/tree/clang-nowarn-dev>

[About this Patchset]

Clang generates a warning if the format string of a printf-like function is
not a literal ("-Wformat-nonliteral"). On the default configuration, it
causes a build failure (unless "--disable-werror" is specified).

To avoid warnings on the printf-like wrapper, it requires proper
__attribute__((format)) and we have ATTRIBUTE_PRINTF macro for this reason.

This patchset adds ATTRIBUTE_PRINTF to all functions that require
ATTRIBUTE_PRINTF macro.

Note that most of the changes are made to architecture without any arch
maintainer so I feel sorry for Andrew and Mike.

Thanks,
Tsukasa
